I specifically want to know how the class library and language evolved after the licensing (which is about when the Xerox features of Squeak were frozen) and before the language went commercial. The Purple Book and _Inside Smalltalk_ mention some features that aren't in Squeak (the simulation classes, multiple inheritance, and temporary variables inside blocks) but I was looking for a more detailed list with dates. My ultimate goal would be to put those features back into Squeak. Have you ever used any of the Xerox workstations? That's something I always wanted to try. -- Derek

...and here's another - HP9000 question

by agraham＠ccat.co.uk

Hi folks, I forgot to mention, in the crash I had last week that damaged the Apple /// etc I also had an HP Apollo 9000/600 workstation with 19" monitor. Whilst I'm assuming the front passenger airbag caught the monitor since it was unrestrained on the front seat (but the seat was pushed right up to the dash) it is now however refusing to display blue. If I remove the B plug on the RGB cable the display doesn't alter......since if I remove the green the sync goes and they're from a similar era could I substitute a spare DEC VRT21 I've got lying around here in the office? That monitor is a 60hz 1280x1024 RGB sync-on-green Trinitron. Of course, I'd like to repair the HP's monitor, but my knowledge of repairing monitors begins at the glass fuse and ends on the high voltage bit :) Oh, and anyone know why the PSU fuse in the Apple ][c is soldered in rather than being in a carrier? I blew my ][c when I forgot it was a US one.....doh.....I can solder in a replacement fuse but I just thought I'd ask if there was a reason why it was soldered....if I can get a carrier to fit I'd rather do that! cheers -- Adrian Graham MCSE/ASE/MCP C CAT Limited Gubbins: http://www.ccat.co.uk (work) <http://www.snakebiteandblack.co.uk> (home) <http://www.binarydinosaurs.co.uk> (80's computer collection) "Missing you already" - Mark Radcliffe

Micom

by lgwalker＠look.ca

I've been a lurker and sometimes participant in classiccom for some time but other than a couple of instances (one-my own query and the other from Charley Fox, who has/had a 2001 (IIRC) ,there has been no mention of a machine contemporary with the Altair and that precedes the Apple One. While it was peddled as a word processor it was indeed an 8080 box. It has a passive backplane with 30 pin sockets and looks similiar to a PET (including the fold- up monitor to expose the inner-workings) with a separate keyboard connected by ribbon cable and in my case a Shugart m.802 8'' FDD. Unfortunately I don't have a com program for it (they were available- one was called Miconet) but I keep hoping things will pop up. It also had a language program for it-"Micom 80"- a modified MS Basic80 . I picked it up in the late 80's It came with a Qume Daisy-wheel printer whose separate power- supply weighs about 50 lbs. itself (I even have a garbage-found spare). :^) Below are time-line references for some perspective : >FROM TIMELINE OF MICROCOMPUTER HISTORY................Poulsson March (75) Fred Moore and Gordon French hold the first meeting of a new microcomputer hobbyist's club in French's garage, in Menlo Park, California. 32 people meet, including Bob Albrect, Steve Dompier, Lee Felsenstein, Bob Marsh, Tom Pittman, Marty Spergel, Alan Baum, and Steven Wozniak.

His previous company, which was sold to Phillips NV of Holland, had 1100 employees. http://www.lisco.com/terra_globe/vdsdescrip.html The 2 companies they mention are Micom and AES (an early Canadian electronics company who also made computers) It makes me wonder whether he might have had anything to do with the Hyperion start-up since he was so integral to the Canadian electronic industry. One of their brochures(June,1981) brags about the 50 Micoms used by NASA which were their primary word/data processors, and were linked to the NASA's central mainframe. Has anyone any info on this machine ? I have a copied software manual and some brochures and Phillips Micom newsletters. ciao larry lgwalker(a)look.ca walkers(a)altavista.net bigwalk(a)xoommail.com

While we're talking about Lisas

by agraham＠ccat.co.uk

My Lisa 2 (vanilla one, 1.2A PSU) has developed a habit of turning the screen off while she's running. In fact it's now permanently off which is annoying to say the least. Some of you may have experienced this before so here are the symptoms; System working fine (at the time running MacWorks 1.0), screen goes dim as per screensaver then blinks off like I'd hit the power button. It eventually comes back on after leaving it powered down for a couple of hours. James at Sigma Seven Systems said he thought he remembered there was a serial port bug in MW1.0 that caused the screen to go off sometimes so I left it at that. I've now got myself a ProFile so I was intending on installing LisaOS 3.1, but when she was powered up for the first time since maybe mid-may the screen came on briefly then blinked off again as it did before; since then it's only come back on once for around 10 minutes. While all this is going on the machine keeps running normally. If I power up I hear the self test passing, if I've got the first OS disk in (or MacWorks boot disk) it will actually boot, if I've got a standard composite monitor connected I can see things happening so I know the machine itself is fine....... Anyone else seen this? I've got another video card and screen coming over but it won't be here till the end of august; to say I'm champing at the bit would be an understatement :) cheers!

That would, at least, place the visit into late 86/early 87, years after the *two* vists of Apple personnel to PARC, and at the end of the Star's lifecycle as a product. The definitive story of the development of the Lisa GUI can be read at: http://home.san.rr.com/deans/lisagui.html As the final design jelled, the designers did make comparisons between what they'd come up with and the Star interface. IIRC, property sheets were one of the big Star features that had a direct analogue in the Lisa GUI. BTW, the Green Book remains the best source for info on the various implementations of Smalltalk (I have 3 of the four books original projected for publication, Blue, Orange, and Green; the book on Creating a User Interface that would have documented using MVC (Model - View - Controller paradigm) was never finished. Later, the Blue Book was discontinued and replaced with a Purple Book which omitted details on how to implement the Smalltalk Virtual Machine. regards, -doug quebbeman

> I've been trying to find anyone who might have the early Xerox release > images that were provided to their licensees, Apple, HP, Tektronix, etc., > as described in _Smalltalk-80: Bits of History, Words of Advice_. Ok. I have two versions of Apple's Virtual Image 1 release; these are the second and third ones Apple did. I'll have to check Kurt Scmucker's book tonight; the first release I knew of was the Macintosh XL version (not quite a Lisa anymore). IIRC, the second release was to support the Mac 512k (where I enter the picture, having owned the Blue Book for a year and not believing I could acquire ST80 for US$50.00!!!). The second release was to support the Mac Plus' 1MB of RAM. There was a third internal release which replaced the MVC-based GUI with the standard Mac GUI, all done with a Smalltalk version of MacApp. Xerox then takes all the feedback from the Virtual Image 1 testers and creates Virtual Image 2. There are updates, I think VI2.2 is actually what gets shipped. Two versions are marketed for the Mac, 'DE' which is for the Mac and Mac Plus, and another, can't recall the designation, which is marketed for the Mac II (68020 code). I have Smalltalk-80 VI2.2 DE, in vanilla and heavily enhanced form. I do not have any docs that accompanied the product. This period lasts about two years, then the product line off as ParcPlace Systems. The first product they ship is Virtual Image 2.5, which has Peter Deutsch's J-I-T compiler and virtual machine. Very fast. Things get boring after VI2.5, as PPS quits chasing technology and starts chasing dollars. > I've asked several people who worked on it at PARC, and the responses > I get are mostly "use Squeak instead".

AFAIK, APple never produces a VI2-based system. Kent Beck or Larry Teslar could perhaps answer that more accurately. Another person to ask might be Sam Adams, at UIUC (he used to have a Smalltalk firm in Triangle Park). > I'd also like to get the Lisa version. It either ran on the bare > metal or on Monitor, I'm not sure which. The original disks for the two Apple releases I had are acting as growth medium for something green, having spent time under water. :-( I may have archived the disk images before that happened; I most definitely did manage to archive the ST80 VI2.2 DE disks. Eric, if you're up late mailing, send any queries to me at dougq(a)iglou.com Take note of the confusing 'G's and 'Q's in that address. regards, -doug q

It is a "SPRITE 1" by Synetix Systems, Inc., 1983, with a TMS9918A, eight memory chips (8328GVP AM9016FPC), four 74LS chips, one other chip, video input and output RCA jacks, and the usual assortment of descrete components. I also have a manual called "apple-seed II" which has parts lists, component layouts, and instructions for assembling Apple II compatible cards. Page 3-3 lists a Sprite Graphics Card which also uses a TMS9918A chip but has a different layout and only one chip (74LS00) besides the 9918 and memory (TMS4116) chips.

RamKeeper fires?

Asking for info on the cards in my new IIgs, I'm getting stories that the Applied Engineering RAMKeeper was reportedly the cause of a couple of houses burning down. Anyone have anything on this or is it just another UL?

I have it on good authority that Smalltalk-80 was not ported to the Star. It was running on the Alto and the Dolphin at the time, as well as another Xerox workstation whose name I can't recall. Larry Teslar was working at PARC at the time, and ended up following Jobs back to Apple, because Xerox couldn't get their asses in gear and Apple looked like it knew what it was doing (w/r/t getting new technology out the door). For those interested in what Smalltalk-80 feels like to play with, you should try Squeak, a successor developed by some of Smalltalk-80's authors, Alan Kay and Dan Ingalls, at Disney. Squeak is everything ST80 was and more. You can find info about Squeak at: http://www.create.ucsb.edu/squeak/ > 2 of the main developers of the Mac platform were Bruce Horn > and Jef Raskin, their side of things can be found here: Bruce Horn also "did time" at PARC, working on Smalltalk-80. -doug q > http://www.apple-history.com/quickgallery.html?where=lisa.html > > Follow the link at the bottom of the screen.

RCS/RI Open House

by aw288＠osfn.org

I suppose I ought to start advertising on the list. Anyway, the Retrocomputing Society of Rhode Island will be holding this month's open house on the 15th of the month, next Saturday, at our Millspace in Providence, Rhode Island. Directions can be found on our websight at <www.osfn.org/rcs>. This month's topic is the machines of MAI/Basic Four. Essentially, we will be examining just what we have in this line, as we have really done little with the machines since we obtained them. We will also be discussing a possible move to another room in the building, our recently arrived Symbolics machines, the electrical upgrade, future open house topics, and so on. There will also be a great deal of general computer geek talk. Please email me (or the list) with any questions. All are invited. No charge! William Donzelli aw288(a)osfn.org

I kept some pieces, most notably the 8-inch Tandon floppies and the daisywheel printer. Gave one Tandon away. It was 8080a based, IIRC. Have never tried the printer, strangely enough. Could be what I had was somrthing else, tho... -dq

SY/LINK Network Interface, Square-D PLC Network I/F card, ISA

by whdawson＠mlynk.com

I found this type SFI-534 card in an IBM 5155 I recently bought. No software for it was on the 5155's hard drive (21mb Seagate). What is intriguing is what is on this board: MC6809P (socketed) MC6850P MC6840P MC6854P HY6264P-10 (x2) HD46504P/HD6844P AM2130-12PC (socketed) 27264-25 EPROM (socketed) DB9M and DB9F The board is switch selectable to be addressed anywhere from CA000-CA3FF through D3000-D33FF. It looks like it can be a lot of fun to play with if I can find any information (I.E. Schematics, etc.). From what I've found out so far, this board uses RS-422 for communication. All the receivers/drivers and protection circuitry is under the metal cover. Anyone know anything about this board? There's one very similar to it on eBay now: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=381126929 ,with photo. I put a $0.01 bid on it just so I can easily track the action, so if anyone else wants one of these boards, feel free to bid on it also. I have no desire, yet, to own another one.

Apple IIgs Find!

by dlw＠trailingedge.com

I just received an Apple IIgs with some cool cards and I'm looking to see if anyone has doc or software for these. The machine is a: Apple IIgs Rom 3 (But with a Woz signed case) Apple IIgs Memory Expansion (1 meg) Transwarp GS Apple II Video Overlay Card (This was the main card I wanted!!) Applied Engineering RamKeeper Battery which seems to go to a small card attached between the PSU and slot 1. I think this keeps power to the Ram. 2 3.5" drives 2 5.25" drives Keyboard & mouse ImageWriter II Printer But no doc or software for any of it. I'm interested in anything people can tell/send me on the Video Overlay Card mainly but also the Transwarp GS and the RamKeeper. Thanks in advance. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Intel MCS-80 Cross Development Software Available

by dhquebbeman＠theestopinalgroup.com

Ok, I have placed the Intel 8080 Macro [Cross] Assembler, the Interp-80 Simulator, and the PLM-80 Compiler in my web storage area. I've placed a tiny page at: http://members.iglou.com/dougq/8080/xmcs80.html >from which you can download the source files. As these filename extensions imply, these programs are Fortran-IV (some call it Fortran 66) source code. The files are in ASCII with CR & LF line termination. The MAC80 source still includes its program sequence numbers in columns 72-80; the other files no longer have the sequence numbers; I'm not sure how that came to be, whether I never had copies with sequence numbers, or if I stripped them to make them wasier to work with on slow serial connections. They may display incorrectly in your browser unless you add a MIME filetype for .FTN files that's otherwise identical to .TXT files. For IE user, just right-click on each link on the page and select "Save target as..." and save to your favorite location. After examining them, these do not appear to have the extensions I recall adding (although there are some non-standard changes to MAC80), so they may well not have the bugfixes either. The copies I worked most closely with were the CDC6600 and DEC-10 ports. I should have those, but they're trapped on CDC 9-track tapes, and I haven't yet remembered how to use Prime's MAGNET program to read them successfully. Feel free to download the code. It's copyrighted by Intel, but I intend on asking Teresa Knezek to add them to the Abandonware list, and to contact Intel for permission to make them freely available under hobbyist license. Grab now, if I get a cease- and-desist letter, I'll have to pull them off immediately. regards, -doug quebbeman

Apple II keep list

I've just got a load of boards etc from the bloke who runs the Apple Retrospective website; I know there's CoPro boards/serial boards/80 column cards/drive boards etc but haven't inventoried it all yet. That's a handy list to have....

Imagine my horror when I was hit by another car bringing it all home! It all survived though, except the keyboard on one of the ///s, but it's repairable I hope.

>From what I've been reading in the last couple of months it was neither - both Steve Jobs and Gates toured Xerox PARC in the late 70s; Lisa at this point was already in development but needed a front end so the Lisa team took some of the ideas from Smalltalk running on the Xerox STAR and improved on them to develop the QuickDraw primitives found in Lisa. Gates apparently got more ideas from when Microsoft were at Apple while Apple were helping them develop software for the Mac that was being worked on at the same time. 2 of the main developers of the Mac platform were Bruce Horn and Jef Raskin, their side of things can be found here: http://www.apple-history.com/quickgallery.html?where=lisa.html Follow the link at the bottom of the screen.

Helios Source (Was: RE: Jim Battle's SolACE: The next steps)

by dhquebbeman＠theestopinalgroup.com

In all this talk of Sols, I recall that Stan Sokolow had finally managed to wrestle the source code to the Helios disk OS away from whomever it was who ended up with the PTC IP rights. Altough it was proprietary in lots of ways (hard sectored 8" drives, IIRC), it was a decent design. Anyone got it?

Jim Battle's SolACE: The next steps

> If you go to > > http://www.thebattles.net/sol20/soldocu.html > > you'll find chapters 7, 8, and 9 are already OCR'd and PDF'd. Well, I missed that when I first checked out your site. How cool, you've got the Access newsletter I used to have (don't know what happened to them), the BASIC/5 manual (ditto). What I see you don't have is the Trek-80 manual; you have a space for the Popular Electronics article; do you need me to scan that for you (I do have it)? I also have the smaller document package that came with what I initially bought, the Sol-PCB, for <drumroll please> $40. However, its location on the basement floor was a bad place to be during a flood, and the individual pages are glued together by mold or lordknows. Some carefull soaking may allow me to separate them. I'll try to inventory everything tonight, and compare it to what you've listed. Great work, Jim! -dq

CBM Plus/4 malfunctioning...can anyone help?

by retro＠retrobits.com

Greetings, I've got a Commodore Plus/4 that's not working quite right. When I turn it on, it does power up, but doesn't boot to BASIC. Instead, it "breaks" into the machine language monitor. The following is displayed: BREAK PC SR AC XR YR SP ;8008 B5 08 00 00 FF Looks like one of the chips is fried, but which? My initial guess is either the Kernal ROM or BASIC interpreter is shot. Any guesses? And does anyone know where I can find some Plus/4 spare parts? :-) Thanks and best regards, Earl Evans retro(a)retrobits.com

Running GS/OS On an Apple IIgs

Thanks for the info! I was just about ready to throw my GS out the window. How much do you want for your GS, and what kind of stuff comes with it? Do I really need 2 megs of RAM to run GSOS?

Coming Soon: Intel Mac-80, Interp-80, PLM-80

by dhquebbeman＠theestopinalgroup.com

Some of you may have seen my recent post about being able to restore data from very old 9-track magtape. Although I seem to have lost some 8080 assembly code I wrote (and some I didn't write but did laboriously type in), I was successful in getting the old Intel cross-development software back. The three programs are the Mac-80 Cross [Macro] Assembler, the Interp-80 software simulation of the MCS-80 8080 CPU, and the PLM-80 compiler (a two-pass monster). Now, the PLM80 compiler Fortran source has been available on the Digital Research archive and its mirrors for some time now. But I spent quite a bit of time with these three programs, fixing bugs and providing some minimal extensions. I am assuming I migrated the fixes and extensions to the Prime ports of this code. If so, then what I've got should be preferred over other copies (I'd ported these to the DEC-10 and the CDC6600 as well). So, as soon as I have a way to get stuff off the Prime and onto a PC, I'll upload them to my web storage area, and provide links so anyone interested can download them. I hope I didn't waste my time doing this; I searched high and low on the web for Mac80 and Interp80, to no avail. regards, -doug quebbeman

Either this weekend, or one two weeks hence, I'll see if I can find my tapes and dust off the SOL and get copies made of each and get them to you. Bob, did you add the zero-crossing fix to your casette interface? Do you have the SOL manual scanned and converted to PDF? I'll be making five photocopies of the one I'll be selling on E-Bay in a few days, and I can scan any pages I might have that you might not have, and forward them to you.

Jim Battle's SolACE: The next steps

by r.stek＠snet.net

I am glad that Jim has released his Sol emulator (if you didn't see his message look at http://www.thebattles.net/sol20/solace.html) He has done a fantastic job - Sol owners and Sol-wanna-be owners owe him a tremendous debt of gratitude for making the Sol live again. His web site already has a very good collection of both usable software and documentation (much of generously shared by many list members). I propose to make it even better. I have begun OCR'ing and pdf'ing the paper documentation I have. And I have just compiled a tape to send Jim (including such goodies as Microsoft BASIC for the Sol, MSA BASIC, 8080 Checkers, Computer Mart of NJ Dynamic Debugging System, Electric Pencil, and others). (okay, okay, so there may be some copyright issues here! But putting those aside....) I can OCR and PDF documentation. I can repair (some) cassette tapes (the pressure pad often comes unglued, but Radio Shack has repair kits) and make backup copies on new cassettes. But I can't do what Jim can do. Jim has already designed and hosted the website I only dreamed of. I would prefer that he spent his time on improving and extending SolACE. So here's the deal ... With Jim's approval I am willing to act as a clearinghouse for any and all donations of programs and documentation to be made available on Jim's website. I would prefer originals (with the understanding that I will VERY carefully copy and return them) or good, clean copies of any ProcTech Sol programs and documentation which are not already available on his site. I will catalog, research, annotate, OCR, PDF, convert, etc. whatever I can and transfer same to Jim for inclusion on his site. I will try to track down copyright holders and even make this stuff legit (if necessary). Obviously I am an extreme example of a Sol nut. But I do think that the Sol played a pivotal role in the evolution of personal computers, and it deserves a chance to shine again nearly 25 years later. This is an example of a little project that the classiccmp list is in a unique position to help along. So how about it? Go out to that storage shed, dig deep in that cellar, see what you can find. Check out Jim's website, and if he doesn't have what you have, then drop me a line. I'll let you know if it is something I am already working on or not. Note to Sellam: might make a nice freebie for the VCF - I bet Jim could provide SolACE and program or two, and I'd be willing to do a little write-up about ProcTech and Sol. I can see the advertising now: Attend the VCF and receive your very own 8080 Sol computer!

Running GS/OS On an Apple IIgs

Uh.... a thing which is illegal in one state but legal in another cannot, by definition, be a federal crime. There are grey areas, like the Mann Act, which deal with transporting minors across state lines, but each state can define "minor" differently. Did you mean "felony"? Or were you referring to how the establishment acts about it when you commit it? That, I *do* understand... -dq

PDP 8/I

by djg＠drs-esg.com

I assume you have seen the stuff on highgate and my website. I am working on a search for the documents, Highgate doesn't have all the scanned documents online, the search will have them all. I will also have the search have the option of converting to PDF. I will post to the list when it works. I also have more 8/I stuff not yet scanned if you need something in particular. I have put a no longer accurate list of manuals I have at http://www.pdp8.net/document.txt I also have spare boards if you find you need them. I normally try to trade for something (extra hardware/docs or copies). A lot of paper tape images are available on the net. With the right adapters you can hook it up to a PC to download. I have done this with my 8/I. See http://pdp-8.org/papertape/. You should also be able to punch physical copies with your punch and a little software. If you have TC01 with a TU55 or TU56 I have 4K disk monitor system which says it works off of a DECtape also. I only ran it from DF32's. The manual is already scanned, I will get the tape on my site and send to pdp-8.org. Email me if you can't find it when you need it.

I rescued it from a public school locally (I already had an -8/L, so I knew what I was looking at). Mine came with 4K, a DF-32 master and two slave disks. I have no expectations that the media are any good at this point, but the last time I fired it up, the controller was working enough that I could read the status register and watch the rotation sensor on the console via a tiny toggle-in program I wrote to check it (I had to rebuild the rotation sensor on one drive because it caught fire in the housing!) There are some docs on Highgate and you might be able to find the DEC 1970 Small Computer Handbook for the basics. If you care to try out any papertape or DECtape programming systems, you'll want the Programming Handbooks. There's good info in those on how to load and start FOCAL, etc. Have fun with it; I wish I had reasonable peripherals on mine. The best I can do is move my PC8 to it and load paper tapes faster. I have a TD8E and a TU56, but nothing for an older machine.

There are some similarities in the design, suggesting >that the Boca Raton folks were at least partially inspired by it. Exactly, Anyone with 8085 experience could easily loft the design to an 8088. Intel even had an ap-note to put an 8088 in an SDK-85 board (I did it too) and it was pretty easy with the big difference being the monitor rom. Keep in mind the design window was in 1980 and by then the 8080 was a non contender as the 8085 and Z80 had replaced it. If you look at the late '79 and early 1980 mags (Byte, KB, IA etal) you would see there was an emerging push for more cpu, more bits to do math and more bits for addressing. If they used an 8085 (or z80) they were an also ran to tandy, Apple softcard, NS and a raft or other already known 8bit systems. The only place there was room to make a point was the 16bit front and the 8088 was a well known (it had been around for about two years) relatively cheap way to get there. Allison

VCF Link Library Improved!

by vcf＠siconic.com

In my continuing quest to make the VCF Link Library ever more useful, I've split up sections into sub-sections where applicable. For instance, the DEC section is now split into PDP-8, PDP-11, VAX, etc. The Apple section is split into Apple ][, Macintosh, Lisa, etc. You get the idea. Also, specialty sites for each section have been split out, such as Software (for sites that have software resources for computers in that section), Documentation, Emulators, etc. Check it out at: http://www.vintage.org/cgi-bin/links.pl There are currently over 700 links total in the database! If your site is not listed, add it now! http://www.vintage.org/addlink.html Sellam International Man of Intrigue and Danger ------------------------------------------------------------------------------- Looking for a six in a pile of nines...

Z80 Starter kit plus ...

by ncherry＠home.net

I have a Z80 starter kit which I've torn apart and reassembled. This one is rather nice in that it came with a power supply, connectors and a wire wrapped section already added. It was probably used at a local community college (Mercer?). The wire wrap job is very pretty (hey it's art work :-). I also picked up an Applied Microsystems Corp. EM-180B (Z80 diagnostics emulator). Soes anyone have any docs on any of this? I've had experience with the emulator (I worked with the 6802 and 6809 emulators). So I've been able to use it, I just want to know what the rest of the bells and whistles do.

Tektronix terminal available

by mike＠delos.rain.com

I looked but didn't see a model number in any obvious place. I bought it a long time ago because I was fascinated by the Tektronix displays used in the "Battlestar Galactica" TV show. Unfortunately I never got my hands on the documentation for the graphics display commands. I would have loved to get copies of the programs they used for the show (even now that might persuade me to keep this terminal). The terminal itself isn't very large, but it does have an integrated floor stand and is rather heavy (shipping might not be very practical). I live in the Portland Oregon area; if you're within reasonable driving distance. I wasn't planning to ask for money, but I do have a wish list that includes a Kaypro, Osborne, Zorba, or some other interesting portable CP/M computer. If you're interested, feel free to contact me (even if you don't have anything to trade). I'm trying to free up some space to make my wife happy... ----------------------------------------------------- Mike Newman INTERNET: mike(a)delos.rain.com Aloha, Oregon USA -or- mike.w.newman(a)gte.net http://home1.gte.net/res003ki/index.htm ----------------------------------------------------- High-resolution - If you stand more than four meters away, you can't see the dots.

OT: Tektronix 531 oscilloscope available

by mike＠delos.rain.com

Includes "Scope-Mobile" cart, some plug-in modules, and even a few spare parts. It worked when I got it but developed what I believed was a high voltage power supply problem that I never got around to repairing. Now I need the room more than the 'scope, so I'd like to find someone who can use it. Shipping is probably not too practical because of the size and weight, but if you live within reasonable driving distance of the Portland Oregon area and are able to come and get it, contact me for directions... ----------------------------------------------------- Mike Newman INTERNET: mike(a)delos.rain.com Aloha, Oregon USA -or- mike.w.newman(a)gte.net http://home1.gte.net/res003ki/index.htm ----------------------------------------------------- Velleity (vuh-LEE-ity), n.

Solace: Sol Anachronistic Computer Emulation

by frustum＠pacbell.net

Like the subject line says -- I've written an emulator for the Sol computer. It is a Win32 application and should run fine on any pentium-class machine. It currently doesn't support any disk drives, the cassette port, the serial or parallel ports. Still, you can do a surprising number of things, especially since you can "download" programs via a menu (much faster than the cassette interface!) Yes, you can run TARG, although I haven't yet tried placing an AM radio next to my computer to listen for the sound effects. :-) Solace is a work in progress, but it has already seen a fair amount of beta testing, including some by the list's own Bob Stek (Saver of Lost Sols). The emulator is quite simple to run, and it doesn't require any nasty installation procedures, modifications of the registry, etc. Just unzip it and run. If you are interested, go check it out (including a screen shot) here: http://www.thebattles.net/sol20/solace.html If you get tired of the programs that come with the ZIP file, download some more from the Sol archive: http://www.thebattles.net/sol20/solpgms.html And as long as I'm here, if you have any Sol docs or programs that you could share with the Sol archive, let me know about it. Thanks. ----- Jim Battle == frustum(a)pacbell.net

Need Freon TF Substitute for Head Cleaning

by xds_sigma7＠hotmail.com

Interestingly enough, my "IBM Tape Unit Cleaner" (the real offical stuff!) says it contains Trichlorotrifluoroethane AND isopropyl alcohol. This is stuff that I use on an 8809 drive, which is a top-loading, lift-the-cover sort of a drive, much like a CDC (nee DEC) TU80... if it works for IBM, I wouldn't be too concerned.

HP part number cross reference?

by eric＠brouhaha.com

Does anyone know of an online HP part number cross reference? I'm almost postive that I've seen one somewhere, but I can't find it now. I need to find the industry equivalents of the parts listed below. The 1810 prefix parts are probably just resistor packs (although the 16-pin ones could be RC networks or the like), the 1820 prefix parts are probably all 4000-series CMOS, and I'm guessing that the 1858 prefix part is an analog circuit. The T-28751 has a Motorola logo, but no other part number, not even an HP 4x4. I've occasionally seen other T-prefix parts in HP gear, but they seem fairly rare, and I'm not sure what the T signifies. I've tried HP PartSurfer, but it only listed one of the parts and didn't give any detail other than "MOS": http://outfield.external.hp.com/spi/ Thanks!

origin of gates quote on 640k memory...

by allisonp＠world.std.com

From: Neil Morrison <morrison(a)t-iii.com> >FWIW, I believe his opinion was that 128K was enough. My recollection is >that he wanted that amount to run Multiplan, and that is why he talked >IBM into using the 8088 instead of the intended 8080 for the IBM PC. >I believe this because Radio Shack sold add on cards for various Z80 >boxes they made so as to provide 128K for Multiplan (mainly). Thats so far out left field that I can say there is little basis for it. RS was not a significant vendor for memory cards or extensions. As to the choice of 8088 vs 8080, nobrainer. Everyone knew by 1980 that while the z80 was a great cpu there were an emerging class of apps that really needed 16 (or more) bit wide ALUs and memory to perform well. Graphics was one of the emerging apps and the other was programs like multiplan (math intensive). These and others were the push for the 16bit world. Additionally 8080 was quite passe` by 1980, 8085 maybe as it was available as a 5mhz part (vs 8080 at 3!) and Z80 at 4mhz. There was also Z8000 and other promised parts for the 16bit world to come. I suspect 8088 won as it was quite easy to interface and use. Another point, Multiplan ran under CP/M with 48-60k of available memory and most 8080 class (include z80) didn't have a MMU to manage more nor did the OS (CPM2) have management. I have several systems that still run multiplan (8080 and z80), they used overlays and on disk storage very intensly to get around memory shortfalls. Additionally PC even early on were rift with code bloat (8080 lofted code tended to expand) and it was deemed a requirement to have more than 64k mostly due to the OS eating most of it. At the time 256k was enough and it was felt (just like a few years before when z80 64k was plenty) that was enough and if not 640k would insure enough space. This is true also due to the segmented addressing the 8088 used, it was still largely a 8/16bit cpu with 16bit basic addressing. Apps didn't grow well until the 286 memory style and more aptly the 32bit 386 appeared. An aside, non PC 8088/86 systems used to permit a full 1 MB of ram via rom shadowing or added a mmu to extend beyond 1mb. So Billy boy was really refering to those system that were promoting the full 1mb or larger memory maps. Allison

Are they different names > for the same stuff, or two different stuffs? Just the positions of the various halogen atoms relative to each other. The 1,1,2 form specifies a particular arrangement, the other is non-specific. Schematically, this is 1,1,2-trichloro-1,2,2,trifluoroethane: Cl F | | F--C---C--Cl | | Cl F In other words each carbon atom has one halogen of one type and two of the other. There's one other possible arrangement[1]; where all the chlorine is on one carbon, and all the fluorine is on another, which would be 1,1,1-trichloro-2,2,2-trifluoroethane. I've no idea if that makes any significant difference to any of the properties you and I would be interested in, but I suspect not, and that most trichlorotrifluoroethane is a mixture of the two. [1] From my 2-D ASCII art, you might think there are other arrangements, eg swapping the position of the fluorine for one of the chlorines on the first carbon atom. However, if you think 3-D, and imagine the carbon as one apex of a triangular pyramid (meeting the second carbon at the apex of another pyramid) and also realise that the carbons can rotate relative to each other, you'll see that all the other permutations are equivalent. BTW, this is iso-propyl alcohol: H / H O H | | | H--C---C---C--H | | | H H H You could also call it 2-hydroxy-propane, or propan-2-ol. The O-H group is what makes it water miscible (in fact, it's mildly hygroscopic), and of course it's also highly flammable, unlike the chloroflurocarbons. To get ordinary ethyl alcohol, chop off one of the carbons and two corresponding hydrogens. -- Pete Peter Turnbull Dept. of Computer Science University of York

Cubix System... Anyone know the pinout of the Video/Keyboard/ Mous e Connector?

by RCini＠congressfinancial.com

Al: I had this issue on a Cubix 486-based SBC that I'm using for a firewall. I wound-up ordering the breakout cable from Cubix for $35. It is a small PCB on an ISA bracket and it has a video connector, mouse, and keyboard connector. It appears that there are coils or something on the board, probably for noise rejection and the like. Cubix was fairly helpful, giving me the part number to use when I called the parts line to order it.

An article in Byte magazine years ago on the development of the IBM PC said that IBM took an unsanctioned R&D project being worked on by a couple of guys in Boca Raton and it, with all its shortcomings, became the IBM PC. But the engineers deliberately chose the 8088 for its ease of interfacing (8-bit) over the 8086, which required more support logic. I suppose it was possible that IBM chose the Boca Raton project over some other (unknown to me) 8080-based project due to the requirement you mention. But I don't think they retargeted their design from 8080 => 8088. regards, -doug q

Need U.S. source for belt for Amstrad PCW8256 3" drive

by whdawson＠mlynk.com

Hello all, Here's the dimensions of the needed belt: 72mm x 3mm x 0.5mm also acceptable: 71.0mm x 2.8mm x 0.6mm or 69-72mm x 3-4mm x 0.5-0.6mm The rest of the story: I picked up an Amstrad PCW8256 today complete with printer, original disks (LocaScript and CP/M Plus), 2 game disks with instructions, 5 spare disks with LocaScript files from the previous owner, the Start Up Guide and the User Guide. All for $10.00. It is in great condition and appears to have had little use. However, this is the first Amstrad I've ever owned (or seen for that matter), and also my first experience with these strange 3" floppy disks and drive. I was told it worked, but upon getting it home I found it wouldn't boot. After some poking around I decided to take the floppy drive out and check for head movement. This is when I discovered that the floppy only spun when I pulled up on the pressure pad. At this time it started seeking, so seeing that the spindle is belt driven, I knew where the problem was. I removed enough screws and connectors to get to the old belt out and replaced it with an appropriately sized rubber band. After reassembly, everything now works great. It boots LocaScript, CP/M, and runs the games. But..... I'd like to replace the rubber band with real belt. Can anyone help? Bill Dawson whdawson(a)mlynk.com <mailto:whdawson@mlynk.com> ?

Stupid chemistry question from someone who took too many physics classes and not enough chemistry: What's the difference between trichlorotrifluoroethane and 1,1,2-trichloro-1,2,2,trifluoroethane? Are they different names for the same stuff, or two different stuffs? I have some of the 1,1,2-trichloro-1,2,2,trifluoroethane stuff (in the form of Kodak film cleaner) and it has (from experience) different chemical properties than alcohol. Isopropyl alcohol seems to loosen up laquer-based paints; the 1,1,2-trichloro-1,2,2,trifluoroethane doesn't seem to touch paint at all. So the difference may be important if you're cleaning an assembly held together with a laquer-based adhesive. Tim.

Reading Old 9-Track Tapes (RE: Pertec Interface Cable Fun)

by dhquebbeman＠theestopinalgroup.com

Good Morning all, Thanks to all who replied to my post re: the Pertec cables. The drive is operational, and I was able to restore files >from my MAGSAV-formatted tapes. Some interesting data points: the two tapes from which I recovered data had sat mostly unused since 1983. One of them I'd handed to a friend in 1988 who was working on a Prime system, for the express purpose of getting everything on disk again and then copying it to floppy disks. I never did figure out if we miscommunicated or if it was unfeasible to do so, but all I got was paper listings... but I digress. These ancient tapes had not been well-taken-care of the last few years. In fact, they were in the basement, a basement which flooded perhaps 6 times since 1996, and they had not only been under water, but had lots of nasty growth on them (mold &/or mildew). In spite of this, I was able to read all but (I think) one or two files from the source tree I'd been hanging on to. The other tape had my custom Primos command environment, Donald Slutz's custom command environment (with QED!), and my Prime-ports of Intel's MAC80, INTERP80, and PLM80. These were the items I most of all wanted from the tape. Now, the tape also (IIRC) held lots of 8080 source code that appears to be unreadable. Fortunately, I have copies of all those files on a 9-track CDC-formatted tape (actually I think it's an ANSI labeled tape, but all the files are in CDC BCD). At any rate, while I may have to write a Fortran program to read the CDC tape, I most likely can get those files. They are, however, older tapes, dating from around 1980 (I also have two 7-track tapes from about 1978). Also, I have a trick or two yet to try on the nasty Prime tape before I give up. The upshot of all this is that, if you stored the tape in a reasonable fashion (i.e. not underwater) and didn't use high density (mine were 800bpi and 1600bpi), your tapes should still be readable. It helps, of course, that this Cipher streamer was under service contract until last Dec, so YMMV. This post brings me to another question, but I'll post it separately. -doug q

Pertec Interface Cable Fun

by dhquebbeman＠theestopinalgroup.com

Help! I just received the controller to hook my Cipher streamer up to my Prime. Usually, there are little colored stick-on dots affixed to the edge connectors and the corresponding cable connectors for easy matching. Not this time. I've briefly looked at the Pertect pinout as per a short document on John Wilson's web site. However, I didn't study it enough to have a feel for what happens if the cables are hooked up backwards (ie simple non-function versus a smoke-releasing exercise). Does anyone know what happens under these conditions? tia, -doug q

HP 85 stuff

By the way, this weekend my I/O ROM started to go flaky; on power up, it reports an error 112, which is a checksum failure. I remember that this happened before and reseating fixed it, but I haven't had luck this time. I tried other slots in the ROM drawer too. Guess I need to pry open the ROM capsule and have a look. This is weird, because both the pin and the through-hole that make the contacts are gold-plated; they were made to last. I am afraid that this is a case of bit rot :-( . carlos. -- Carlos Murillo-Sanchez email: cem14(a)cornell.edu 428 Phillips Hall, Electrical Engineering Department Cornell University, Ithaca, NY 14853

Price of our hobby

by xds_sigma7＠hotmail.com

Well I can't be silent on this one... I'm broke as all hell, but I don't care.. I should probably be in college right now but I'd rather spend 3K to get a bunch of Interdata's and Perkin-Elmers... my other car is taken apart and I ought to spend money on fixing it but I don't.. Sure, maybe these aren't "good" choices, but whats important is that they ARE choices, I CHOSE to spend my money in such a way, and I live with it. But I work, I pay my bills, and hey, I could easily go to college if I'd get off my ass and work at it.. If you want to just to sit around and bitch about how poor you are, go for it, you won't get my sympathy. I know its entirely in my own power to determine how much money I have/make, so I don't complain.. If you're complaining, you probably don't understand that.. Besides, you could have loads of money if you spent the time you spend bitching working instead... Just my 2K worth...
