Managing Editor, and a m[}ember of OL' HACKERS. AGEING? Most 1050 disk drives by now are getting older and showing their age. Performance\} signs of age are occasional failure to format a disk, failure to read a good file, noise and sometimes inser]}ting strange symbols into your text. Before you make the upgrade you might want to check the condition of your^} power supply. Read the section DEVICES NEEDED and section VIII, VOLTAGE MEASUREMENT. This will give you a goo_}d idea of the condition of your power supply and if the upgrade is needed. Once you have made the upgrade th`}e 1050 will be just like new again, very reliable, quiet and will last you a very long time. There are two types ofa} 1050 disk drives. One is the TANDON and the other is the WORLD STORAGE. They are identical in most respects andb} are upgraded the same way. LABOR OF LOVE You must have skills in soldering and unsoldering. Budget about 4 hourc}s for each drive upgrade. This is a labor of love and I would hesitate to impose on a friend with this project. d} The description of the parts position is always with the disk drive front facing you. The Printed Circuit Board we}ill be referred to in this article as the PCB. DEVICES NEEDED There are a few devices that you have to makef} yourself. You need TIE POINT EXTENDERS to read the voltages. You cannot reach the tie points otherwise easily. g} Take a 5 in. black piece of thin solid hook up wire. Remove 1 in insulation from one end and 1/4 in insulation frh}om the other end. Take the end with the longer exposed wire and wrap it about 5 or 6 times around a sewing neei}dle so it forms a little spring. You will now be able to slip this over the tie points on the PCB and be able to measure j} the voltages easily. Make two more exactly the same way with different color wire. You will also need 4 SPLk}ICERS. Take a very thin copper wire and wrap it about 10 times around a darning needle so it forms a spring about 1/<}짠򠠠m}Πռ Š n}ϠȠҡ ۱ Exit To Basic ۲ Exit To Dos ۳ Printer Config o}ԠSPACEBARϠΠà͡ READ/PRINT ALL p} NOTE: This DISK ERRORS may contain .BAS DD III Review & .COM files.

LOUIS Repr0}inted from ACE ST. LOUIS by the OL' HACKERS AUG. =-=-=-=-=-=-=-=-=-=-=-=-=-=-= (Editor, though this is a reprint 0} it is such a valuable review of a FANTASTIC UPGRADE of what was already a great program for the 8 BIT, that its0} worth reading or re-reading even if you read it before!)Just when I was getting cozy withDaisy Dot II, 0}Roy Goldman's NLQsoftware print processor, along comesDaisy Dot III. It has been releasedin a shareware versio0}n and acommercial version which costs $25.00. Share version does lack the abilityto designate font changes from y0}ourdocument and it will not work withSparta X, but it is complete enough toallow me to do this review.You are lookin0}g at the most impressivenew revision found in DDIII. Thisfont and others like it are theclosest your 8-Bit 90} pin printer canget to "Point" type DTP fonts that Ihave seen to date. The next good newsis that you no longer have t0}o formatyour margins with your word processorand "Print" your file to disk alongwith its embedded commands. DDIII0}will take a straight ASCII file, (nota saved, tokenized file) and neatlyformat its own margins. The resultingprintou0}t saves you that frustrationyou experienced in DDII when your textdidn't quite center. You can stilluse embedded 0} formatting commandswithin the body of your text tocenter, expand print, block left, etc. It has new commands0} which handlehanging indents and hard and softhyphens. DDIII supports Epson andcompatibles, Star, Blue 0} Chip,Mannesman Spirit, XMM801, andProwriter.There are a few points about DDIIIwhich I found to be quite f0}rustrating. The Print Processor does not includea number of the handy items found inits predecessor. Among these are 0}theability to center and block left orright directly from the program.Processor's menu no longer controlsthe0} amount of vertical space betweenletters, either. If you are using a"handwriting" font, which requires 0spacing, y0}ou must include an imbeddedcommand, or re-customize your defaultsfrom the basic program. The latterchoice involves 0} quitting DDIII,rebooting your disk with basic andrunning the customizer program .Sadly, it will no longer0} include 62sector pics files, so Chris Wareham's"Billboard" dump will now go unused.DDIII includes the most elaborate Fo0}ntEditor that I have ever seen. It hasmore editing commands than mostdrawing programs. Scroll thesecomma0}nds through a handy window torefresh your memory or use the docsprovided. You may never need it,however. Ele0}ven fonts are included ondisk, and if you send for the "fancy"version you get many many more fonts.I understand DDIII 0} will accept mostDDII fonts, so don't throw away yournifty club disk. DDII, however, willnot return the favor.If th0}e included fonts don't satisfyyour needs you can go to the FontUtilities section, use "Magnify" andenlarge any 0}font up to 4 times itsoriginal size. Font Utilities willalso italicize a font OR convert anystandard Atari font 0}to DDIII format.Note: Magnified fonts may be too largefor the font editor. Meanwhile, back at the PrintProces0}sor, we need to examine a fewmore things DDIII does. Both thePrint Processor and the Font Editormust be cu0}stom configured fromindividual basic files. The Fontcustomiser is a simple one shotprocess that you ne0}ed not repeat.With The PP Custom.bas file, youdesignate your printer, characterspacing, horizontal line 0}spacing,margins etc. The difficult way tochange your text is to go back to thisfile and RE config every time. Avoid0}it if possible. Set your favoritegeneric defaults and then use therelatively simple DDIII embeddedcommand0}s from your original text tochange or refine them. The defaultsare in 40ths and 72ths of a inch! Youcan regulate sp0}acing to the last pixelwith parameters this exact, providedyou can understand them. Luckily Igot help VIA BBS fro1}m a very brightand patient expert in Columbia. JohnMcGowan, teacher, math guru, gradstudent and absolute geniu1}s withTextpro, DDIII and fonts in generalexplained DDDIII so that even I couldunderstand it. Note: The customizer1}prints your choices to Print Processorand then has the annoying habit ofdefaulting back to its originalformat, 1} so be sure to write down whatyou did to your program. Although notvisible, the commands are still inthere.Help is1} on the way for you picturefans! Disappointed with the currentlack of pics, John got busy andfigured a way 1} to incorporate PrintShop icons into magnified fonts. Yes,you can load any number of individualfonts which have up to 11}0 or more P.S.icons hiding in them. He wrote aconversion program, arc'd it with ShopTool P.S. to DOS 2 converte1}r, anduploaded it to Gateway BBS, along withinstructions and Textpro macros to aidyou. Its real value is to registeredo1}wners of DDIII because it allows youto change fonts (aka icons) from yourtext file. The P.S. icons can becentered 1 } or blocked left or right.You can also make a decorative rowsimilar to "Tile" option in PrintShop. I will wr1 }ite more on this nextmonth after my commercial versionarrives. This icon perk is best usedby people who re-use par1 }ticular iconsto identify parts of a newsletter orflyer. It's not for you "6000 iconsfor any occasion" fans.I cannot1 } overstate the value of DDIII. You can compose flyers with thelarger fonts and write newsletterswith the smaller1 } ones. Currently I amearning mucho brownie points bywriting my Mom with this "easy toread" font.

During that time, my entire house was painted, including closets, which required the complete disas5}sebly and packing of both my Atari and my MS-DOS systems. Upon re-assembly, the Atari system, with all of its 5} separate units and interconnections, went together relatively smoothly. I had to resolder a ground 5}lead in the one piece of handmade-cable -- the one that gives me null-modem from my Atari to a switchbox, and th5}en on to my DOS machine. The DOS machine required a LOT MORE TIME to put together, even though almost5} everything is contained in one box. It's a long story, but take my word for it; the Atari is simpler to re- assemb5}le and check out. On to the reviews ... Update Atari for May, 1993. This is over a year old, but contains a 5}GEORGE IKEN article about Atari graphics converters that includes handy descriptions of all of the graphics5} modes. It also describes items in the H.A.C.E. library that I didn't know existed. They allow conversion from 5}file formats found on other machine platforms. (FR)ANTIC for May, 1994 -- BOB HUDDLESTON wrote an enchantin5}g article about (simulated) flying, using the FS-2 Flight Simulator from Sub Logic. Russell Stowe begins a serie5}s on disk drive maintenence and a list of "NEVERS" that we've all violated from time to time; tempting the appearanc5}e of the Murphy demons in so doing! RUSSELL STOWE gives us a type-in program for formatting disks from BASIC.5} There's also another type-in, reprinted from P.A.C.E. (March, 1994) that puts the hands of a clock on the sc5}reen and rotates them backwards! Who says time go backwards? (grin) The PACEsetter for May, 1994 -- RON FETZER's arti5}cle, Life Insurance for your DISK DRIVES, is reprinted in this issue. There is also a reprint of a review of Broderb5 }und's Art Shop by FORREST A. BLOOD IV, which originally appeared in the JACS Newsletter of June, 1986. Th5!}ere are also the usual puzzles and jokes. An always interesting newsletter! The SAGE Scroll for May, 1994 has an inter5"}esting comment by editor JIM FOUCH regarding the death of Commodore and its relation to Atari. There are a5#}lso reprints of Requiem For The ATARI 8-Bit, by ROBERT ARISTO of MVACE, which was first seen in the MVACE News of April 5$}1989 and later reprinted in the LVAUG News of December, 1991; and of What A COMPUTER HAS DONE TO MY 5%}HOUSE by DENNIS KLINE, (an OHAUG member) and reprinted from OL' HACKERS newsletter of March/April 1991 after submission5&} to SAGE via WNYAUG. Nybbles and Bytes for May/June, 1994 -- DALE WOOSTER gives us his thoughts on TextPro 5.1, A5'}C Magazine, SpartaDos 3.2F, the R-Time-8 "2000 bug", and Prism Studio, all in separate articles. JOHN COLLIN5(}S has an interesting editor's column that mentions a variety of important items. The DACE Desktop for May/June,5)} 1994 - - includes a mini-review of Djinni, an attempt to bring Aladdin-like navigation to those of us who5*} use our modems and subscribe to GEnie. The S.L.C.C. Journal for June, 1994 - - contains a three-page listing of their5+} library additions through June. OHAUG is listed as a source of many of these fine disks. The text of BOB BRODIE's r5,}esignation letter is reprinted. The PACEsetter for June, 1994 -- A reprint of BEN POEHLAND's response to RON FETZ5-}ER's article on disk drives is reprinted. PACE also has reprinted Ron's writeup of his program, Treasur5.}er's Report, with a note that the program can be found in the PACE library, and a great program it is too! Nybbles and5/} Bytes for July/August, 1994 -- There is a reprint of an article by STEVEN BERG, from the ACE (Eugene, Oregon -50} Dec/Jan 1983) Newsletter which describes and gives measured drawings of a desk that can be constructed from one 51} sheet of plywood and which will hold an Atari 8-bit system. It's similar to the commercial desk I've used for 52}my system since about the time of the original article. JOHN POWELL and DALE WOOSTER collaborated on an arti53}cle describing how Nintendo Controllers can be modified to work with Atari 8-bit computers. The entire ATAR54}I Affairs column from May/June, 1994 XIO3 is reprinted.

THE FIRST LOG ON The first E}time you log on to a BBS, most sysops like to receive FEEDBACK from you. Introduce yourself, tell aboE}ut your computer system and if you are new to modeming, tell the sysop. Most will be happy to give you any help you mayE} require. BE HONEST Be sure that all of your information given at log-on is correct. Many sysopsE} will call you by phone to be sure you are who you say you are. Unfortunately there are still a few kiddies aroundE} that like to log-on BBSs and raise the devil. That is why passwords and validation are necessary. WATCH OUT FOR E}"CALL WAITING" If you have CALL WAITING on your phone system, disable it to use your modem. CALL WAITING can cE}rash a BBS system. If you cannot disable it, please do not call BBS systems from that phone line. EARN HIGH ACCEE}SS High access, which means lots of time and a high UL (UPLOAD) to DL (DOWNLOAD) ratio, is earned. Most new E}callers will start out with from 30 to 60 minutes. It depends on what the sysop chooses to designate as your time.E} WHATS IN IT FOR YOU? There are many things you can do on a BBS. You can UL and DL files for your computer. YoE}u can go to the message bases and exchange information with other computer users. You may also send private E-ME}ail to your friends. You can play on-line games, take surveys and see the results, read informative material in E}the BBS databases or libraries, talk directly with the sysop and even send a file privately to a friend. The moreE} you participate in a BBS the higher your access time will be. CAPTURE THE MENUS AND REVIEW THEM Most BBS systems, E}even those running the same program, can use different command structures. When you are new to a system, it will helpE} you to get around if you capture the menus and peruse them off-line so that it doesn't eat up your on-line tiE}me. A HANDLE IS NOT ONLY ON A CUP! Many BBSs allow you to use a handle which is a nickname you choose for yourseE}lf. You may use your real name if you like. The choice is up to you.

Every now and then I come across something that I think is worthy of repeating, even if, asI} here, I have to type it in myself (ugh) with the hunt and peck style. This article is from the July 1994 issue of THEI} PACESETTER from Largo, Florida. It was written by the editor JEAN BROKAW, and I think it relates to all of us and gives aI}ll the reasons why you should participate in many club activities. With EDITORS LICENSE, I have changed the PACE namI}e to OL' HACKERS. I know that JEAN will not mind. It is herewith reprinted by OL' HACKERS AUG, with permission. J} ================== A DOSE OF P.A.C.E.(read that as OHAUG) by JEAN BROKAW Active participatJ}ion in the O.H.A.U.G. (Ed. insert the name of YOUR CLUB here, or wherever a CLUB NAME fits A.P.) organization is J}a SURE CURE for the following ailments: 1. HYPNO-PROGRAM-ITIS; An insatiable desire for more and more programs. TJ}his is easily cured by making a copy of EVERY disk in the OHAUG (YOUR CLUB) library. 2. NON-COMMUNICATIVE-APHOBIA;J} The fear of having no one with whom to discuss computer progress and/or problems. CURE: Club members eagerly sJ}hare expertise. Attend meetings if at all possible. (Ed. if not possible write a letter to the club, or an article forJ} the newsletter. A.P.) 3. ACUTE-BUDGET-ISM; A condition of contracted purse string muscles. Spending large sums J}of money (Ed. such as buying a P.C. or their programs. A.P.) can be extremely PAINFUL, but there is no strain and nJ}o pain with being in the OHAUG club (YOUR CLUB) member with minimal yearly dues. 4. FELLOWSHIP-ABUNDI; Most contagiJ }ous of all, and found at every OHAUG (YOUR CLUB) meeting, or when reading the club newsletter. A good time is J }guaranteed to all! 5. EXPANDING KNOWLEDGE-ITIS; The acceptance that the world and the youngsters are learning J } new pathways to knowledge, and the REAL FEAR is that you will be left behind. CURE is to join a COMPUTER club, liJ }ke OHAUG! 6. COMPUTER-PHOBIA; The fear that if you hit the wrong key, the computer will blow up in your face. CURE J }is to sit in front of the computer and try everything, (AFTER you FIRST make a COPY of the program) and to find outJ} that the computer still works. 7. THE I'LLNEVERLEARNITIS; The unhappy thought that you are more stupid than the other J} CLUB members. CURE is the realization that everyone was just as stupid when they started. <>ther Hx 2400 BAUD modem In very short order, you will save the original cost by saving time while on the BBS, specially when yoF}u are on a long distance BBS downloading new programs.ANOTHER WORTHY INVESTMENT! Unquestionably, It pays to invF}est in a good surge suppressor and telephone line spike protector to protect your equipment from lightning strikes anF}d electrical surges. They are not foolproof, but it helps. When thunder rolls and lightning is near, the BEST anF}d ONLY REAL PROTECTION is to unplug your system and disconnect your modem from the telephone jack. Getting hit is EXPF}ENSIVE and will probably fry your equipment. Being forewarned is to be forearmed, and save MONEY in the long run! F}DONT BITE THE HAND THAT FEEDS YOU! Do not drop carrier if you can avoid it. Dropping carrier means you turn off yoF}ur modem and get a quick disconnect from the BBS. It can play havoc with a BBS and the sysop will most likelyF} take action if you continue this practice. Do a normal log off. Remember, you are a guest and the sysop is aF}ying the bill! WHY A BBS? The main reason for the existence of a BBS is for information exchange. Upload somethinF}g to share with other users, participate in the message bases. If you have a problem with hardware or softwarF}e, it is likely that you can get an answer by posting in the message bases rather than asking the sysop. UsuallyF} you will get more than one answer.

Port 1 of the 850 interface module has the following pin assigN!}nments: Pin Function --- -------- 1 Data Terminal Ready (DTR) output. 2 Carrier Detect (DN"}CD) input. 3 Transmit data (Xmit) output. 4 Receive data (Rec) input. 5 Signal ground (GND). 6 Data Set ReadN#}y (DSR) input. 7 Request to Send (RTS) output. 8 Clear to Send (CTS) input. 9 no connection. To connect N$}the Atari 850 port 1 to a modem requires a cable with a male DB9 connector at the Atari end and a male DB25 coN%}nnector at the modem end. The wiring is as follows: Atari end Modem end --------- ---N&}------ 1...............DTR...............20 2...............DCD................8 3...............Xmit...............2 4..N'}.............Rec................3 5...............GND................7 6...............DSR................6 7.............N(}..RTS................4 8...............CTS................5 WHATS NEEDED: To connect the Atari 850 directN)}ly to a PC without going through a modem requires a null modem connection. If you have the above Atari modemN*} cable and a modem cable for your PC the easiest thing to do is to buy a Radio Shack Null Modem adapter and simN+}ply connect the two cables together with the adapter. You may need a Gender Changer adapter in order to make the cN,}onnection because the Null Modem adapter normally comes with a male and a female end while two female ends are required.N-} MAKING YOUR OWN If you want to make your own null modem cable you will require a DB9 male connector for thN.}e Atari end. The PC end is normally a female DB25 or a female DB9 connector. If the PC has a 25 pin connector the wN/}iring is as follows: Atari end PC end --------- ------- 1....DTR...................N0}DSR....6 2. DCD DCD |.8 6.|..DSR...................DTR...20 3....Xmit..................Rec....3 4...N1}.Rec...................Xmit...2 5....GND...................GND....7 7....RTS...................CTS....5 8....CTS..........N2}.........RTS....4 Note: Pins 6&8 jumpered at PC end Pins 2&6 jumpered at Atari end WHAT IF? If the PC haN3}s a 9 pin connector the wiring is as follows: Atari end PC end --------- ------- N4}1....DTR....................DSR....6 2. DCD DCD |.1 6.|..DSR....................DTR....4 3....Xmit..N5}.................REC....2 4....Rec...................Xmit....3 5....GND....................GND....5 7....RTS..............N6}......CTS....8 8....CTS....................RTS....7 Note: Pins 1&6 jumpered at PC end Pins 2&6 jumpered at Atari enN7}d DO YOU NEED ALL THESE H/S LINES? Depending on your software, you may not need all the handshake lines. You N8}may be able to get away with as few as three wires (GND, Xmit-Rec,and Rec-Xmit). However, if your PC software N9}makes any DOS calls to the comm port, you will need all the handshake lines. **end** software Lqant to put a little fun in your life...reach out...reach out and baud someone! --from an unknown source F;} >> end <} your disk drive is the internal power supply. The power supply is like the heart of a human being that pumps blood to?} the organs. The power supply pumps D.C. voltages to all the I.C.'s and chips. This voltage has to be almost pure@} D.C. If there is a substantial A.C. component riding on top of the D.C. then your I.C.'s get confused and thiA}nk they are receiving information pulses. A.C. or Alternating Current has a high and a low potential just like daB}ta pulses. That is the reason you have to upgrade your power supply to eliminate the A.C. ripple current on top of theC} D.C. voltage. The solid state I.C.'s and other solid state devices will stay virtually like new if they reD}ceive the proper D.C. voltage and are protected from excessive heat. While your disk drive is disassembledE} you should also clean all contacts, read-write head, belts, pulleys and moving components etc. At the end of thF}is article I will give you a list of tools needed, supplies required and replacement components needed, and aG}lso where to get them. FILTER CAPACITORS GET OLD As they age, the filter capacitors in the power supply H}dry out and develop a high power factor. This results in letting A.C. pass through on top of the D.C. voltage. ThI}is voltage is usually called the ripple voltage. Since this is a major overhaul of your 1050 disk drive we are goJ}ing to replace them with premium filter capacitors which are larger than the original, high efficient, hiK}gh temperature, long life types. We are also going to replace the 1N4001 1 Amp. Charge Pump Diodes with 3 Amp. hL}eavy duty 1N5400 Silicon Rectifier Diodes. This will beef up the power supply so it that it is a new heavy duty lM}ong lasting supply. THE JOB STEP BY STEP I. DISASSEMBLY 1a) Turn your drive on its back and with a PhillipsN} screw driver remove the 2 screws in the black front bezel. Then remove the 4 screws in the corners. Slide the top foO}rward and out. Place it aside. 1b) Next we must disconnect all the jacks from the PCB so we can remove thP}e mechanical motor assembly. The motor assembly rests on 4 pins with rubber cushions. Lift the front to see it. In tQ}he front on the right side of the PCB is a jack. Mark it and the PCB with White Out so that you know how to inserR}t it again. Remove the jack. Do NOT pull on the wires but use the body of the jack to pull up on. 1c) In the bacS}k where the power supply is, there is a large jack on the left, and a smaller one on the right. They have to bT}e removed. The left hand jack is really 5 jacks next to each other and they will come out individually. If you look nexU}t to the jacks on the PCB you will see the jack markings. On Tandon drives the body of the jack is also marked. On WV}orld Storage drives the jacks are corrugated and they are not marked. The easiest way to mark where the jackW} belongs is to take a piece of masking tape, write the jack number on it and glue it around the appropriate wires. X} Here are the left handed jacks, front to back and the number of wires they have. J11 has 4 wires J12 has 2Y} wires J1 has 4 wires(motor control) J10 has 4 wires J14 has 3 wires On the right hand side there iZ}s a single jack J15. Mark it and the PCB with White Out so you know how to insert in later on. Remove it also. [} 1d) On World Storage drives there is one more wire, a ground wire, usually purple that is glued with apoxy \}to the heat sink. The easiest way to remove it is to cut it and later on to solder it again when you assemble the]} drive. 1e) You now can lift the motor assembly and remove it. Put it aside for now. You now have only the PCB ^}and the bottom cover. II PCB REMOVAL You should wear a wrist grounding strap (see Tools) or have a grounded sur_}face that you work on for the next steps. 2a) If you remove the 4 rubber cushions on the motor pins it will be`} easier to remove the PCB. On Tandon drives about 2 inches from the front on either side of the PCB there are plasa}tic snap holders that you must push back to remove the PCB. On World Storage drives you also have an additionab}l two snaps in the back of the PCB. You also have 2 hold down screws on the PCB in the back and on on the left frc}ont of the PCB in some drives. You must remove them. The PCB will now come out quite easily. Put the bottom aside d} you will work only with the PCB. III UPGRADING OF THE POWER SUPPLY 3a) As you look at the PCB in the back on the}e left side of the metal heat shield are two IC's mounted with screws and one on the right hand side. The rear left andf} right IC's are the voltage regulators. The left is a 7812 for 12 volts D.C.(Q8). The right is a 7805 for 5 volts Dg}.C.(Q7). Both of these regulators should have a white paste or heat sink compound (see supplies) on their backs. Ih}f they seem to have very little compound on them remove the nut, bend the IC a little forward. Clean both surfaces witi}h 91% Isopropyl alcohol. Put new heat sink paste on them and reapply the nut. This helps dissipate the heat from thj}e IC. The front left IC usually has some kind of insulating material square clamped to its back. This is the TIk}P110 (Q6). Leave it ALONE! 3b) Next you are going to ground the metal case that covers most of the IC's. Cut a 5 inl}. piece of hook up wire. Strip the insulation from both sides. Find another nut that fits over the right side of m} the screw that sticks out from Q7 on the metal shield. Put the wire around the screw and put the second nut on n}top of it. Solder the other end of the wire to the side of the metal cage. This prevents RFI from your drive.o} 3c) Next we desolder the 3 big black filter capacitors C67, C68 and C71. On Tandon drives they have only 2 leadp}s + and -. On World Storage drives they have 3 leads +,- and a dummy lead. You must desolder all of the leads to q}remove the capacitors. I used the SOLDAPULT desoldering tool from Radio Shack (see tools) and found it quite effectir}ve. After the capacitors are removed clean out the holes. To clean the holes put a little solder over it and suck its} out again with the SOLDAPULT tool. The old capacitors were 4700 uf at 35 volts or less. The new ones we will installt} are going to be larger 6800 uf 35 volt, 105 degree C temperature, long life, high efficiency types. 3d) u}Remove the charge pump diodes CR15, CR16. They are in the middle between capacitor C71 and C68. They are clearly mav}rked on the PCB. We are NOT going to desolder them, instead we are going to clip them near the body of the diode so w} we have two leads sticking up for each diode. The new diodes will get attached to these leads. The 3 Amp. diodex}s have thicker leads and would not fit into the holes on the PCB. Besides this is the easier way of doing it. IV INSTALLy}ATION OF NEW PARTS 4a) The first thing we are going to do is install the new 3 Amp. charge pump diodes 1N5400 in z}place of the CR15, CR16 1 Amp. diodes. Cut the lead of each new diode about 1/2 in. from its body and bend it 90 degr{}ees. Take a solder splicer and fit it over each leg of the diode. Slip the other end of the solder splicer over the |} old leads of the diode sticking out of the PCB. The band of the diodes faces right. Solder the connections. Do this}} for both diodes. They both face to the right with the band. 4b) Next take your new filter capacitors, which are ~} not wire lead types, but have snap legs, and see if you have to adjust the legs. They will not fit flush on the PCB bu}t are about 1/8 in. above it. Adjust the legs so they fit into the holes of C67, C68 and C71 and solder them. The ne}gative band faces to the right on all 3 filter capacitors. V CLEANING To clean the jacks contacts and I/O} contacts use CREMOLIN R100 and B100 (See CN Oct. 90 page 24 "THE MAGIC JUICE") or if you do not have it use 91% }alcohol (see supplies) VI REASSEMBLY 6a) Put the PCB in the bottom cover and snap in the plastic reta}iners on the side of the PCB (4 on World Storage drives). If you had hold down screws for the PCB reattach them. } 6b) Put the rubber cushion back on the 4 motor resting pins with the flat side up Before putting the motor assemb}ly back look at the belt on the bottom. Clean it with soap and water if it seems greasy. Clean the motor pulley and} the flywheel with alcohol and reattach the belt. 6c) Take the motor assembly and put it on the 4 pins so they ma}tch the holes in the housing. 6d) Twist the wires around a few times and attach jack J15 on the right rear side. T}wisting prevents RFI. 6e) Attach jack J6 on the front right side. 6f) Attach jacks J11, J12, J1, J 10 and }J14 to their pins on the left hand side. Twist J1 a few times around. This prevents RFI. J1 is the motor jack. }It is sticking out a bit on Tandon drives. 6g) If you had cut the purple ground wire re-solder it and pu}t insulation tape over it. You are now finished with the major part of the reassembly of your drive. Plug the} power transformer in to the drive, turn it on and see if everything is O.K. and the read/write head goes into the p}ark position. VII SPEED ADJUSTMENT Use DOS 2.6f (black DOS) or any other disk drive speed checking progra}m to see if the speed is correct. The 1050 is very stable in this regard and usually does not need to be adjus}ted. The correct speed is 288 RPM for an unmodified drive. The range can be from 280 to 296 without an adjustment. } If you have to adjust the speed look for the potentiometer VR2. It is just to the right of jack J11. It is a small} rectangular block with a tiny screw on top. Use a jewelers type of screw driver to adjust the speed to the right }RPM. VIII VOLTAGE MEASUREMENTS Take the black TIE POINT EXTENDER LEAD that you made previously and slip it over }TP15. TP15 is the ground. It is located in front of C68 and slightly to the left of it. It is clearly marked} on the PCB. to the right of TP15 is TP13. Take the other extension and slip it over TP13. To the left of TP15 is }TP14. Slip another extension over this tie point also. You now have 3 wires sticking out of your disk drive, 1 bl}ack and 2 others. Take your Digital Volt Meter (DVM) or VOM and attach the ground probe to the blac}k extension and attach the positive probe to the extension of TP13. Set the range switch to 10 volts D.C. T}urn on the drive. It should read 4.9 - 5.1 v. D.C. Now attach the positive probe to the extension of TP14. It shou}ld read 12.01 - 12.03 v. D.C. These are not the most important voltages that you will measure. The most importa}nt voltage is the A.C. ripple voltage that is riding on top of the D.C. voltage. To measure the A.C. } ripple voltage get about a .1uf 100v or higher mylar capacitor and with clip leads attach the capacitor to t}he extension of TP13 and the other end of the capacitor to your positive probe. Set your meter to its lowest A.C. r}ange. The capacitor will block the D.C. and will let only the A.C. voltage pass. You should get a reading of .00}1v. A.C. or less. That is what I got. Do the same thing with TP14. That is 1 millivolt of A.C. RMS ripple which is ex}cellent. I think it is even less than what I measured because my probe leads are not shielded. This voltage may be p}artly stray A.C. being picked up by the probe leads. If you use an analog meter you do the same thing. On the A.C.} ripple measurement the needle should not move or barely move at all. The A.C. ripple is the quality measurement} of your power supply. It should NOT have more than .002 v. A.C. RMS ripple riding on top of your D.C. voltage. The com}mand signal to STOP READ on the Floppy Disk Controller Chip WD2793 on pin 27 is only -30 millivolts. If your} power supply had an A.C. ripple voltage of only 11 millivolts RMS which translates into 30 millivolts Peak-to-Peak} ripple A.C. it would be the same amplitude as the command signal and could easily confuse the chip. There ar}e even smaller voltages in your disk drive. You can see why the power supply has to deliver clean D.C. voltages to yo}ur IC's. IX LUBRICATING THE MECHANISM 9a) Use LUBE GEL (see supplies) and with a swab stick (see supplies) th}at is broken in the middle. Apply a small amount on the rails of the read- write head. Smooth it out with the cotton }swab. DO NOT use Q Tips or oil in your drive. Q Tips are glued to the stick and when dunked into alcohol the glue then }will spread over every surface you touch. 9b) Put Lube Gel on all the moving surfaces that eject the di}sk and are rubbing such as the tang that lowers the spindle to the disk etc. 9c) Take the cotton swab and with 91%} Isopropyl Alcohol clean the read- write head. 9d) Rotate the pressure pad about 30 degrees with a screw driver} to expose a new felt surface. The pressure pad is right over the read- write head and holds the disk to the} head. 1/16 in. of felt should be showing below the plastic. If it is worn down to the plastic replace it. You }can get a new one from BEST & CO. 9e) Clean the two I/O connectors in the back and the power supply jack with Crem}olin or alcohol. 9f) To install the cover move it from the front to the back and install the 6 phillips head screws} and tighten them. Your disk drive is now reassembled. Try it out and see if it works O.K. X COSMETIC}S On the back of your disk drive on top of the I/O connectors there is raised lettering. Mask the top and b}ottom with Scotch Tape and take a permanent type black felt tip marker and gently swipe over the lettering. Remove} the Sotch Tape and the lettering will now stand out in black. Mask the lettering on the front bla}ck bezel with Scotch Tape "OFF POWER ON". Also put tape in front and the back of the word "POWER". Take some Wh}ite Out and put a little on a piece of plastic and with a smooth sponge pick up the wet White Out. Gently swipe }it across the lettering. If you mess up you can remove it with alcohol. You now have the raised lettering in white} on the front of your disk drive. Your disk drive is now in tip top shape. It is probably better than when it w}as new. It will work quietly and reliably for you for a very long time. In addition you have improved its appearance}.
