Searching for HW manual for HP card reader

by go＠ao.com

I'm looking for a manual (hardware / service / etc.) for an HP "9869A Calculator Card Reader". Just for clarification, this is a 50 pound table-top beast from the mid-70s that seems to be a full 80/40 column hollerith. Has 117v primary and a 34pin "ribbon" ("centronics-style") connector for I/O. I can probably make it "go" without docs, but it will be easier to repair and adjust if I have the specifics. Of course, the usual offer of payment for copies or (preferably) originals is in effect. Thanks for any info, Gary

Annals of OS and network history

by allisonp＠world.std.com

<2)Let's take the GRiD server as an example (I have never seen a GRiD < machine, BTW). How does it differ from any desktop system? Too broad a question. What is a desktop system? I can come up with several that might surprize you. <3)Have there been any machines that made extensive use of a truly < unusual architecture? What I am looking for is twofold: I am < interested if anything ever used a neural network-like arrangement, < and I am interested in something that had a processor that < interacted w/the user and a separate one to do the processing < (ie a real-time system capable of doing all that a normal one can) IS there one or three questions in there? yes there have been some very unusual machines like transputers, connection machines, vector processors, Turing machines. the latter half of your question is too broad. My z80 s-s100 crate would qualify as the OS was distributed over several z80s but only on had the user interface. The Vax-11/780 had a qbuss PDP-11 as a diagnostic fromt pannel. An xterm on an eithernet to a server could even qualify. Allison

Off on my travels...

by Philip.Belben＠powertech.co.uk

I have, at some what short notice, been told I am going to Taiwan tomorrow (for two weeks). :-( I shall be able to redirect my e-mail, but past experience of such things shows that I usually get my list subscription forcibly set to "postpone" after about a week under such conditions. However, (and this is the real point of the message), I shall probably have some space for souvenirs on the return journey. Does anyone on the list know of _any_ Taiwannese computer equipment which could be considered a classic? (Preferably not a PC clone!) Philip.

Wanted for the "carcass"

by william＠ans.net

It looks like I am now the proud owner of a LINC-8 carcass - stripped of everything but the front panel, backplane, scope, supplies, and core stack. The LINC-8s are interesting machines in that they are a PDP-8s (staight-8s) with strapped on LINC processors. They were made for a few years in the 1960s until the PDP-12 came about. I am looking for ANY of the small DEC Flip-Chips in the R, S, B, G, A, or W category (I do not yet have numbers). These are much smaller than the more common modules found in later PDP-8s and -11s, but still have the familiar plastic handles found on the M series boards. These have no ICs on them, but may have weird looking hybrid grey SIP packages (at least I have seen some on R107 modules). Any leads would be appreciated. Thank you.

I'm surprised the IBM drive caused such comment. All I was re-iterating was what the guy said "an original IBM 10Meg drive" - and as I saw IBM embossed on the front black plastic cover part, I figured thats what it was. It's just a 5" or so hard drive, and nothing special. Unless I'm mistaken, which is possible, as I don't know my stuff!

what are these cards?

by adavie＠mad.scientist.com

I picked up two cards rather than having them trashed. They're approximately square in size about mmmh....20cm to a side. I counted about 73 or 74 pins on the connector on one side of each card, the other side a solid block connect. The 1st card is labeled "Q050 DUAL TVT" and has a MCM2708(?) eprom and a 10 pin output port, whilst the 2nd is labeled "Q025 16K RAM". Were these worth rescuing? I can do images if really necessary.

Now it's possible that one of the independently owned dealer stores held and advertized other machines. Even the Radio Shack computer centers didn't start opening until the beginning of 78. The trs-80 was mid '77 and Tandy did nothing in computers before that. Allison

1978 Tandy Computers Catalog

I've been revising my web site a bit recently. One of the things I've added is the entire 1978 Tandy Computers catalog which features such things as the IMSAI 8080, Sol-20, Vector 1, etc. I don't know about you, but aside from this one catalog, I had no idea that Tandy ever sold anything like this. At any rate, the whole thing has been scanned and put on my web site. I tried to keep the page images small so they don't take forever to load, but it means that you can only read the tag lines and prices. Still, the pictures and prices are fun to look at. Take a look and let me know what you think. If there is sufficient interest, I might go back and scan the pages at a higher resolution and link the bigger images to the current ones. Also, let me know if you see any glaring errors on my site; I'm still tracking down some minor formatting problems, but most of it should be fine. Just pick the "classic computers" link on the first page and go from there to see the catalog. Hope you enjoy looking through it as much as I did! -Bill Richman bill_r(a)inetnebr.com http://incolor.inetnebr.com/bill_r (Home of the COSMAC Elf Simulator!)

OK, despite your warnings, I pulled my AT motherboard out of its case and put it into the PS/2 tower case. It fits reasonably well physically, but I AM having a bit of trouble with the power supply conversion.

What is it, and what would I need to hook it up to for the PSU and MB to think that the power is good?

DEC PC 100+ FS/TRADE

I have a like new, great condition DEC PC 100+ (Rainbow?) with Seagate St412 10mb hard disk and dual floppy. One problem...NO monitor, NO keyboard. I'm sure these can be located though. The power supply case indicates a manufacture date of December 14, 1983. The unit looks as though it just came out of the box, other than the little DEC plate in the upper left corner of the front missing. The other one that says "100+" is intact though. I have no idea why this is missing. Make me an offer. Cash or trade or a combination. I'm always looking for PC components such as internal/external cdroms, sound cards, SIMMs (30 or 72 pin, parity if possible). Best offer gets this one.

Vacation Finds

by foxnhare＠goldrush.com

From: Ethan Dicks <erd(a)infinet.com> Subject: Re: Vacation Finds... >> >> Have been on vacation since Friday and still have a couple days to >> go... From the thrift store outlook in the area things are improving >> again (I guess people are starting their pre-spring cleaning) >> >> What I passed up on... >> PET 8032, 4040 dual drive. >Agggggh! I'd *love* to replace my long-lost 8032. [snip!] >Anyway, rambling aside, where are you on vacation and is the PET still there? >-ethan That was in Modesto, CA, (My vacation this time is closer to home). I think the proboability of those units being there are good (since most of the local 'thrifters' snag the IBM, Mac, and Amiga machines that show up). I would have gotten them myself but those PETs take up alot of shelf-space (which is limited for me cause I have several PETs already), and I was pretending to be strong (of course if it were an original PET, an 8x50 dual drive or a B-128 it would have been bought. :) That chain of thrift stores (they call themselves Thrift Center Thrift Stores) are interesting, on Wednesdays and Saturdays they have 1/2 price days and with their sometimes low prices you can pick up some really inexpensive hardware, they also strangely have been a good source for Atari 800s. Yesterday on our travels, we took off to Sacramento (California's state capitol) and discovered in our wanderings SEVERAL THRIFT STORES (Many within a square mile on just one street.) But given the time we didn't stop, *sigh*, but we now know where to look next time. We did stop at a warehouse sized used book store (on Power Inn Road) most of the stuff is discontinued school texts, some assorted stuff... Not much computer book pickings there unless you have an IBM, Apple II, or a Mac (finding quality older computer books almost the most challenging task only after finding software.) Been wandering the valley for most of this last week and plan to rest out at least today and possibly tomorrow before work on Monday.

Acquired Laser 50 (mail trades DO work)

by archive＠navix.net

To Greg Troutman: I received the Laser 50 in the mail today... just as promised!! Thanks a ton, and I hope you received my end the bargain as well? To the list, I posted this here just as an example that there are successful trades that take place because of the correspondance on the list. Greg got in touch with me because I posted information about some Apple cards that I had. We talked a bit, and decided this would be a fair trade, neither of us had worries that the other wouldn't come through on their side of the deal. It turns out we both sent our hardware out the next morning, and 2 days later I received mine! Boy Greg, I hope you got your ok... let me know. Anyway, that's all. Just some publicity that trades can go right, after having some bad experiences in the past, this re-opened my eyes to the possibility of doing more often. Thanks, CORD COSLOR -- ___________________________________________________ | Cord G. Coslor : archive(a)navix.net |\ | Deanna S.

Datanumerics DL8A is here! Have a peek @ ...

by adavie＠mad.scientist.com

Well the bottom line is... I'm not an electronics guy. The option I will be following is getting the 1702A EPROMS copied and a) backed up to several media formats b) duplicated to new 1702As. >I supose the solution is for him to build a 1702 reader (which is a lot >simpler than the programmer!) and to read the EPROMs himself. >The ultimate solution would be for somebody to program a 'spare' 1702 >with a known byte sequence, and use that to test the homebrew reader. A >lot of work, though. No, this isn't a solution. I'm a software guy - I'll re-engineer the 8080A code if and when necessary, but there's no way I'm going to build hardware for this thing. I just want to copy some EPROMS... not delve into clever engineering to make them redundant! By the way, I have found several 8080A disasemblers for MSDOS. THere are quite a few websites around carrying such goodies. > Or the one that's >X-rayed with a sufficient dose to damage the chips, or the one that's >lost, or whatever. Is the X-Raying a valid problem? Will X-Rays further damage already fragile EPROMS? As I said, I may have found myself four 1702A EPROMS, the only problem here is getting the code from A to B. Maybe the ideal solution would be for me to borrow a 1702 reader and do the job over here. That way, the irreplacible EPROMs don't travel at all. Cheers A

Datanumerics DL8A is here! Have a peek @ ...

by adavie＠mad.scientist.com

OK, I've kind of settled on an approact to restoring the DL8A. I figure I'm completely unqualified to do any of this and so will rely upon advice and help from those of you who are. I think the first and most important step is to back-up the extant 1702 boot program. I've been thinking about this one (re: bit rot); would it be possible to get a disassembly of the code to see if it looks OK? It can't be too big - only 4 eproms total. Does bit rot proceed on a bit-by-bit basis, or are whole segments knocked out at a go (ie: bytes/multiples)? I presume that it will be possible to restore the boot program if there is some significant part of the eproms intact - opcodes anyway... The disassembly should give some clues as to operation of the machine, too. So, firstly I ask if anyone with a 1702 programmer who would be prepared to handle copying these 4 eproms for me to wave their hands in the air. I'll also need 4 of the 1702 eproms, so would appreciate anyone with those to also wave their hands. And finally, I'm looking for a PC based 8080A disassembler. My plan is to pull the chips and airmail them to a kind volunteer. Actually - although I don't have a lot to spend - I will be most happy to pay for the preservation (restoration?) of these data. I think its important. I do believe this machine is possibly unique; certainly rare - and worth restoring properly. I would note that the cosmetics are near flawless; this bodes well for the electronics inside, no? Cheers A

RSTS systat. Here's the proof! It works!

by DSEAGRAV＠toad.xkl.com

Just a clip from the lineprinter: Ready sy RSTS V8.0-07 GALAXIA status at 04-Mar-98 03:06 PM Up: 5:07 Job Who Where What Size State Run-Time Pri/RB RTS 1 [SELF] Det ERRCPY 5/32K SR 1:47.7 0/6 BAS2F 2 [SELF] KB0 SYSTAT 13/32K RN Lck 1.3 -8/6 BAS2F Busy Devices: None [clip...] I've deleted most of the old accounts - The disk was at 8% free when I got it, now it's at 88% free... The accounts remaining look like they have system stuff in them, or are refrenced in the start-up files. I'm backing them up to DECtapes, then deleting them to see what happens. If it runs a month without the files on the tape, I wipe the tape. (Write nulls over it) I'm moving the 44 to school, there I'm going to attach it to the nameserver (Linux) and kludge up something interesting so that people can telnet to the RSTS without having to have accounts on the Linux box. Right now I'm working out a plan with the 23+. The move is scheduled for Monday. Fun! I get to lug the RA81 up a flight of stairs! :) Oh, and does removing the account (With REACT) kill the directory by NULLing over it, or do I have to go do something else to make sure they're gone? I did see a few accounting-type things in the [5x,*] area, so I killed them all sight-unseen. The system runs OK now... Kermit is still here, I assume I can keep that... OPSER and the batch stuff are missing, and the OS source has been removed, but if Kermit works I may be able to go find some nice person with 8.0-07 and get the files needed. I renamed the machine GALAXIA, and made a copy of the old Monitor .SIL so I can kill those too. Basically now, without some real digging, you can't tell where the machine came from. -------

8 bit ATARI disk compatability with standard DD/DD drives

by jmg＠iac.net

Several weeks ago I posted a question about whether a standard PC DD/DD drive could read/write ATARI floppy disks. I got one responce which was in the negative... however, at the time the comp.sys.atari.8bit faq wasn't available from my news server (both comp.sys.atari.8bit and news.answers). Well, it is now and I have a correct answer. Check: http://www.faqs.org/faqs/atari-8-bit/faq/ Subject: 11.2) Can I read/write 8-bit Atari disks on an IBM-PC? There are several programs that allow an MS-DOS system to work with an Atari-format diskette. The following require a DOS and disk drive on the Atari end capable of the SS/DD 180K format: [... details snipped for brevity] Guess it's time to get DosEMU working again. ;-) --jmg

Apple IIc

by jmg＠iac.net

Well, I scored an Apple IIc with an external Floppy drive, Imagewriter printerer, and small composite green (maybe 9"?) monitor. $20 bucks. I also got some disks with it, but no games - mostly old nibble magazine disks. This thing has a serial port on it, anyone know what the pinout is and if these ports are compatible with Macintosh adapters? If not, what's the pinout and can I buy the DIN plug from Mouser? And hell, while I'm at it, where can I find a terminal program with x/y/zmodem capabilities? Is there anything like XIO2PC on the Atari for the Apple? Anyone know of a web page which documents DOS commands? Gee, I'm just full of questions. I'm still looking for a cheap source for DD/DD 5 1/4" floppies. The office supply store down the street wants $10 for a ten pack and I have to special order them, while $10 will get me a huge box of HD 3 1/2....grrrrr Thanks! --jmg

TRS-80 Model II

by lwalker＠mail.interlog.com

I've searched the world web over ,but never did I find...... There seems to be a lot of info on Mods. 1,3,100,Coco etc. but nada on this beast. Any sites I might have missed ? Merch , Cord ? What I have is a TRS Model II with 1 internal 8' fdd and 1 external fdd , 3 humungous 5Meg hdd ( about the size of a large XT) , K-B , TRS model 7 modem , and a box of 8" disks with CP/M 2.2 , TRSOS, Scripsit and a bunch of other prgms. When I boot up with or without an OS disk I get a "boot error ht' msg. The dd spins up and sounds like its loading. Could it have been set up to boot off one of the hard drives ? I'm really a novice with TRS-80s but have Coco 1 and 2 in my collection and a Scriptsit cart. Is there something I'm not doing ? ciao larry lwalkerN0spaM(a)interlog.com

That's what you would referr to as using proven technology! This reminds me of a story about the HP calculators. When the HP 35 calculator came out some of the US Army artillery men at Ft. Sill saw how fast they were and their accuracy so they put in a requision to buy a bunch of them. The Department of Defense liked the idea but they had to have a feasibilty study to justify the purchase, so they spent $150,000 for a study that took two years and end the end the study did show the costs of the purchase to be justified. Next, the army went to HP to buy some HP 35s but they found out that the 35 had been discontinued and had been replaced by the HP 45. They tried the HP 45 and found that it was even better, so they requested that the HP 45 be purchased instead. Again the DOD liked the idea so they commissioned another $150,000 study to justify the purchase of HP 45s. After a year and a half, this study also found the purchase to be justified. The army then went back to HP to purchase their HP 45s and .... You guessed it, the 45 had been discontinued and had been replaced by the HP 55. So the army requested that HP 55s be purchased. The DOD commissioned a third study (only $100,000 this time, the beltway bandits had this down pat!) to justify this purchase. This time the study only took a year. Again the army personnel rushed to HP to buy HP calculators, only to find out that the HP 55 had been discontinued! The artillerymen gave up and went back to their charts and tables!

Calc wars

by maxeskin＠hotmail.com

Although recent world-wide test results have proven otherwise, the US board of education seems to think that calculators improve students' minds (I feel that the insane amount of money that schools put into technology these days is better spent on books and teachers). Therefore, in our school most seniors and juniors either own or rent a TI-8x. The TI-83 is the one that the school actually promotes, but TI-85s are often stole...ahem....seen as well. My friend is probably one of the few there to have a TI-92. I'll bet it could run System 1.0 with a few modifications ;) >I wonder what the odds of finding a ti-85 are and cost? They are hackable >from what I gather. > >Allison PS That OS I mentioned earlier is essentially Win3.1 for TI. It is a concurrent windowing interface.

I was stunned tonight to look under the motherboard of this machine and find that it is totally wire-wrapped. Amazingly neat, but wire-wrapped and socketed - every single chip. Finding paths in this thing is going to be very very time consuming! This computer must have been extremely expensive in its day - the amount of work involved is incredible - not having made anything like it, I'm only guessing... but I'd guess many tens of man-hours. Coincidentally, I was on the hunt for another machine (Mattel Aquarius) and the owner and I got into a discussion about S100 machines - he has a garage of them, apparently (he used to design them) - and I told him about the EPROMs (1702As) and how I was going to back mine up - and he said "I have four of those things!!!" Yes, before you ask, I am going after those S100 machines :) Cheers A

Found a Apple IIGS UPgrade

by jrkeys＠concentric.net

A few weeks back someone asked about Apple IIGS that looked like a IIe, well a got one today at an auction for free. The guy that won the bid on box of electronics gave it to me but he gave the color monitor to someone else :-( It looks just like a IIe or II case except for the IIGS logo on the lid next to the apple name. On the bottom it says Apple IIGS Upgrade Model No. A2S6001 with a serial number following that. No date is on the bottom but the mother board says Apple IIGS on it also and has 7 slots on the rear another to the side with a memory expander in it right now. It has the standard 15pin monitor hook-up like the Mac and round phono jack. The rear looks like a Mac LC or IIci. No date mb either that I can find. Have not fired it up yet. Also got a Tandy 1000RL for twenty with kb and mouse. Got a number of manuals, tech ref's and other written goodies also >from .05 to 3.00 each. Got a apple ext. 3.5 FDHD drive for free at the scrap yard but have tested it yet. A IBM 8535-312 missing the memory for $15 will fire it this weekend. Picked up a NeXt N4000B 17" monitor for 16 and a new NeXt software rel 08.30 chip with a date 1988 and serial number of 000A81. Well that's it for I got more stuff this week than I can list here for now. Keep Computing John

For quite a few years, one bit of folklore that has popped up on a regular basis is that of old IBM dinosaurs running our air traffic control system. Well, I was just wasting some (work)time now looking at some recent threads on <bit.listserv.ibm-main>, and it is fairly clear that the 9020s are now all gone after probably too many years of service. The interesting thing is that the machines that replaced them, 3083s, are also now considered classics. William Donzelli william(a)ans.net

Slightly on topic... tip for linux?

by DSEAGRAV＠toad.xkl.com

Does anyone know if there is a tip for Linux? (The comm program?) It had an option to go to another port if the one needed was busy. Minicom can't do that. I would like that ability, 'cause when I connect the 44 here, I'd like to have people telnet to a port and get passed straight into the DH plug, via pip, without having to have an account on the PC -------

VSchool: (Directed at kids, but adult's welcome too!) Just an idea...

by photze＠batelco.com.bh

Hello. Several days ago, under the demography thread I briefly mentioned the "VSchool" concept. So, for those interested, here's what I want to do. Background info: The VSchool idea came from two needs: my need to create a virtual community, and, more importantly, the need for children (ages pretty much 6th grade-12th grade) to be able to learn at their own rate. At the subjects that they're interested in, or feel weak in. So, I then think of a place where all this could take place, actively, and freely. Now, Bahrain is far to remote to even begin to demonstrate something. Also, it's got limited resources and views. The Internet. It's used by far more than the population of any city, and equal to that of many countries. How I plan to pull it off: This is the area that I don't have to spend 50 lines telling you what CGI is and does. So, I'll use CGI (anyone got info on this?) to put up forms, (I can't program it... sorry...), and then we can make a chat room of some sort, possibly a Javascript password form. (Ok, so I'll need lots of help) So far, the best deal that I've seen in web hosting is digitalchainsaw (at http://www.digitalchainsaw.net) Anyway, we'll have two functions: Students will "enroll" (for free), and then they'll choose their area of expertise. There, they will be considered a teacher. In other areas, they'll be considered students. Teachers will work together to develop a curriculum. Then, they'll work together to teach others. I want to have a copmputer history as well as a computer interest group. I'm asking for your help. You would be considered a partner, if you wanted. Thanks, Tim D. Hotze

Still, nice to hear from another one. (On the other hand, there is probably a strong correlation between bassoonists and eccentrics, and a stronger one between this list and eccentrics.) Philip.

Vacation Finds...

by MPritchard＠EnsembleStudios.com

I had a working CMB 8032, and one day a couple years ago, saw an ad in the paper "Wanted: CBM 8032". A couple in their 70's placed it. The wife is a writer, and not a computer user, and only knew how to use her CBM 8032 which was 15 years old and failing. I brought my 8032 (which I had set up in my office, after it fell from a high shelf and put a dent in the hood of my car) to them, swapped it out, swapped roms (mine had some sort of add-on board) and tore-down, cleaned, and re-assemble the keyboard for them. and off they went. I think they did have all the manuals and stuff for the computer, disk drives, and printers. alas, I don't have any PET computers anymore. > -----Original Message----- > From: Ethan Dicks [SMTP:erd@infinet.com] > Sent: Thursday, March 05, 1998 3:28 PM > To: Discussion re-collecting of classic computers > Subject: Re: Vacation Finds... > > > > > Have been on vacation since Friday and still have a couple days to > > go...

Calc wars, other calc stuff, my own previous post (uVAX/GPX)

by cchi＠lle.rochester.edu

Hello all... me again. I apologize for writing twice in one day, but I've requested "Digest mode" and am finding several topics I can respond to. I should've waited before sending the previous message, but will now be aware of this and will cover ALL current topics of my interest in this ONE note, to save you all the pain of seeing SEVERAL messages from me. (If you'd RATHER have several separate messages, someone just say so...) 1) Joe <rigdonj(a)intellistar.net> quotes a message quoted by someone else, in which the original author says that "... it's the HP25 that I still prefer..." Original author, whoever you are, I wanted to let you know that I have a set of original manuals and -- if I can still FIND it -- the AC adapter, left over when my own HP25 was stolen from me one day in high school -- circa 1978... If you're interested in these items, e-mail me. 2) At a Hamfest last spring I acquired a TI calculator -- I forget the model number right off; I wasn't expecting to talk about this today, but it's the programmable one that reads-and-writes those magnetic cards -- along with programming manual(s) and the external PRINTER, not to mention a fistful of the magcards. The only trouble is, instructions stored in program memory randomly get altered, i.e. the memory is no longer reli- able (hmm, just like ME!). Is it "just old," and there nothing that can be done? Or can it be repaired? Much obliged, for any info anyone can provide. 3) At that same Hamfest last spring, some guy found out I was "into" calcu- lators, HP in particular (notwithstanding that TI-whatever I'd just bought), and talked my ear off about some "latest and greatest" HP calculator that "did it all," allowing you to mix "ordinary" calculator statements, BASIC, and C syntax "all on one program line," among many other things. I have forgotten the model number, so if anyone recognizes this description and can TELL me the model number, and of course where to find out more about the thing, I'd really appreciate it. 4) My HP-33C battery doesn't hold a charge anymore; please advise. Joe Rig- don...? 5) Re: that uVAX stuff I mentioned in my PREVIOUS message: I'd be MOST inter- ested in anyone who could trade "my" stuff in London, for "his" set of the "same" stuff in the US! I can provide a more detailed itemization of what I have. Chris Chiesa

CLASSICCMP partial digest 346

by cchi＠lle.rochester.edu

Hi. I'm new. But enough chatter. I see Bruce Lane <kyrrin(a)jps.net> is interested in uVAX II GPX video boards... That brings to mind the set of VCB02 boards-cables-and-keyboards which I've got "stranded" in London after a failed attempt to get them to Rochester, NY, from mid-Scotland "on the cheap." I'd love to hear from anybody who a) can get them from London to Rochester (or even just to the USA) cheap or free, or b) is IN or NEAR London and has an interest in them and something to trade which is already IN the USA... I know this is a long shot, but hey, I had to make a grand, if weird, entrance... Chris Chiesa cchi(a)lle.rochester.edu

Mac 512k complete set FS/Trade

by rhblake＠bbtel.com

In addition to the previous Apple/mac items message, I also have the following fine machine for sale or trade: --MAC 512k system which includes cpu/monitor unit with original 400k internal floppy, enhanced keyboard, mouse, printer, manuals, software and applicable cables. The unit was owned by a friend of mine since new and only needs a repair or replace of the floppy drive as it's getting old and sometimes doesn't read the disk, does other times. Great condition otherwise. Entire set $75.00 plus shipping or will consider trades (as mentioned in previous) or other PC compatible parts. I'll also include text on upgrading RAM to 1mb using common DRAMs piggybacked. Contact me if interested by direct reply... -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 / Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

Apple Items FS

by rhblake＠bbtel.com

To update everyone, the Vector 3 has a new home and is on it's way there. I have the following Apple components for sale but will trade as well. You have to pay shipping though either way. * Apple ImageWriter II color dot matrix printer with good color ribbon and mini-din to 25 pin sub-d male adapter cable. The printer itself has a female mini-din connector. $40.00 plus shipping * Apple 5.25" external floppy drive set. Two drives that chain together, marked Drive 1 and Drive 2. Excellent condition. $25.00 plus shipping * SIMMS - 30 pin 1 mb non parity for Apple and Macs that utilize 30 pin SIMMs, not SIPPs or DRAMs. I have 8 of these. Seimens type with 5 large chips and two small chips. $8.00 for the set or even swap for 8 PC compatible 1mb 30 pin type. Items I might trade for: -CDROM drives, internal or external. IDE, SCSI or proprietary. Proprietary drives MUST include applicable adapter card. All should have any available manuals and software if possible. -Sound cards. MCA, ISA, VLB, etc. 8 bit or 16. Again, it would be best to have any available software or manuals if possible. -SIMM memory - 30 or 72 pin parity or non-parity, but MUST be useful in PC's and compatibles. I have no use for the Apple/mac types (hence the sale of the above). -486 motherboards, with processor.

I'm back! Now, who...?

OK, I'm back from JPS Internet. Neat service! Now... based on the latest digest I got, it appears that someone (I'm not clear just who it is) has some MicroVAX II GPX video boards, cable, and mouse available for trade. Please get in touch with me if these are still available. The cable alone is worth the effort for me to obtain.

I was downtown and there in the front window of a computer store was a Sorcerer run a hi-res demo of liquid flowing out of a bottle. Very impressive, I wanted one.

Info needed on Microbee, System 80, Pencil II, TI 99/4

by scott＠isd.canberra.edu.au

I need some information on some old micros I have in my collection. They are all Australian models apart from the TI, although some of them made it overseas. Pencil II --------- The sticker on the base says this machine was made by Soundic Electronics, although I believe it may have been distributed by Hanimex. I need information on the power supply. I have been told it's 9.9V DC 1A and 17.7V DC 500mA, but I need the pinouts for the 3-pin DIN socket the supply is meant to connect to. Microbee -------- I believe the DIN socket at the rear right-hand corner is a combined power supply, cassette in/out and composite video out socket. Can anyone tell me the pinouts? System 80 --------- Originally this had an RF modulator, but the one I have has been very heavily hacked. Can someone give me the pinouts for the video DIN socket? TI 99/4 ------- Note that this is the 99/4, *not* the 99/4a. Can someone tell me the power supply requirements and pinouts? It is *not* the same as the 99/4a. I *think* it may need +5, -5 and +12, but I'm not sure.

Strange PCjr found

by SUPRDAVE＠aol.com

yes, i've seen one of those funky pcjr models too. i wish i had bought it just for the curiosity factor. i dont remember what brand the expansion unit was though. my particular pcjr has another drive in an external case with its own power supply and a cable going to the unit like an apple ][ In a message dated 98-03-05 18:37:23 EST, you write: << I was in a thrift store during lunch and saw a PCjr which had a second box attached to the top which contained a second floppy drive. This almost doubled the height of the system and there was a larger side car type box on the side as well. Any ideas as to what this may have been? Was it just for adding a second floppy maybe? I'm thinking about going back by and picking it up. They also had a VIC-20 with the VIC version of the floppy drive which I think I grab as I don't have one of those. >>

Vacation Finds...

by foxnhare＠goldrush.com

Have been on vacation since Friday and still have a couple days to go... From the thrift store outlook in the area things are improving again (I guess people are starting their pre-spring cleaning) Stuff I got: - Timex/Sinclair 16k RAM unit with a few cassette programs for it. - Given to me, a COMPLETE IBM PC (read model 5150, the first IBM PC I think... (he had run this one until very recently when he got a new multi-media system...) The computer has dual floppy drives, a cassette port and everything! Computer, Monitor, Printer, (all IBM) IBM DOS and other disks and all manuals! (Wordstar, Microplan, BASIC, etc. etc.) Haven't powered this one up but the previous owner says drive A has problems, but once running he could work off of B. (if anyone is interested in it an willing to pick it up, I will pass it along, otherwise it will go with me to VFC 2.0 (Hey, Sam, wanna raffle off a COMPLETE GENUINE IBM PC?) What I passed up on...

Sol-20 revisited

by allisonp＠world.std.com

< Thanks Jim. Have you replaced the video ram in the Sol-20 before? < Also, do you know if parts are still available or will I have to < cannibalize from a similar vintage pieces part? < < Marty If it's a bad video ram swap it with the one next to it, if the pattern changes the ram is fried (I have tons of them). If the pattern doesn't change is likely a bad 74ls157 or 8097(74ls367). the test for a bad '157 or 8097 is to swap it with another on the board and see if the symptom changes. The fact that you've seen different patterns says the video rom is ok. Try popping out and reinstalling all the socketed parts and boards. You may have a crusty connection. Allison

Sol-20 revisited

by Marty＠itgonline.com

Thanks to all for the hints, help and tips on the problem of getting this Sol-20 running. I fired this up last night but the screen didn't appear as I remember it last time> I must be losing my memory. All testing was done with the Sol-20 barebone, no S-100 add-on cards installed. The screen appears as such: $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ >$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ The prompt > is at the beginning of the second line, and this pattern is repeated in all 16 rows, save the second where the prompt appears. The upper case light and local light are on, the shift lock light is off. The keyboard doesn't respond except for the - key which is to the left of * on the numeric keypad section on the right. Next, I disconnected the keyboard cable (after powering down for a minute or so) and get the exact same result as above, less the upper case and local lights on of course. Finally (after powering off) I removed the SOLOS prom board and of course don't get the prompt > but get a new video display repeated from top to bottom of an equal sign '=' followed by a lightning bolt, this pattern repeats = then lightning bolt (I cannot reproduce the symbol) endlessly from top to bottom. I also tried a different RG62 video cable in all tests and get the same results. Thanks again for your help- Marty Mintzell email:marty@itgonline.com

Demography

by Marty＠itgonline.com

William, I'd be interested in the Sphere, SWTPC gear, etc you don't want. Thanks- Marty Mintzell email: marty(a)itgonline.com ______________________________ Reply Separator _________________________________ Subject: Re: Demography Author: classiccmp(a)u.washington.edu at internet Date: 3/5/98 12:38 PM Well, lets see. I am 28 or so, living now in Carmel, NY (about fifty miles north of NYC), and like old things in general. Mostly. I am employed by one of the ISPs (originally the first ISP - the NSF) as an engineer. As you can probably tell by now, I tend to pick up the scraps of the network. I originally collected old radios. I had a small collection of consumer sets, some working, but dropped the hobby when two others came into my life - computers and old industrial/military electronics. The latter is simply from my consumer radio collecting days. The computers, however, probably started with the Apple II, like so many other kids in grade school. The first computer I ran into is my old DEC PDP-8/S, purchased "thru" a hamfest back in 1986. I was eyeing someone's PDP-11 boards (I was already a hamfest regular), and a man approached me with an offer I could not refuse - for $5, I could have a real, six-foot tall computer. I still have the machine. After that, I started getting others - mostly PeeCee and small mini machines. Sometimes they were pulled from dumpsters, other times they were purchased for a song. Right now, the collection consists of a PDP-8/S, PDP-8/E, PDP-11/23, PDP-11/34, Interdata 14, IBM S/1, IBM 5100, Sun 3/50, 3/60, 3/280 and 4/280, SPARCstation 370, SGI Iris 2500T, IBM RS/6000/T3B, and HP 2100A. Some machines work, some need work. There are parts of many others, but I am not counting those. I also have a bunch of ancient Sphere/SWTPC/Exorsisor stuff that I need to get rid of (I have no interest in it). Most of it will migrate to RCS/RI (so Allison can play with it). In addition to old computers, I collect old Naval radios and radar sets from the 1930s and 40s, as well as vaccuum tubes. At this point, I do not know which collection takes up more mass, as some of the shipboard radio transmitters are six foot monsters as well. Look at some of the old serials from the 1950s - they tend to show up as props in monster labs. And I do not play bassoon. I also voluteer time as part of the restoration crew on Battleship Massachusetts - a place with _real_ computers. Sorry guys, but engineering and craftsmanshipwise (is that a word?), the mechanical fire control computers are far more impressive than any of the digital stuff.

That was less common then, though maybe not for the folks on this list. My dad had a "portable" Teletype model 33 (I have it now) with an acoustic coupler modem. He had accounts on GE timesharing (BASIC) and the nearby University of Wisconsin Burroughs B5500 (I used WIPL, a little like FOCAL.) I got a BS in EE and MS in Computer Science at UW, where I ran PDP-11's etc. in the CS lab. Have mostly worked at Intel in Portland since then. No time for more bio now, but there is some more info on how I started collecting on my web site.

by jthiemann＠castleton.com

While we're at it (the buisness of veering grossly off-charter), who else here collects electronic music equipment of about the same vintage as the computers discussed here? I have a Korg Poly-800, Yamaha DX-7II, 2 FB-01's, CS-01, a Sequential SixTrack, 360 Systems MidiBass, and a homebrew MIDI interface to hook some of this to my Amiga. I have grandiose plans (ok, ok, not _so_ grandiose, but everything is relative these days...) to rip the 6581 out of my C64 (or better yet, find an old otherwise nonfunctional C64 and rip the 6581 out of there) and hook it up to a 68HC11 SBC I designed a few years back (the company I used to work for is still using and occasionally producing these) and controlling it (the 6581, that is) via MIDI as a cheap-o (and physically small) analog synth. (Cause let's face it, that's what the 6581 is...) BTW Any of you UK guys have collections of the old E&MM magazine? I'm missing 1 or 2 issues in the 84 (83?) season... -------------------------------------------- Joachim Thiemann DSP Coder, Castleton Network Systems I doubt therefore I might be. > -----Original Message----- > From: R.

DEC GPX II Q-Bus boards

by jthiemann＠castleton.com

I think I have that card set (but not the roms - but I do have a spare ka630 board) with full instructions. I can dig up specifics over the weekend, when I'm back in Montreal. My uVaxII does have the ability to act as an X client - I tried it, I have the 3 Tk50 Ultrix distribution set (but who wants that if you can have NetBSD?) I think it can drive the GPX cards too, but have never seen it do so myself - I don't have a monitor to hook up to it. If anyone wants the cards (the GPX and the spare ka630), they're up for grabs - either for sale or trade since I'm not doing much with the VAX (I like my Sparc better) -------------------------------------------- Joachim Thiemann DSP Coder, Castleton Network Systems I doubt therefore I might be. > -----Original Message----- > From: allisonp(a)world.std.com [SMTP:allisonp@world.std.com] > Sent: March 4, 1998 22:06 PM > To: Discussion re-collecting of classic computers > Subject: Re: DEC GPX II Q-Bus boards > > <I have a three board set of Q-bus cards plus the boot ROM for a uVAX > II, > <dated from 1987, which supposedly turns a VAX server into a > workstation f > <DECWindows.

It contains 18 chips, 10 of which say AM9016EPC & 8248FMP. The other chips are labeled SP225, SP229, P218, SP245-b, SP220, and SP238. The card also has a red switch on it. Really no other information... oh, it also has 4 led lights. Please let me know something about this! *Expansion card of some sort for the Apple //e. This is about 3"x2" as is (c) 1988 by Applied Engineering. It says ][e 64k on the side by the 'plug-in', and on the other side is says KEYBOARD. Please let me know how this thing is used! * 1.5 foot cable. Adapter of some sort. Looks like a PC joystick adapter. 15 pin male to 9 pin female. * Joystick -- called Laser Joystick. It is small has has 2 buttons on the side. I know of the Laser computer series, etc. (I have a Laser 300, some kids computers, and want a Laser 50!) by V-tech... didn't realise they made joysticks. Has a 9 pin connector on it. Does anyone know what computer this was for, or when it was made? * Some type of expansion card... presumably for the Apple. Has 19 various chips on it. Made by Data Technology Corp. Would love some more tips on what this might be.

Info needed on Microbee, System 80, Pencil II, TI 99/4

by adam＠merlin.net.au

>Microbee >-------- >I believe the DIN socket at the rear right-hand corner is a combined power >supply, cassette in/out and composite video out socket. Can anyone tell me >the pinouts? I have one of these, but I'm afraid I can't help - the version you speak of should be the Microbee 64 with the Computer-in-a-book combined disk/drive power supply etc. I only have details for the 16k version. Nevertheless I'll try digging them up and see if they help, but hopefully someone else will be able to tell you more. The manuals I have lack details. >System 80 >--------- >Originally this had an RF modulator, but the one I have has been very >heavily hacked. Can someone give me the pinouts for the video DIN socket? I can do this. :) Going on the diagram I have here, we have: 3 ---- ---- 1 / \ / | \ / | \ 5 | 4 2 where 1 is +5v, 4 is video output, and 5 is ground. I have most (if not all) of the manuals for the System 80, including some doubles here. Adam.
