SNAPSHOT is fully compatible with the Ras}mbo RAM upgrade from ICD.Synopsis: SNAPSHOT allows you to-------- have two virtual computer systet}ms in your Atari 8-bit computer at one time.NOTICE: You are using this at yourown risk. Every attempt u}has beenmade to assure the functionality ofthis software. However, SNAPSHOThas only been used with a verynarrow range of v}both hardware andsoftware. Unpredictable results mayoccur resulting in the loss ofdata. Remember to ... ***************w}*************** * Always make a backup copy! * ******************************Send comments, suggestions,complaints, anx}d bug reports to theBBS listed in this documentationfile. If you have a problem withSNAPSHOT, be sure to include thefolloy}wing information: Computerused, memory upgrade used, softwareand type of dos used, peripheralsused, and any other info youz} mightthink useful in diagnosing theproblem.Restrictions: This software may NOT------------ be sold. It may be {} freely distributed as long as this documentation file accompanies the |} software.___________________________________ WHAT IS SNAPSHOT? -----------------Ever wish you}} had instantaneousaccess to a certain utility, wordprocessor, or DOS while runninganother program or DOS? Now youcan, usi~}ng SNAPSHOT.With SNAPSHOT loaded, by simplypressing Shift-Control-1 (i.e.pressing all three keys at once)you can witch }between twodifferent applications in just afew micro-seconds. This is idealfor BBS operators who want to havea program li}ke TextPro available ina moments time, and then switchback to their BBS. And you can dothis without taking the BBS down!}You actually have two virtualcomputers residing in the samesystem at the same time! You arelimited only by your imaginatio}nand the RAM size of your machine.Well, not really. There are a fewlimitations to SNAPSHOT.You will probably run across }someprograms that are incompatible withSNAPSHOT. These incompatabilityproblems will probably be lessenedwith subsequent r}eleases ofSNAPSHOT. The way to be sure thatyou are using the most recentversion of SNAPSHOT is to call theCloser To Home }BBS at 419-368-4413.This is the official support BBSfor SNAPSHOT.Any questions, comments, andsuggestions concerning SNAP}SHOT arewelcome. Just send them to theSysop there (me), and I'll be sureand give you a speedy reply.___________________}________________ DIRECTIONS FOR USE OF SNAPSHOT ------------------------------First format a blank disk and thenplac}e on it the DOS of your choice(Atari DOS 2.5, MyDOS 4.5 or SpartaDOS 3.2). Then copy the files"SNAPSHOT.COM" and "SOFTBOOT}.COM"onto your new disk. This will nowbe your SNAPSHOT working disk.After placing your SNAPSHOT disk inyour drive and bo}oting DOS (withoutBASIC), just load SNAPSHOT as youwould any other normal .COM file.You will see a short messageprinted t}elling you that SNAPSHOThas installed itself.You are now looking at the first oftwo virtual systems living in yourcomput}er! Now, load something newin, like your favorite utility.When you have done this, replaceyour SNAPSHOT disk in your drive}and press and hold [Shift-Control-1](press all three keys at the sametime) until you hear a buzzingsound coming from your} speaker.This buzz is made by SNAPSHOT tolet you know that it has acceptedyour request to switch to thesecond system. Whe}n you hear thisbuzz, release the keys you arepressing or SNAPSHOT may instantlyswitch back to the first system.After thi}s you will be looking atthe second system's screen. Itlooks just like the same screen yousaw right after loading SNAPSHOT.}This is because SNAPSHOT made asnapshot of the computer memory(process image) and the cpu image,and has now brought it in}to theforeground.Load in another program into thesecond system. From now on all youhave to do to switch between thetwo }virtual systems is press andhold Shift-Control-1.Note: SNAPSHOT may hang up if youuse Sparta's BASIC ON or BASIC OFFcomm}ands. This should be no problemsince all you have to do is hitreset to get control back again.SNAPSHOT should still be the}re, andso should the second process.___________________________________ FIXES AND ENHANCEMENTS ----------}------------Ver. 0.5 / 1-3-90I fixed SNAPSHOT to work with AtariDOS 2.5. I haven't had the chanceto test it out on ot}her DOS' yet.Also, I've incluced "SOFTBOOT.COM"in the beta tester's package."SOFTBOOT.COM" allows you to havetwo differe}nt DOS' in the computerat once! Directions for it's useare as follows:1- Boot Atari DOS 2.5 without BASIC and without }RAMDISK.COM, or the MEM.SAV file on the disk.2- Load SNAPSHOT.COM from the DOS menu using option L.3- Initialize th}e second SNAPSHOT with a Shift-Control-1.4- Load SOFTBOOT.COM from the DOS menu using option L.5- Then Softboot ask}s you to put the new DOS disk you want booted from into the drive and hit RETURN. What could be simpler? I'm work}ing on making it more flexible.Also, I added a second EASIER wayto switch between snapshots inaddition to the Shift-Co}ntrol-1 keycombo. You may also use the [HELP]consol key to do this!Ver.1.0This latest version is now fullycompatable} with MyDos 4.5, AtariDos 2.5, and Sparta Dos 3.2. Byusing SOFTBOOT.COM you will be ableto have one of the Infocom gamesr}unning in one snapshot. I'vetested Cutthroads and Hitchhiker'sGuide to the Galaxy with noproblems. SNAPSHOT is "somewhat"}compatable with Atari BASIC(experimentation is required here),but not Turbo Basic. It also worksfine with TextPro.With t}he release of version 1.0,I'm placing it into the hands ofthe general public. There's stillwork that needs to be done toS}NAPSHOT, but I feel that it issomething that the general Ataricomputing public will find useful.Special thanks to my beta }testers(you know who you are). Keepdropping in on the bbs and givingme your suggestions._______________________________}____ THE FUTURE ----------Watch for future developments andenhancements to SNAPSHOT. I'll bewor}king to make SNAPSHOT compatiblewith as much software as possible. Tom Hunt } 01/01/90___________________________________ SHAREWARE ---------If you use and enjoy SN}APSHOT, andare feeling generous, why not dropa buck in an envelope and mail itto: Tom Hunt 1704 Tw}p.Rd.65 Jeromesville, OH USA 44840A dollar isn't much. But since thisis shareware, what the heck? An}d ifyou are feeling even more generous,please jot down on a note tellingme what software you are usingSNAPSHOT with, and }how it benefitsyou.___________________________________ FINALLY -------FOR THOSE WHO ARE M}ORE EXPERIENCEDIN PROGRAMMING, If you find thatneither the Shift-Control-1 or theHELP key works right with a certainappli}cation, here is a suggestionon what you can do. We are going topatch SNAPSHOT.DO NOT ATTEMPT THIS PROCEDURE ONYOUR ONLY }COPY OF SNAPSHOT. Yourisk damage to not only theprogram, but you could also damagethe integrity of the disk itself!Anywa}y, load up your file/sectoreditor, and look for this in thedisassembly- CMP #223That's the hardware value }ofShift-Control-1. Change it to anyvalue that you feel would work goodwith your application.____________________________}_______-Control-1. Change it to anyvalue that you feel would work goodwith your application.____________________________0 B/DEHI V`   }  (C) 1990 by Tom Hunt    |  Find suppo}rt  |  |   |  |   |  |  |  |} call the |  |^^^^^^^^^^^^^^^^^^^^^^^^^^|     | |}  | Ӡ |  | |  | |  | }󭭷 | Home | | Home of  of  MTOS, The Works, The WorksXE }  Snapshot ح   ޅ  L}Ө)xLcөXhhh@$%)Ӡ L` `L-} Snapshot V1.0 installed B D}E!HI V$%b$%`xԭӍ)ӭƓǓ$%ȓɓhhhhhh H HHHHH  }ޅ   @Ȁˀˀɀ  ӽ@)ӽ@Øf@ ӭÝ@ ɀо @}*--ɀccDGXԮȓLc^Щé ҭLةíÍ ú}ÚúÚØ鍩@© Ӣ@Ø@Ý­@֩@!Í-Í4ÍBé ӭ ӽ}@)ӽ@Ø@ ӭÝ@!-4BíBɀоuÍ_Гé@yÍé ӽ@Ø@Ýuyí}֩Íýêý L ` _Гé@yÍé ӽ@Ø@Ýuyí=R@   Y`R@   Y`΀0!@i   Y`}L} FMS INITIALIZER (C) 1990 Tom Hunt BzDEDHI VL BߝDE}HI VL8Have two file maintenance systems in memory at once!
