I got a PS/2 Model 60 and OS/2 2.0 (1992, but still classic) PS/2: a)How do I get rid of the mold inside? b)What is the PSU pinout if I want to put in a regular motherboard? c)Is there a way to upgrade the mb to 386 with <$10 and a 386 mb OS/2: a)I installed it on a 386 w/4 MB RAM (min. requirement). It CRAWLS. Should I replace the MFM HDD w/ IDE? b)Does anyone have os/2 1.x that they could send me? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

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. Right now, he's trying to figure out the concurrent part... ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Sol-20 revisited

by allisonp＠world.std.com

<Assuming that this is electrically the same as the S100 version, then... < <The 8097 is the data buffer betwen the RAM and the S100 DI lines. It's <used on reading only. I don't see how it would affect writing to the RAM If the input is internally shorted to either rail. I've seen this mode of failure on old chips. <There are some 74LS08 AND gates that are used as buffers between the S100 <DO lines and the RAM inputs. It's possible that one of these has become <faulty, I think. Entirely possible. <There is a 74LS175 latch (well, actually a pair of them) between the RAM <outputs and the character generator. Now one bit of that chip could well <be faulty (IC6 on the S100 card, I think). Yes, also possible. <Not so. One of the most common failure modes of old IC's is that the <bondout wire between a pin and the silicon die breaks or comes adrift. If <the A2 line (pin 12) of the character generator had failed in this way - <or if the input buffer in the ROM had failed - we'd see exactly this <pattern. Also true but less likely. Allison

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

It's getting out to ME. When you got the "full mailbag" error messages, did they show up as "return e-mail" messages? That probably means that one of the list-members who should have RECEIVED your message, had a "full mailbag" and couldn't take another message.

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

Finally gone...

by william＠ans.net

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?

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

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

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
