It is another digitized sound manipulator, but is far more advanced than its predecessors. W}The main feature of Digi-Studio is that it plays samples in real musical pitch, over a 3 octave range. The keyboard player alX}so has fully responsive keys. This basically means that the sound will only play for as long as you hold the key down. This iY}s exactly how synthesizers work, and pianos to some extent (the sound here still lingers after releasing the key). This featuZ}re means that you can play real music using the keyboard like a piano keyboard. Digi-Studio also allows you to have 3 samples[} in memory at once, and you can change the playback sample very easily while actually playing music. Another feature added to\} Digi-Studio, is that samples are wiped before new ones are loaded. This avoids the overlapping which was a problem with the ]}old DMS. At present, only the keyboard player and the tune player are available to the public. The song editor is still^} in development (more on this in section 2). The tune player will play pre-programmed tune files using any of the samples on _}the Digi-Studio disk. Five tunes are supplied with Digi-Studio for you to play. The keyboard player and tune player are`} currently being sold as "package 1". Also supplied are about 25 samples of all types with lots of synth sounds, animal sounda}s, churchbells, a baby crying, and lots of other sounds. The manual has been printed using Daisy Dot 3, and is supplied as anb} A5 booklet with a nice green stiff cover. The manual is quite detailed, though only 6 pages long. Package 1 with DS/SDc} disk, A5 manual, and P&P costs 5pounds. It is only available direct from me. Side 2 of the News-Disk (the catalogue disk) cod}ntains a copy of the official sales blurb along with an order form. If you are unable to print the form out, then just write e}your order on paper and send it with your cheque/PO.Part 2 - Behind the scenes!--------------------------- Well nowf} we've got the sales pitch out of the way, I can go on to talk about what went on during the development of Digi-Studio, and g}also what is planned for the future. In the summer of 1990, I decided that DMS just wasn't up to much! I knew that I neh}eded to get round the problem of not having real pitch. Solving this problem proved to be easier than I first thought! In faci}t, the clue came from the crummy 800XL manual supplied with the machine. The relationship formula between frequency and time j}is what I needed. Unfortunately, the Replay M/C player routine was just not up to coping with this. Stuck again! Soon ak}fter, though, I got a copy of the new Antic Sampling Processor. The M/C player with this was radically different to Replay's.l} It could do exactly what I needed it to with little modification. The next step was to work out count-down times for em}ach sound frequency. My first thought was to use the 800XL manual again. This hada diagram of pitches and the corresponding nn}umber for the Basic SOUND command. Theoretically, these would be what I needed. Wrong! Some worked, some didn't! I needed helo}p! At this point I employed the help of David Robinson. He's an old friend of mine from way back. He's currently a 3rd p}year student in maths at Hull University. But, his musical talents run just as far. He's an accomplished organist, and is higq}hly qualified in music theory. We spent days working out these count-down values! Some were still not right, and it was time r}for us to depart to University (me for the first time!) The small holidays at Christmas and Easter aren't long enough to do as}ny serious work, so we put Digi-Studio on ice until the next summer holiday. Summer 1991 came, and back to work we wentt}. We finally worked out a complete set of pitch values! Back in summer 1990 we started writing a tune editor, but hit problemu}s, so many of the early test routines were hard coded in Basic. One thing we managed to do last year, was to sample plenty ofv} sounds, so we didn't spend to long this year sampling. One thing I realized this year was that I wouldn't be able to use thew} ASP code because of copyright reasons. So I had to write my own M/C play routines! This was perhaps the hardest part of writx}ing Digi-Studio! It drove me up the wall! The finished code contained the techniques used in the ASP code, but without directy}ly ripping code off. It also had to remain compatible with Replay samples. Because we hit problems with the song editorz}, we decided to work on a keyboard player. These are easy to write, and would also give usa chance to make sure that the pitc{}h values we worked out really were correct! But, it still had the same problems as DMS did. You had to specify in advance how|} long each note would play for. This just wasn't acceptable anymore. It was at this point that I remembered a program in Comp}}uter and Video Games magazine from 1985, which dealt with the volume only sound technique. So I dug through the archives and ~}found the article, and also a copy on disk. The answer was in there, and my M/C player code only needed a little tweaking to }do it! This is why Digi-Studio has two player programs on the disk - one for the keybaord player, and the other for the tune }player. The early test version of the keyboard player was a bit primitive. You had to have your sample (only 1 allowed!}) in the correct part of memory beforehand, and had to run another program to load in a new one. You also had to make sure yo}u had the correct M/C player routine loaded. It didn't have any pretty front-end, or menu like it has now. Only when we were }satisfied that it worked, did I add the menu and load options and add the 3 sample banks option. Then I realized that w}e had some tunes ready with our very primitive song editor, and that it would be nice to include them with Digi-Studio. So, I} wrote a song player which didn't take too long. This is just meant as a taster for what is to come. The next problem w}e encountered was the fact that everything was written in Turbo-Basic, which is PD. We wouldn't be able to charge for this, a}nd may not even be allowed to put it on the Digi-Studio disk. But, as long as we made it known that Turbo was being supplied }as a freebie then we'd be OK. At the end of the summer we had all the development done, and lots of samples, so you'd p}robably think that would be it! Wrong! There was the dreaded manual to write. I started this in late September. The first dra}ft was scribbled on paper, adding a bit each time I had a spare minute. After it was ready on paper, I typed it up using Atar}iwriter. I printed it out on my XMM801, and I thought it was good. Wrong again! I gave it to a mate to proof-read (Thanks to }Mike Watson for this) who pulled it to pieces! Lots needed doing to it. His first reaction was "What? It's gonna look like TH}IS!!". I had to rethink presentation, and contents! Several drafts later and it was ready. Presentation was still a problem, }so I printed it using Daisy Dot 3 and it looked quite good. The cover was done using the little DTP on PD100. Not really much} of a job for a DTP, but it looks OK! It was now looking likely that I would be able to release it at AMS5 in November.} So, out came the programs for tidying, out came all the samples and tunes (at this point Digi-Studio was on about 15 disks!)}, and a master disk was created. A little intro was done (the nice little scrolling bit at during boot up!), and there it was}. The next step was to create a release master, the difference being that the programs are protected. This caused problems in} Turbo-Basic, so a compromise had to be used. And there it was. Pre-release copies were sent to Mike Blenkiron and Mark Keate}s about 5 days before the show. Thanks to Mark for his radical suggested changes to the manual, but 5 days before release is }NOT the time to make changes!! Then it suddenly struck me. The manuals hadn't been printed. So, the day before the show} I turned up at Kall Kwik printing in Doncaster with a pile of A4 printouts, and asked them to turn them into A5 booklets to }be ready the same day - caused a few laughs did that one! "What colour would you like the cover?", he said. Err, woops! I had} no idea! So out came samples of the available colours. I just closed my eyes and picked a colour at random! Yes, lots of tho}ught and consideration goes into my manuals!! Digi-Studio was officially released at AMS5. We had a machine playing it }all day, and we had quite a bit of positive feedback. Thanks to all those who parted with their cash! Currently, the so}ng editor is still in production. We are hoping for a release in the summer. I have very nearly finished a sample edito}r, to allow samples to be changed and new ones created using a joystick and sample patterns on the screen. It also allows you} to reverse parts of the sample, and copy chunks around to create some really weird samples! Release of this will be in a cou}ple of months. This disk will also contain more samples and tunes, along with a utility to allow you to put tunes in your own} Basic programs.is disk will also contain more samples and tunes, along with a utility to allow you to put tunes in your ownThis article was taken from the Unix newsnet.

A noble idea, to be sure, but totally impractical. The reason being, that 5-1/4" disks with clumsy o }le DOS 2.0s or 2.5 is the common medium of software exchange. There are just too many 810's, 1050's & XF551's out there, the }y number literally in the millions.For the better part of the past year I have been using 3.5" 720K drives from CSS, I love } them, I call them "The Poor Man's Hard Drive". But I still have to keep a few 1050s around to handle boughten software or p }rogram/data disks I exchange with other people thru the mail.I'm not familiar with the IC 3.5" upgrade.The CSS upgrade co }mes in 3 flavors, as follows:1.) The single 3.5 replacement upgrade;2.) the dual 5.25"/3.5" upgrade;3.) the dual 3.5"/3 }.5" upgrade.All three require an XF551. With item 1.) above, you replace the 5" mech with the 3" mech in the case of the 5 }51. In item 2.), the 3" is simply slaved to the 551; you keep the 5" mech in the 551 & the 3" mech sits on top. And item 3. }) combines 1.) & 2.).The hardware consists of a sealed module with wires you have to solder to various pins on the 8050 CPU }, plus a ROM that replaces the original on the XF551 controller card. Then there's the cables & drive mech. CSS uses 3.5" S }ony mech mounted in a 5.25" frame. I've also successfully used 3.5" Sony mechs purchased for $39 from Jameco.The aesthetic }s of the CSS upgrade leave much to be desired. I was bummed out with the bare mech sitting on top of the 551 with wires hang }ing out. But the mech from CSS can be fitted into a 1050 case (with some labor) & it looks really nice. The color of the CS }S Sony mech is exactly halfway between the grey of the 551 & the ivory of the 1050. No matter which shell you use, it comes }out looking OK. I employed a 1050 whose board already was dead, so I stripped the parts from the board & kept the +5V supply } to run the 3.5" mech. The little drives consume almost no power: 20mA at idle, 800mA full load.I use Sparta 3.2 on these } drives. DS/DD format w/ultraspeed gives you 737K of actual storage.Much simpler to implement than a hard drive, cheaper t }oo. Not as fast, tho, & of course lacking mega storage. Even so, I love it.- BEN POEHLANDAlways The AlchemistStill offi }cially 8bit editor of Current Notes til the end of the year.n so, I love it.- BEN POEHLANDAlways The AlchemistStill offi =This article is about hard drives on the Atari, and was taken from the Unix newsnet, and originally from Z*MAG.

Unfortunately, it is soon to go away. This is from Issue #197 (I think, my memory i}sn't what it use to be and I didn't write it down).Kit KimesAT&T Bell Labs===============================================}======================THE 8-BIT STATE: Adding BIG Power to your little system.by Chuck SteinmanOne of the most signifi}cant time saving and productivity raising peripherals you can add any computer system is a HARD DRIVE. That goes for the 8-b}it Atari too, and once you have one you will wonder why you hadn't upgraded before. There is something about having many meg}abytes of files instantly available on the 8-bit that is nothing short of amazing. And the speed of access and loading is bl}inding--quite literally indistinguishable from the speed of a RAMdisk.While there were hard drives made for the original 80}0, they appear to have gone underground over the years. We'll concentrate on the newer systems.THE HOST ADAPTORThe gatew}ay to hard drive use is the device called a HOST ADAPTOR. There are two main units used in the classic Atari world, the Multi}-I/O (MIO) from ICD, Inc., and the Black Box (BB) by Computer Software Services (CSS). Both provide similar performance, wit}h each offering their own special features. They both connect to the Atari 600XL and 800XL PBI (Parallel Bus Interface) and }to the 130XE through the ECI (Enhanced Cartridge Interface). Several other companies used to market hosts for the classic At}ari, and their products might still be available either second hand or from dusty dealer archives. Beware, it might be impos}sible to find technical support.The MIO has been out for many years, but ICD is presently trying to close out their 8-bit l}ineup. One of the unique features that the MIO offers is its built in RAM. You can order the MIO with either 256K or 1M byt}es of RAM, which can be used as a RAMDisk or a print spooler. The amount of RAM dedicated to each function can be user progr}ammed using the built-in configuration menu.The Black Box does not have a built-in RAMDisk, but does have an optional print}er buffer. There is a print screen button, which will send a text/graphics dump of the current screen contents to your print}er. Another pushbutton will activate the BB debugger, extremely handy for programmers. The BB also has a port on it for a p}arallel floppy drive, but they are not available.Both the MIO and BB will control up to eight disk drives, of which any num}ber can be RAMDisks, standard Atari floppies, or hard drives. You can change the logical drive number of any drive, or swap }drive numbers of two drives. Hard drives can be divided ("partitioned") into several separate sections, each seen as an inde}pendent disk drive.The BB and MIO both offer a serial (modem) port, a parallel (printer) port, and an SASI/SCSI (hard drive}) expansion port. This last port will allow industry standard SASI or SCSI hard disk controllers to be attached using a 50 p}osition ribbon cable.BUILDING A HARD DRIVE SYSTEMAn 8-bit Atari hard drive setup will include several parts: the HOST (p}robably an MIO or BB), a CONTROLLER, a HARD DRIVE, and some kind of case and power supply for it all. Other than the host, a}ll the other parts will be usable on other computers (including the ST) if you later change systems (shame on you). Total co}sts can be as low as under $400 with careful shopping. And you won't really need more than a single floppy anymore, perhaps }freeing up some hardware you can sell. Hard drives are available in a wide range of sizes, from 5 megabytes to hundreds of m}egs. The capacity of your drive is up to you and your budget, but for the relatively small 8-bit applications, even a (very }cheap!) 10 meg drive will hold an incredible array of software. You can also easily add a second drive later.When buying y}our hard disk controller, make sure it matches your hard drive. Controllers are available for Modified FM (MFM) and Run Leng}th Limited (RLL) type drives. RLL will provide 50% more disk space at approximately the same cost, and are usually a bit fas}ter. Don't use MFM drives with an RLL controller, as the increased data density of the RLL system will likely exceed the cap}ability of the MFM drive, leading to data loss sooner or later. You can usually use an RLL drive on an MFM controller with n}o harm, but with only two-thirds of the rated drive capacity.Another option would be to get a drive which has the controlle}r built right on it. These drives tend to be a bit faster and more expensive. These are designated as "SCSI drives" and have} the 50 position ribbon connector right on the drive.A wide variety of cases (most with power supplies) are on the market, }with the most popular being the external "shoebox" type formerly used on the original PCs.To be able to access all of this }disk space, you will need a DOS which will support hard drives --Atari's own DOS systems haven't got the capacity. Both Spar}taDOS (including the cart-based SDX, both sold by ICD, Inc.) and MyDOS 4.50 (included with the BB) fill this need very nicely}. Both support drives with partitions as large as 16 megabytes.Both ICD and CSS offer prepackaged hard drive systems to si}mplify the task of adding a hard drive to your 8-bit. Call CSS or ICD to check their current stock, pricing, or for addition}al information.Resources:Computer Software Services P.O.

The reason is that the two holes for the screws in the sensor casing }are *oval*, which allows for a couple of millimeters of play. Unfortunately, I have no idea how you're supposed to figure ou}t exactly where the right position is!When I first put the sensor back in place, the drive was unable to read *any* sectors} back. Then I slid it over a bit, and thankfully it was able to read some of the sectors near the center of the disk. After} playing around with it a bit more, I can get it to read almost the whole disk properly.When I try to read in a sequence of} sectors starting at sector 500 (remember that there are 720 sectors in all, on 40 tracks), I can see the head step toward th}e center of the disk track by track - until it gets to the end of track 37, when it actually steps *back* by one track (to 36})! Then it fails to read the sector, and the head goes back to track 0 to reorient itself, and it goes out to track 38 as it} should. Does anyone have any idea why it does this? What do you do to fix this?The other thing I'm worried about now is }*writing* to disks. While my drive might be able to write sectors (I haven't tried yet), it is likely that no other disk dri}ve will be able to *read* these sectors (except for my drive).So what I'd like to know is, is a head alignment based solely} on the position of the track 0 sensor? Do you need an oscilloscope to 'center' the sensor? Is there hope for someone withou}t an oscilloscope to do this? Any references to technical documents, personal suggestions, helpful hints, or any comments, a}re welcome (and thanks in advance!).Jean GouletCC:POEHLANDSubj:1050 Drive AlignmentIn IA8V91#84 AKH104@PSUVM (sure w}ould like a name there) suggests downloading the 1050 drive diag prog from compuserve & use the software to align the sensor.}I was unaware the software was available online, but I do agree with this suggestion. I had occasion to use the diag progr}am this past weekend (before the fire) & saw that sensor alignment didn't require a scope. You just move the sensor around u}ntil it says OK. I've never had occasion to use it, as I always made ascoremark first.I think it will work, but it's tedio}us. Mostly because the sensor invariably ends up moving while you're tightening it down If I aligned a sensor that way, I wo}uldn't trust the drive until it had passed the 10-min burn-in test in the diag prog, plus also had passed compatability tests} with at least 2 other known good drives.The diag program is probably worthless if you only have one drive, & that's the on}e that needs aligning. You need at least one known good drive to load in the the test program. Then disconnect the good dri}ve & boot up the misaligned one to do the job. If the bad drive is already pretty close to correct alignment you might luck }out & be able to load the test software with the bad drive.I got the diag prog some years ago from B&C. It might also be i}n the 8bit library on GEnie.About the time I was fighting the fire in my house Jean Goulet sent me email expressing concern} about the drive in question being equippeed with U/S Doubler & noting the drive already had a Tandon mech. (Sorry for the d }elay, I've been distracted the past few days (!))I'm not 100% sure of this, but I'll take a stab at it. If your original m }ech was a Tandon & you replace it with a Tandon, no problem, the U/S-D ROM will work fine. The only thing you need to concer }n yourself with is the RPM adjustment on the new mech. The RPM.COM utility in SpartaDOS is just fine for this. (I also use  }the RPM utility in DOS 2.6f, but Sparta's is better.) The RPM adjustment screw is right in front of the area in the rear of  }the drive where all the connectors plug in, near the 2917 tachometer chip.*** NEVER *** attempt to adjust ANY of the pots u}nder the RF shield!!!If the original mech was a WST type, the drive is equipped with U/S-D, & you plug in a replacement Tan}don mech, my gut feeling is that it should still work, but since I haven't done it myself I won't swear to it. You'll still }need to adjust RPMs on the new mech. The 1050 diag software doesn't work on 1050's containing U/S-D. If you want to run full} diags on a U/S-D drive, you have to pull out the ICD chips & replace the original chips. If there was a jumper change when t}he U/S-D was installed, you have to desolder the jumperts & put them back in their original positions. Fun, fun, fun!Of co}urse, if you trashed the original chips, or failed to note the originl jumper configuration, you got a hell of a headache.I} was in the process of investigating the ROM/jumper situation the weekend of the fire.

It also has polarizing filters and some other stuff, including a te!)}st tube I think for shining light through chemicals. This tells you something about the properties of the solution but I am !*}not sure what. It also has a cartridge and lab manual.It will show as a percentage how much light is reaching the sensor. !+} It is quite sensitive. The lab manuals have all sorts of experiments and stuff you can do with the different sensors. I th!,}ink the light module will let you record light and temperature data simultaneously. There are some great ideas for science p!-}rojects in the lab manuals.. I think two temp. sensors or two light sensors could be hooked in at once. The manuals give y!.}ou the program code needed to make your own BASIC programs to read the differentsensors. When I brought the lab kits home f!/}rom the show my uncle was very interested in the temp sensor because he works for a factory which among other things plates p!0}arts for GM. They use temp. sensors alot to monitor the plating baths and stuff.Thermistors could be bought but would hav!1}e to be calibrated and I don't know if what would need to be done to treat them so they can be dipped in solutions.

I guess I can begin my "remember when" story.I saw9} an add for An Atari 800 in print long before I actually saw the computer. There used to be a high tech store called Chafitz9} in the Washington, D.C. area that only sold high technology products. They were passing out literature on the Atari 800 an9}d 400 about a year before they ever showed up in the store.I wished I had kept the flyer. It pictured a businessman wearin9}g a suit carrying an Atari 800 up to his office. The computer sounded impressive as it came standard with 8 KB of memory and9} was expandable to 48 KBytes of memory.If I remember correctly, the Atari 800 was introduced at about $1000.00. There was 9}a game pack available that included two joysticks and the game Star Raiders. This was about $70.00.There was a $99 cassett9}e. I don't think the 810s were in the stores yet. At nearly $800 each, I couldn't afford one anyway. There was also the op9}tional basic cartridge.I bought the Atari 800. I had owned two 6800 based computers that bit the dust prior to buyingthe 9}Atari. For over a year, I only played the few cartridges and tape based games I had and practiced learning BASIC.I had alw9}ays been interested in the technical side of computers. The Atari was the first computer that really did anything but allow 9}me to hack with computers. I think that anyone that purchased computers in the 1980 to 1981 time frame remember computers pu9}rely as toys. There was no serious purpose for them. They were not the "productivity tools" they have become. Back then, 9}computers were their most pure, they were there solely for fun and experimentation.When I met my wife, I told her that I ha9}d a personal computer. She was a mainframe programmer but had never seen a personel computer. She said that she had heard o9}f them but had never seen one.I told her that I would loan her the computer to try out. She took it home with a copy of Sp9}ace Invaders. The next morning, she called me and told me she had stayed up all night and wasn't going to work. I think I k9}new then that we were ment for each other.I wore out joystick after joystick playing Missile Command and Star Raiders. Abo9}ut 25% of myyearly income had been invested into the Atari. I spent night after night playing games, programming and trying9} to understand how it all worked. It is hard to believe how many years when by that I continued use and expand my 800 system9}. I bought everything from the 80 col. boards to expanded memory cards. I bought double density drives and even double sid9}ed drives. I set up a BBS once. My wife and I even started a software company XLEnt Software, to share our fascination with9} the Atari computers with other Atari fans.I soon realized that Atari owners were different from other computer owners. At9}ari had always neglected it's customers and software vendors were slow to recognize the Atari as an equal to the Apple II. D9}espite this, we knew we had a better product. We knew that our computer had custom designed graphics and I/O chips that were9} missing in other computers. The Atari's custom chips gave the Atari a personality that was missing in the other computers. 9} The Atari's faster game action, programable character sets and various graphics modes, provided the patient hobbiest with ho9}urs and hours of challenges. Hell, we weren't even limited by graphic modes, we had display lists.When I first bought a co9}mputer, I had this sense of urgency that I was too late. I had read about all the wiz kids that were even younger than me th9}at were making a fortune in computers. I was 26 and I felt like it was too late for me to catch up to these 24 year old kids9} that already knew so much more than I did. Besides, they all seemed to be so much smarter than me anyways.Over time, I be9}gan to assume a confidence about Atari. It was no longer enough to play. I wanted to evangelize. I went into business sell9}ing many high tech products. The store I had sold projection TV's, laser disk players and high fidelity equipment. We also 9}sold Atari computers, printers and floppies. I sold enough floppies in those days to pay the rent. (Floppies were $3.50 eac9}h then).Over time, I was forced to offer new computers. I started with Apple II clones and moved up tothe Columbia which 9}was one of the early IBM PC clones. All along, the Atari 800 remained my personal computer. I wrote my proposals, resumes o9}n the Atari. I wrote articles and typed letters. I learned spreadsheets and databases on the Atari. I learned my first str9}uctured language, Action which was similar to a cross between C and Basic. I learned the joys of telecommunications and the 9}pricipals of D/A conversion.There is much more I could tell but I will skip to the end. In all these years, I have left a 9}Atari 8 bit computer hooked up. The original Atari 800 has been packed away. It will likely never be sold and may never be 9}used. I may pass it down someday but it will remain my most "personal" computer.My five year old used to turn on the Atari9} 8 bit and simply type letters on the screen. She'd call us to the screen and show us that she had typed her name. My wife 9}dragged out a box of cartridges. I had collected about fifty Atari cartridges over the years. My daughter has tried every g9}ame. She rushes to the old computer every night to play her favorite games. Recenly, our Thai exchange student has joined m9}y daughter in playing games. They will sit and challenge each other to game after game of Galaxians, PAC MAN and Centapedes.9}At night, I am sitting in front of my 80386 based computer with 4 MBytes of RAM. I am cursing and swearing as I try to pic9}k the right font for the paragraph I am about to type. My computer has a fax card, a CD ROM, a laser printer, mouse, scanner9} and many other implements of torture that allow me to maintain the image of professionalism I strive for with my clients and9} associates.Hours go by as I create charts, graphs and graphics to make my point. I am considering buying an even larger c9}omputer. My 100 MByte disk is saturated. I look at the clock and see that it is 3:00 am. I notice that I am not the only o9}ne awake. I see a light from another room. I walk towards the light and see my wife sitting with joystick in hand. She is 9}playing with the Atari.I remind her of the time and go back to finish my report.e sitting with joystick in hand.

This venue has established itself as the main show for Atari 8-bit computers. It isE}, in fact, a general computer show, and electronics fare. But, the Atari 8-bit dominates the show.I must admit that I didn'E}t get much time at all to look around. I was too busy on my own stand (thanks to those who came and supported us). We were seE}lling PD, used commercial software, used hardware, and Digi-Studio. Many people came to visit us during the day.Other than E}us, there were the usual Atari exhibitors, as well as a few new ones. Page 6, Micro Discount, and BaPAUG/Gralin were all therE}e as usual.Page 6 was selling its huge range of software and books. Page 6 are at: Page 6, PO BOX 54, Stafford, ST16 1DR.E}Micro Discount was by far the most popular stand (as usual!). It was crowded for the most of the day, and not suprisingly! HoE}w about a 400 for 3quid?! Derek had loads and loads of books/software/manuals as well. How about the complete Technical ReferE}ence Notes for a quid, or De Re Atari for a fiver?! Loads of Field Service Manuals were also available at a quid each. Micro F}discount are on 021-353-5730.BaPAUG/Gralin were selling there usual stock items. Colin was showing off his 1400XL (I even gF}ot to hold it, for a few seconds!).BaPAUG are at: BaPAUG, 248 Wimborne Road, Oakdale, Poole, Dorset, BH15 3EF.Gralin are atF}: Gralin International, 11 Shillito Road, Parkstone, Poole, Dorset, BH12 2BN.A new face to the show was LACE (London Atari F}Computer Enthusiasts). They were there gettin subscribers to there BOOT! newsletter. LACE also run a PD library of "the higheF}st quality" (so there leaflet says!). They also have a dedicated menu on the City BBS (021-352-1237). They also are setting uF}p there own BBS soon. LACE are at: LACE, 143 Richmond Road, Leytonstone, London, E11 4BT. Tel: 081-960-1605. LACE were going F}to have an advert on this issue of the News-Disk, but failed to get it to me by the time I specified (tut tut Simon!).Bill F}Sutton (Late of XL/XE Alive) was there selling some reconditioned hardware and some software. He also had disk notchers at 2.F}50 each. Haven't seen those for a while! Unfortunately, I have no idea what address or phone he is operating out of now.TheF } rest of the show was taken up with other weird and wonderful computers, like the TI-99/4A, et al, and electronics and radio F }enthusiasts. Lots of bargains to be had here too.As usual, AMS was great. Lots to do, and loads of bargains.

But, getting to Stafford was not as easy as we had hoped. 30 secoF }nds onto the motorway out of Doncaster, we had a bit of trouble with the police! A police land rover started flashing its ligF}hts. We thought "it can't be us, let's drive on". So we did, and in fact overtook it! Then the lights started flashing again!F} "It can't be us, we thought". Then it over took us, and stopped us. Yikes, I thought! We got severely told off for driving wF}ith full-beam headlights on. I would just like to thank that policeman for being so lenient! We may never have got past DoncaF}ster if he hadn't of been!!I would like to thank Mike Blenkiron, Mark Keates, Paul Saunders, and William Todd for helping oF}n the stand all day long, under extreme pressure and for no pay!, Mark Keates, Paul Saunders, and William Todd for helping oDA  <DMGETA6;@(,6-@&&6.hhEhDJ}hIhHhhB V` --@@ D:PLAYER.OBJQ)@)@*)@7)@D)@J}Q)@ @@,)@A5%,6-%@ @(8@8@@J} D:ISSUE4.SPL*776-?:C:,<@$AV<@ $AV<@,+@2RR6-?:A6<@<@$AJ}V<A$AV<<<,d+@%@n0@x0@@@J}33(@" THE ATARI 8-BIT NEWS-DISK(@ Š/(@/(@ ****************J}**77(@& 1050 DISK DRIVE atari hard disks44(@# AMS5 SHOW REPORT digi studio!!(@J} $$(@ ******************-@A  % D:MENU.BAS D:COVER.BASHv  +AR@CC(;This brief introduction will now appear on all issues.--(%-----N}--------------------------------(rr(iFor the purpose of reading text files,a program called XR40.OBJ has been supplied.N} This also has a DOC2HH(@ file called XR40.DOC which explains how to use this program.7(<mm(dXR40 can be run frN}om the menu, after pressing Y when asked if you wish to turn off Basic.

Please try and take a little timeXOAtari 8-bit News-Disk Issue 4.------------------------------Editorial by Dean Garraghty.----------------------------W^o}ell here it is! Issue 4 of the News-Disk. Yet again, it was very difficult to put together. This was because of the old probl^p}em: no articles. You will notice that all articles on this issue have been written by me, or have come off the newsnet. I rea^q}lly would like to see some articles from News-Disk readers.The initial idea of the News-Disk was to collect articles and pr^r}ograms from a group of users and then share each others work with the others. So far, this has failed.If you don't want to ^s}write an article or program, then why not write us a letter? If you write a letter for publication then please write "for pub^t}lication" at the top of the letter. If it's going to be long, then please send it on disk!I have written an article for thi^u}s issue called SUBMIT.DOC. This tells you exactly how to submit articles. Please read it, and write some articles!!For many^v} of you, this will be the last issue on your subscription. If your subscription number ends in /4 then it's time to re-subscr^w}iibe! You will have a subscription renewal form enclosed if you fall in to this category. Please please re-subscribe, I need ^x}your support! It would be a waste of time and effort to produce the News-Disk for just a handful of users. I have kept the co^y}st at 4pounds for 4 issues, despite postal rate rises, and stationary price increases. The cost of production is subsidised b^z}y PD sales, otherwise it would run at a loss!Talking of PD, sales have slumped again. There are quite a few new disks in th^{}e library now. See the latest catalogue on side 2 of this disk.Other articles on issue 4 are: 3 articles on aspects of the ^|}1050 drive, an article on rare and long gone hardware, all about hard disks on the Atari, a nice story about an Atari die-har^}}d, a show report of AMS5, an article by on Digi-Studio (including behind-the-scenes details!), an article on AtariLab, and po^~}ssibly more, depending on how much disk space is left after writing this!I have also put a couple of PD games on. These are^} DUNGEON.COM and CLOWN.COM. There is also a little demo by Mark Keates called SERVANT.COM. I have had to remove the DUP.SYS f^}ile from this disk to fit these on.And that's it for this issue. Keep those articles coming, keep those PD orders coming, a^}nd please re-subscribe if you need to.Thank you for your support!Dean Garraghty.24 Jan 1992. those PD orders coming, a\cThat long-gone and rare hardware.Article by: Dean Garraghty. Many newer Atari users won't know about some of the oldb}er hardware that was once available. Also, some old-hands may not know about some of the rarer hardware, some of which was neb}ver released. This article will discuss both rare and old hardware. It is going to be very difficult to split thib}s artcile into 2 sections: old hardware, and rare hardware. In some cases certain items could be classed as both. So, this isb} what I've done: the old hardware section will talk about old hardware that was available in the UK. The rare hardware sectiob}n will talk about hardware (old or new) that was either: available in the States but not the UK, or not available at all!Sb}ection 1 - old hardware If you own a XL/XE machine then it's possible you won't have used, or even seen, a 400 or 800 b}machine. The standard 400 didn't have a real keyboard. It was a membrane (or touch pad) keyboard, and very difficult tob} type on! It only had 16K of RAM, and so it wasn't really feasable to use it with a disk drive. They were quite large machineb}s, made even bigger because they had a cartridge lid, which had to be lifted up to put cartridges in. The 400 had a built-in b}TV lead, and no monitor socket. The quality of the picture and sound was awful. Also, it didn't have Basic built-in as on theb} XL/XE series, so you had to plug a Basic cartridge in. The 400 had 4 joystick ports, for those old 4 player games! But, for b}all its "faults" this was a nice sturdy machine. The standard 800 either had 16,32, or 48K RAM. Extra 16K cards were slb}otted into sockets under a cover at the back of the machine. The 800 had a GREAT keyboard, the best of any of Atari's computeb}rs! Ask any old-hand and they'll tell you the same! The 800 also had no built-in Basic, but did have 4 joystick ports. It alsb}o had a monitor port. That's got the old computers dealt with, so let's go on to talk about what peripherals were availb}able for use with them. If you wanted a datarecorder, then you had to get a 410. These were quite bulky, but sturdy. Thb}ere were 2 different 410s released. If you wanted a disk drive, then you needed an 810. These were HUGE beasts, and coub}ld only hold 88K a side! There were 2 different versions of the 810 (well, there were more than 2, but the others were operatb}ing differences, which are too technical for this article). One had a Tandon drive mechanism. Here the disk was just entered b}into a slot, and a latch brought over the end of the disk. The other types had a MPI drive mechanism. Here there was just a lb}arge box shaped hole at the front. The disk was pushed into the middle, and then a large door slammed down to cover the hole.b} A very weird drive! The 810s were not exactly quiet either! If you wanted a printer, then you had a choice! You could b}have the Atari 825 80 col. dot-matrix. This was very strange, in that it didn't use the standard Atari serial socket. It needb}ed an 850 interface to work. Then there was the 822 40 col. thermal printer. What a weird looking device that was. It was parb}t metal and part plastic. They were quite small, and very quiet in operation. Then there was the 820 40 col. I think this wasb} dot-matrix. This was also a strange looking thing. It looked like an 810 drive with a hole cut in the top for the paper to cb}ome out of! I've only seen a photograph of one of these, so I can't really comment too much on them. I'm not exactly sure wheb}ther or not they were actually sold in the UK. Atari also had other hardware available back then, like the 850 interfacb}e which supplied parallel and serial ports for printers and modems. They had a modem of their own: the 830 acoustic modem. I b}don't think this was available in the UK.Section 2 - rare hardware Some items of hardware were only sold in the Stb}ates, and others never made it out of the Atari workshop! Atari had a far wider range of computers than many people thib}nk. We usually talk about the 400, 800, 600XL, 800XL, 65XE, and 130XE. But there are others, some VERY strange! One youb} may have heard of, is the 1200XL. This really is the "black sheep" of the Atari family. It was a pre-600/800XL computer. It b}had the silver function keys along the top of the keyboard. As well as the OPTION, SELECT, etc. keys, it also had some extra b}function keys, and a couple of LEDs up there! It is probably the least compatible of all the Atari machines. It had no in-buib}lt Basic. It had 64K RAM. Then there is the 1400XL. This beast had a built-in modem and speech chip, along with associab}ted device drivers. A very odd looking thing, but with a nice keyboard (managed to see one of these things thanks to Colin Hub}nt at BaPAUG). There was also a 1450XLD. This was basically an 800XL with a double sided disk drive built into the backb}. VERY rare machine. Atari also released a 65XEM. This had 8-channel stereo sound. It was compatible in every other wayb}, but the sound had to be specially programmed. Atari was planning on releasing the XEP portable Atari, but pulled out b}before production. Atari may well have had more computers than this, but I know of no others. Readers of Mapping b}the Atari, will have read that Atari meant to release the 815 double density disk drive, but it was withdrawn from productionb}. One of the things that never got past Atari's door! However, you may have read on past issues of the news-disk that the 815b} was actually a two 810s in one case. No idea which is true! Also on disk drives, Atari experimented with the 1050, andb} came up with the 1055. This had a 3 1/2" drive mechanism, which was never produced. I have heard that the XF-551 driveb} was developed as a 3 1/2" drive. This is why the circuit board is crammed at the back. The big space left was for the 3 1/2"b} drive mechanism. Other bits and pieces never released in the UK are: the 835 modem, XM-301 modem, 1030 modem, XTC201 cb}olour thermal printer, XDM121 daisy-wheel printer, 1025 printer, and possibly lots more things! It is very possible thab}t a lot more hardware than that listed here never made it into the shops, but Atari was very secretive (and still is!), and sb}o there's no way we'll ever find out!
