Whilst in a self-induced trance, Tim Shoppa happened to blather: >Well, when it comes down to it, vanilla CP/M never had >FORMAT. Didn't matter a whole lot on vanilla systems, as >8" floppies always come preformatted. Yes, but what about *chocolate* CP/M? Huh? How about that, Mr. Smart-Guy??? Everybody knows that chocolate is better than vanilla!!! ;^> I'm just joking... still working & it's been a long night! Anyone here have any experience with Unix NewsServer Daemons?

The name was something like "DPC-1" | >- Change: NorthStar Horizons primarily ran NSDOS | Interesting... Many I worked with ran OASIS. B^} I guess it would have been clearer to say "NorthStar Horizons shipped with NSDOS". I'm sure most of them "primarily ran" CP/M after the owners realized how obscure and limiting NSDOS was ("cd" to Copy Disk? Gee, a DOS user would never type that by accident!) Kai

Osborne 1 prices (was: On Generations of People and Computers )

by ronaldm＠mars.ark.com

I have an Apple II Plus, with 4 (count 'em) 4, 128k disk drives, all operational. It also has a 256k RAM card, an 80 col card, and a Super Serial card along with a Microsoft Z80 CP/M card. I don't use it very much these days, except for a bit of record keeping on my video tape collection. Just out of sheer perversity, I'm using Appleworks, which loads itself into the RAM card and seems to operate from there. Also have something called the DAVEX shell, which provides a front end for a number of activities including running Appleworks. Once you get the <ESCAPE-DO THIS-DO-THAT> keys figured out, it works not half bad for my occasional record keeping. It's like most of the stuff I have around here. It came with a literal ton of software, most of which I haven't even taken the time to check out yet. Also has a voice recognition card, and an EPROM burner which are sadly stored away in my lockup. One of these days.

Funky looking mouse and other TCF stuff...

by more＠camlaw.rutgers.edu

Hi guys, just wanted to say what I got at TCF. I managed to get there at 3:45 on Sunday (15 minutes before closing on the last day of the show.) Anyway here's what I got: 2 Seagate MFM Hard Drives *FREE* 1 Sysquest tape(?) drive *FREE* the tape drive is about the size of a CD-ROM, what is it? 1 Apple IIe Users Guide *FREE* (why? I dunno, it was in the trash) 1 CBM 8032 $5 (this things got some kind of memory board that plugs into the CPU socket and a parallel interface) 1 Funky Mouse *FREE* This last thing I need help with. It looks to be about 20+ years old but I could be wrong... It is bright red, almost perfectly round, has a steel ball as the roller, 3 black switches, and says "5271" and then "DEPRAZ - MOUSE" on the bottom. It has what looks likea standard serial cable. The guy said it was for a terminal right before he threw it out. Any ideas? More importantly.... do you think I could use it on my PeeCEE? 8) Les PS what'd everyone else get at TCF?

Ward, The Model 2000 did carry the TRS-80 logo. The black/silver badge on the front of the machine, which was rotatable in case you put the 2000 upright on it's nifty floor stand, said 'Tandy' on the first line, in a black band, 'TRS-80' on the second in a silver band, and 'Model 2000 Personal Computer' in the third on another black band. This is clearly shown on the front of the 'Tandy Service Manual: Tandy Model 2000 Personal Computer'. I owned one of these machines for a number of years, but sold it when I got caught in the clone upgrade mania. Now I'm working on purchasing another. Also, I aquired an Atari XE System today, with the optional keyboard, along with two 1050 disk drives. Cute little machine, and includes the light gun. Anyone in need of a 1050 disk drive for an Atari 8bit? I don't need both, and don't have a PSU to test either out with.

At http://www.emulators.com the now have the schematics for their xformer cable on the web site, which should work with their xformer software, there is also a product called ape which is at http://www.nacs.net/~classics which allows you to connect your atari to a pc. They also have schematics and a program to run an atari disk with a pc, to copy and create disks. I have read a lot of flap about incompatibilities writing disks back and forth between the two types of drives. Of course, you could get a black box or an atr8000 and I think that would allow you to use a pc floppy with your atari. I have actually never tried any of these, I just use a null modem cable and transfer the software back and forth. Isaac Davis idavis(a)comland.com indavis(a)juno.com

ethernet and apple2GS

by jim＠calico.litterbox.com

As those of you who follow the comp.sys.apple2 groups know, there never was an ethernet board for the apple2, and the one that apple designed for the 2gs never went into large scale production. This annoys me, since the gs is certainly capable of running network applications - it comes >from the factory with appletalk/localtalk. So I've been thinking about this problem for a while. Before I go into my "solution", I should mention that I'm in no way an electronic engineer, and the odds of my even attempting to do this on my own, let alone succeeding, aren't very good. But it seemed like an idea at least worth sharing, on the grounds that maybe one of you who IS an engineer could make some bucks inventing this thing. My idea is this: build an ethernet board for the apple2 series with the following parameters: 1. it looks to the system exactly like a localtalk board, only faster. 2. it has enough brains to analyze outgoing frames to see if, in fact, what is being sent is ip encapsulated in appletalk. If so, de-encapsulate it and transmit it as straight IP. - this is a software issue, really, but it needs to happen in the firmware of the ethernet board, so... 3. It has enough brains to analyze incoming frames and determine if in fact the frame is an IP frame. If so, encapsulate it in appletalk and feed it to the system. 4. It has a way of turning all this brainpower off and being driven with a normal ethernet driver running on the host system. 5. It can do any translation between appletalk and ethertalk so the machine can talk to it's Macintosh kin. My reasoning for all the shenanigans with appletalk and ip is this: no standard mechanism exists for talking to an ethernet board in an apple2. However, the GS comes with atalk drivers in rom, and you can get them for earlier apples, and a lot of software does do tcp-ip over appletalk, assuming it's going to be talking to an appletalk/IP router downstream. Caviets: I haven't looked at the appletalk/ethertalk/localtalk protocol to make sure what I'm suggesting is sane. Same goes for tcp-ip over appletalk. There's a standard for this stuff, but I haven't looked it up yet. Anyway, that's my idea. Feedback will be greatly appreciated. -- Jim Strickland jim(a)calico.litterbox.com -- By Caffeine alone my mind is set in motion.

Non-micro classics

by carl.friend＠stoneweb.com

In the lengthy "Re: yo" thread, Mr. Ismail mentions: [double-quote from Mr. Donzelli] > > PDP-8, PDP-11, IBM S/3xx, Nova, etc. Computers were not invented in 1974, > > guys. > > Yes, I realized that. The PDP-8 and PDP-11 are definitely worthy of > mention, but did they really make the impact and have significance equal > to the Altair and the others? I'm sure you could argue to that effect. > Care to? It's probably fair to say the the minicomputer actually made more of an impact in society than the micro has. It was the minicomputer which was first affordable to smaller companies and operations; the mini was also the first class of machine available to schools of modest means. You'll find that almost every microcomputer designer was, at some point in time, touched by a mini, and sometimes their designs reflect that. One of the original Apple's designers actually held the DG Nova in such high esteem it's rumoured that he kept a picture of one taped to his bedroom wall. Billy Gates did the original work on his BASIC interpreter with stolen time on a PDP-10 (though, that can't really be termed a mini). Most of the impact, though, of the mini is behind the scenes; they made manufacturing more efficient through the increased use of CNC, made scientific experimentation more prodcutive through more accurate experiment monitoring, and found their way into all manner of hospital equipment. This isn't meant to downplay the changes brought forth by the microcomputer, which with the advent of the Internet are enormous, but merely to place the minicomputer in the light of day. The changes were different from the micro, but certainly not unimportant. ______________________________________________________________________ | | | | Carl Richard Friend (UNIX Sysadmin) | West Boylston | | Minicomputer Collector / Enthusiast | Massachusetts, USA | | mailto:carl.friend@stoneweb.com | | | http://www.ultranet.com/~engelbrt/carl/museum/ | ICBM: N42:21 W71:46 | |________________________________________________|_____________________|

You might take it apart and reseat the keyboard connector or ribbon whichever it may be. As for power supplies, you should be able to get an equivalent power supply at radio shack. Just bring the atari one in, and they should be able to match it. I can ship off a couple of disks to you with DOS, and a few games. I will check out your web page for your address, but if it's not there, just let me know where to send the disks. There is a guy here in Austin, that has a lot of atari software for sale at really great prices. His name is Rick Detlefsen and his email address is 74766.1561(a)CompuServe.COM I have bought some software and an 850 interface from him, and his prices are great. I think I paid $0.60 for a Robotron cart from him, and it even had the box and manual. I will put together a few disks with some stuff on it, and send them to you. Hope this helps.

> > How about Chuck Peddle? > > Who? (please explain!) Chuck Peddle, while working at Motorola, was on the design team for the 6800. He and a number of other engineers on the team had a number of enhancements that they wanted to make to the chip, but the higher-ups wouldn't let them. They left Motorola to form MOS Technology, and developed the 6502 line of CPUS. When Commodore decided to get into the Personal Computer market, they bought MOS. One theory is that they primarily wanted Peddle. Chuck went on to design the early Commodore machines. (I'm not sure how involved he was in the Kim-1, but he almost singlehandedly designed the first PETs.) This is mostly off the top of my head. If I made any glaring errors (or minor ones, for that matter), please let me know.

TI 99 & a good weekend

by BigLouS＠aol.com

I managed to pick up a beige, all plastic TI 99/A this weekend and if I remember prior posts this is an uncommon version of this machine. I also saw what looked like the standard black and chrome machine except that it had no chrome at all. Did TI ever make such a machine or is it a standard machine that was mutilated by some brute? I also picked up a Commodore SX64 and a Franklin Ace 1000 (a sentimental favorite of mine) as well as a CoCo floppy drive and interface cartridge. It was a great weekend. Lou

PET to S100 bus interface

by ds_spenc＠alcor.concordia.ca

I'd just like to make an update for all who may be interested in that potential PET to S100 bus device that I had sitting in storage. I pulled it out tonight instead of studying for exams, and it is indeed what was suspected. The "motherboard" (if that is the correct term) is a Vector Graphic Inc. S100 bus board. The RAM board that was being used for the PET, is a Vector Graphic Inc. 16K Static RAM board with a date of 1977 on it. The power supply says "KIMSI-PLUS Power Supply" on the back, 1977 from Forethought Products. This is all very wild, because I had no idea there was S100 stuff in this house. Anyway, the really interesting piece of circuitry is the PET to S100 interface board. It's the same size as the RAM board, and of course plugs into the S100 bus. At the top of the board is a 50-pin connector that plugs into a cable, that in turn plugs into the side memory expansion connector on the PET 2001. In white lettering, it says .----------. |_| | | |_|| | | |_| | || (<-- my cheezy attempt at duplicating the company .----------' logo with ASCII, it's HUH surrounded by a question .ELECTRONICS mark.) S100 MPA and etched into the board it says "COPYRIGHT 1978 BY HUH" and "S100 MPA REV A". The board isn't very heavily populated, compared to the RAM board, and most of the chips are 74LSxx chips. Anyone out there know more than I do about this thing? Doug Spence ds_spenc(a)alcor.concordia.ca

emulator board help

Jeff, It's way past my bedtime, but I just had to comment on this post... Believe it or not, the board doesn't have to emulate a specific 68K computer... it *is* a specific 68K computer! The board quite possibly was a system that would just use the PeeCee's hard/floppy/parallel/serial (etc.) ports and would run OS-9/68K or another viable 68K operating system of the day (Xenix?). This in itself is not new... shortly after the IBM-PC came out there was a 68000 board for it that ran OS-9. Remember, the 68K was first, and by then already had several super-powerful (compared to MS-Dog) OS's available for the platform. I have a review of one in an old copy of Byte laying around somewhere around here. BTW, put away the asbestos... it's not a flame! I'm just tired (& cranky) and don't have a bad case of run-on fingers like usual!

Software database for you collector-types

by marcw＠lightside.com

Howdy, I just thought of something. Are any of you using a database to catalogue what software you use/have for these old machines? I've got a database that came on a Big Blue Disk back around '88 called Software Indexer. It's small and all but has some nice features including cascading menus with a lot of pre-defined categories. These can be edited/deleted/added to. There's not much data entry because of the menus/pick-lists. Once you type in the name of the program everything else is a matter of choosing what's there except for the comments field. Here's examples that may interest you (jeez I sound like I'm spamming a new product here). Example/sample of menu selections: System Macintosh MFS (Old format) HFS (Current format) Lisa Office System Apple II Series Apple ProDOS 8 Apple ProDOS 16 Apple DOS 3.3 Apple DOS 3.2 Apple CP/M Apple Pascal Apple GEOS Apple /// (SOS) CP/M CP/M-80 CP/M-86 CP/M-68K Orphan Machines Timex/Sinclair TI 99/4 TI Professional Osborne Exidy Sorcerer CompuColor 2 SOL-20 Ohio Scientific Altair Cromemco Mainframes DecSystem-10/PDP-10 DecSystem-20 RSTS Multics Minicomputers IBM System 34/36 DEC VAX (VMS) PDP-11 Video Game Systems Atari VCS (2600) Atari 5200 Atari 7800 ColecoVision Magnavox Odyssey 2 Sega Master System (more) Medium 5.25" floppy Double-density High-density Single-sided "Flippy" 8" floppy "Twiggy" (old Lisa) And all the other stuff. Atari's, Amiga's, Commodore's, Intel x86, etc. Other categories/menus are Distribution & Category. All customizable 'til you run out of menu space (easy to do). Anyhind, if anyone's interested I can zip it up and send it to whoever's interested. It is/was shareware. I used to get Big Blue Disk but don't remember if I got this from there or from a BBS way back when. Marc -- >> ANIME SENSHI << Marc D.

Regular Posting: FAQ

by bill＠booster.bothell.washington.edu

ClassicCmp - The Classic Computers Discussion List FAQ (Frequently Asked Questions) v1.0 1.1 What is ClassicCmp? 1.2 Why is ClassicCmp? 1.3 What's a Classic Computer? 1.4 Who runs this thing? 1.5 Don't you know you're duplicating what others have done? 2.1 What can I talk about? 2.2 Can I talk about PCs? 2.3 Can I talk about Mini/MainFrames? 2.4 Can I post advertisments? 2.5 Can I ask people to give me their computers? 2.6 Can I ask for help fixing item x? 2.7 Where should I look before posting a dumb question? 3.1 How many subscribers are there? 3.2 How many subscribers use machine x? 4.1 Does ClassicCmp have a Web Site? 4.2 How come the Web Site is so ugly? 5.1 Where can I find Classic Computers? 5.2 How much is machine x worth? 5.3 Will 1000's of innocent machines be scrapped if I don't save them? 1.1 What is ClassicCmp? It's a mailing list for the discussion of classic computers. Topics center on collection (just hoarding), restoration, and operation. It is also an appropriate place for stories and reminiscences of classic computers. 1.2 Why is ClassicCmp? Uh, why not? There are lots of people who love these old machines and it seems like a fun idea to get together and talk about them. 1.3 What is a Classic Computer? Any computer that has not been manufactured for 10 years is a classic. This definition is one I made up and it's entirely arbitrary. It seems to work OK, so I've kept it. 1.4 Who runs this thing? That would be me, Bill Whitson. I'm a network administrator at the University of Washington. This is one of my hobbies and I got tired of waiting for someone else to create a list like this. I can be reached at bcw(a)u.washington.edu. 1.5 Do you know you're just duplicating work other people have done. Damn straight. That's what the internet's all about. 2.1 What can I talk about? Anything related to classic computers as defined above. There are many people on this list that really know what they're talking about, so you might want to check facts before you start shooting off messages. 2.2 Can I talk about PCs? Yes. PCs which haven't been manufactured for 10 years. Even then be aware that in many cases you would get a better response posting to PC newsgroups. 2.3 Can I talk about Minis/MainFrames? Yep. Lots of bulky computer folks here. 2.4 Can I post advertisements? Sure. As long as they're related to _classic_ computers. And, of course, use your brain - don't post repeatedly. 2.5 Can I ask people to sell/give me their computers? Sure. But you're not likely to get a very nice response. Mine, for example, would be: Get your own f***ing computer! There are several people on usenet who will vouch for this. 2.6 Can I ask for help fixing item x. Yes. Be aware that it may be difficult to help you fix things if you don't have much knowledge of how computers work or of how to use basic electronics tools (DMM, soldering iron, EPROM burner, etc). 2.7 Where can I look before posting a dumb question? It might be a good idea to take a look at what's available in the Archive section of the ClassicCmp web site (see below). 3.1 How many subscribers are there? Around 200, fluxing daily. 3.2 How many subscribers use machine x? Don't bother asking me. If you really want to know go ahead and post to the list. I really don't know what having a number will do for you... 4.1 Does ClassicCmp have a web site? Yep. http://weber.u.washington.edu/~bcw/ccl.html 4.2 How come the web site is so ugly? How come a PET is so ugly? Who cares as long as it works? 5.1 Where can I find classic computers? The best places seem to be thrift stores and swap meets. These are closely followed by pawn shops and mom and pop computer stores. The holy grails are electronics scrap yards - but they tend to be wary of individual pick-and-choosers. Oh yeah - garage sales! 5.2 How much is machine x worth? Precisely as much as you'll pay for it. Oh, you're selling it? Then , precisely as much as I'll pay for it. 5.3 Will 1000's of innocent machines be scrapped if I don't save them? Yes. This is the impetus behind every collectors tireless and selfless effort. Each machine we fail to save has it's gold parts mercilessly hacked off and sold (just like rhino horns - and look at the rhinos). The remainder is then sent to China to be made into bicycle spokes. Save a computer! Act now! Remind you wife of the rhino and cuter, furrier animals. It might work.

BBSes running on old computers...

by haleyk＠okstate.edu

The IEEE student group that I belong to here at Oklahoma State just ran across an old z-80 based machine called a paraDynamics PRONTO. It seems to be a CP/M machine (we have a box of floppies for the twin 8" drives, and some are marked CP/M 86 and Microsoft Basic, etc.) The guy who was gonna chunk it in the trash said it had a USRobotics 1200 Baud modem and a 20 Meg HD along with 64K or RAM. He threw in a VT and soon as we can jumper around the rusty keyswitch, we hope to get some type of neat program to run on it for the heck of it, we threw around the idea of a BBS (albeit a slow one) possibly written in the BASIC that came with the machine. Has anyone used such a machine? Lets definately keep up the thread on BBSes and if we write it in a 4gl language, maybe a second list can be set up for the distribution of source code. BTW: we also got an IBM 5130.... It boots on a READY prompt, but we have NO CLUE what to do with it! We think the printer could be used as a boat anchor. hasta scott

Sure is nice, I got mine (original PET) from a friend including ALOT of the original documentation, an extra tape drive (Commodore was butchering SANYO tape recorders to begin with), some newsletters (that later turned into popular magazines) and tapes, a splendid addition! I worry about it though, I'm not sure whether it has ROMs or EPROMS, whatever they are they are the original (you know those thin white DIP packages.) >It was, after all, an abused school machine, and the lid wasn't screwed down.

Most of mine are school machines, they sure take a lickin though, the ROM seating problem is common. I have read of people sugessting to replace them with quality drilled sockets.

Unfortunately the PET had a mother board replacement and the jumpers are now wrong, and I'm without docs, so it is not fully functional. Pitty I got a great Space War done like Star Trek game for it. From an ad I still do have, the MTU Visible Mmory Board was deveoped for the KIM-1 and then adapted for the PET, so it's been around for a while.

MOS technologies found out they wern't good RAM manufacturers, the comptible and available chip number you seek is 2114. Which I have found in a Jameco Catalog (415-592-8097) > Even better: Can I simply replace the 6550s with another type of chip and > get more RAM in the system?

Got to hear a demonstration of it some 15 years ago, pretty nice sound! One of these days I might come across one of 'em for my own. Back to RAM, from the next paragraph I would say that you can add via that expansion board. But just in case I'm mistaken, here is something I found in Nick Hampshire's PET Revealed: ... The old 8K machines used 4K bit static RAMs, these were one of two types the 6550 and the 2114. Both these chips are functionally indentical in most respects since they are organised as 1K by 4 bits. The latest versions of the static RAM 8K machines used the 6550.... ... The new 32K and 16K dynamic RAM machines use the 4116 memory chip and the dynamic 8K the 4108. These two RAM chips are pin compatable, with the 4116 having 16K bits of memory and the 4108 8K bits. This is useful since it allows the same circuit board to be used for all sizes of machine.

Atari prob, etc.

by foxnhare＠goldrush.com

Had a huge success at a local thrift store this saturday, much of it is components < 10 years old. But I did find a Power Supply for an Atari Computer (Ihave aquired an 800, 1200xk and 1050 all sans Power Supplies). Soooo.. today I hooked the buggers in one by one: The 800, powered up like a champ! Got the Atari FAQs up and determined I have an 800 with a GITA and the BASIC cartridge is Revision A. The 1200XL is a different matter, Powered up, got the logo, went to diagnostics, sound O.K., Memory looks good, but keyboard... I can get the top row (reset,start,select,option, & help) working but the other keys seem dead. The strange thing is I gboot up BASIC and I press a letter and the computer responds with it's 'click' sound but no key (maybe something in the decoding logic???) Any Atarians got a clue? Since I only have the one power supply I had to power up the 1050 as a standalone the head did a quick back-fourth motion and the activity light stopped so that seems to be a promising sign. Second request: When I get a second supply I gonna kinda need a disk to run on this thing, can anyone help set me up with some essential disks (DOS, utilities, maybe some common games, etc.) I can trade for some fine Commodore Programs and such. (=)) One yard sale find was a batch of Radio Electronics Magazines, dated back in the 80s... Will have to scan through those closely. At first I thought I'd just weed out the ones I wanted and pass on the rest, but I've made that mistake once before.... They will go into storage. Yet another yard sale purchase was a 64 system (I dare not count how many I have), so far so good, the C64 and power supply are fully functional and the keyboard is amazingly clean (i.e. all the keys work, even though It looks like someone tracked mud on the computer). I still have to test the monitor and 1541, but I feel confident they will function. -- >From: Paul E Coad <pcoad(a)crl.com> >Subject: weekend additions >I picked up some good stuff today.

I would've paid that much for that Creative Computing book. >I have a few questions: >Can the Plus/4 run C64 software? BASIC, pretty much so, except if there are POKEs and SYS commands in it it may need some converting, some BASIC may not be easy or possible mainly if there is sprite or sound usage as those chips are VERY different then on the 64. There are some good FTP sites for the Plus/4, just make sure when you download games and demos they are NTSC and not PAL, (PAL graphics are unviewable on an NTSC Plus/4), there are game conversions available (Jim Hehl is probably the most noted for converting programs 64 and Plus/4 european to the American Plus/4 platform). This reminds me I really need to get the adapter pinouts of the Joysticks and the Cassette port on my web page. (whisper.. "if you write it they will browse...") >In the user's manual there is a picture of a 1541 disk drive which looked >black. It was a black and white picture, but the 1541s that I have seen >all match the color scheme of the C64. Has anyone seen a black 1541? Not me, though you can tell Commodore was toying with the idea (on the Plus/4, C-16, MPS-803, DPS-1101, and the 1531 datasette for the Plus/4/16) It could have been the rare Commodore 1551 disk drive. Commodore's attempt at a fast parallel drive. It was to hook into the parallel port of the Plus/4 and delivered a great speed improvement over the 1541 (not too hard of a feat.) I hear it was released in Europe but not in the states. >I now have volumes 1 and 3 of "The Best of Creative Computing", how many >volumes where published? I think they stopped with volume 3, I remember they closed out a bunch of their inventory to schools (which included vols 1-3) at about $100 or so, that was sometime in 1982.

It is the VIC-1541 that I have in my collection. The 1541 is VERY compatible with the Plus/4 and Commodore 16 (thank goodness!) You can adapt a datasette to use on the Plus/4 but Commodore decided to change the pitches at which the data is recorded thus making it impossible to interchange data via tape between other Commodore 8-bits. The format and timing are the same from what I understand.

emulator board help

by jeffh＠eleventh.com

This is likely not really the right place to ask this, but nobody else in other groups has a clue about a 16bit ISA board I have. It is as follows: 16bit ISA board for IBM compatiblle 16mhz MC68020RC16B and MC68881RC16A processors 16 30 pin memory modules soldered directly to the circuit board each module contains 9 41256-120 RAM chips (NEC 8608E621) 1 DB-9 and 1 DB-25 connector (both male) on the rear cover plate Markings: "DSI-780" on the front, and "Rev B Copyright 1986 Definicon" on the rear There is also an empty socket, the same size as the 68020 socket. I aquired this board from a pile of misc. circuit boards that was being tossed out a couple of years ago, and have not been able to find out any information on it. Any info at all would be most helpful. To me, it appears to be some kind of hardware emulator for an Apple or Mac. I know in the late 80's there were a number of Apple II emulator boards for the PC running around, as I recall seeing them for sale in the Radio Shack catalogs of the period. Any help would be greatly appreciated.

Computer Books

by gmast＠polymail.cpunix.calpoly.edu

I'll have to agree on the library as a good source of books. I recently was looking in our library here at school and couldn't find a newer book on PC's. There were quite a few old programming/hardware books from the 70's and a complete set of an old computer magazine from the 60's to the present. Great fun to look at the prices and advertising. And they do sell them. My friend found a book on Volkswagens from the early 60's....$2. Just ask at the circulation desk. They don't have to be in the book sale, just old enough to be of no general value in their eyes. Another good place to look is the Goodwill, thrift sores, etc. Most of us probably already do that but I thought Id mention it. At our local store, customers trash whatever comes neatly in any box. (sad, the disks get thrown around and power supplies disappear too) When they clean up they just pile the manuals on the shelf next to the Danielle Steel novels. I found a complete set of manuals for an Apple III a while back. Tons of Commodore programming guides. Software carts and disks end up in the cassette tape section for some reason. If interested, I could grab whatever I find and sell to interested parties here for cost + shipping. Usually .50 a book + postage. I really don't have the room (or the time) to stockpile books. I just buy what matches the systems I have at the time or what seems rare. Greg

Osborne 1 prices (was: On Generations of People and Computers )

by kaikal＠MICROSOFT.com

Turns out I was too quick to place the blame on an errant journalist. The article, excerpted below (not for profit, and do not forward, etc) actually does say "apple 1" -- it was some bozo on Usenet that made the mistake. The part about the Computer Bowl is correct though. Kai 02490420 60320 THE CUTTING EDGE A Byte of History Techies Taking a Scroll Down Memory Lane Los Angeles Times (LT) - MONDAY August 12, 1996 By: GREG MILLER; TIMES STAFF WRITER Edition: Home Edition Section: Business Page: 1 Pt. D Story Type: Main Story; Infobox Word Count: 1,797 TEXT: The nerds are getting nostalgic. Barely 20 years into the personal computer revolution, techies across the country are growing increasingly sentimental about the machines and programs that changed their lives and ushered in the Information Age. For them, booting up a vintage Commodore PET computer can conjure misty-eyed memories. Toggling the switches of an Altair 8800 is better than gripping the gearshift of a first car. And a shrink-wrapped copy of VisiCalc software beats a mint-condition Mickey Mantle baseball card any day. This is the memorabilia of the PC generation, and after spending much of the last decade or two collecting dust in suburban garages from Silicon Valley to Boston's Route 128, it's starting to make a comeback. Virtual museums of vintage hardware and software are sprouting up all over the Internet's World Wide Web, as are online classified ads placed by collectors desperate to reacquire the technological wonders of their youth. Some rare PCs are fetching much higher prices now than they did when they were brand-new, and even revered institutions such as the Smithsonian are bolstering their computer collections. "The amount of activity that I see is amazing," said Kip Crosby, president of the Computer History Assn. of California in Palo Alto. "People are always asking me: 'Can you find me an Altair? Can you find this or that?' I get 10 to 20 phone calls and e-mails a month, twice as many as a year ago." Most of these early machines and programs, which didn't work very well when they were new, are even more troublesome to maintain now--and have been rendered obsolete by wave after wave of new equipment. But like certain cars or baseball cards, high-tech relics are somehow enhanced by the passage of time. Collectors see them as the symbols of a more colorful computer age populated by legendary personalities who became billionaires--or, in some cases, went bust. "That's why I'm interested in computer history," said Co Ho, 30, an Internet administrator at Fullerton College. "Many people could have made it big, but they fell asleep and ended up having somebody else eating their cake." Ho collects vintage software, especially programs that changed the computing landscape but somehow faltered. One of his favorite pieces is CP/M, an early operating system created by Digital Research. CP/M might have become the operating system had Digital Research's founder, the late Gary Kildall, been more hospitable when IBM came calling to license his software. In a legendary blunder, Kildall and his wife refused to sign IBM's confidentiality agreement, and IBM executives took their business to a then-tiny company known as Microsoft. "CP/M missed the boat because of casual behavior," Ho said. "It's really a sad story." Ho is one of the few people who collect software. More collect hardware, and one of the most sought-after machines is the Altair 8800, introduced by MITS Inc. of Albuquerque in 1975. It didn't have a keyboard or a monitor, only rows of switches on the front of the box. The Altair kit sold for $395 when it was new, but one in good condition today can fetch as much as $1,500 because of the exalted position it holds in computer history. Widely regarded as the first mass-market personal computer, it launched a craze when it appeared on the cover of the January 1975 issue of Popular Electronics. Bill Gates even dropped out of Harvard to develop an early version of the Basic programming language for the Altair. The Altair "established Bill Gates in business," said Gwen Bell, founder of the Computer Museum, a Boston mecca for computer lovers. "One of our prize treasures is the original Basic tape that Bill Gates developed on the Altair." Collectors tend to pass over some of the most popular early machines, such as the original IBM PC and the 1984 Apple Macintosh, because there are just too many of them. Scarcity counts, which helps explain why the most valuable collectible is the Apple I. Introduced by Steven Jobs and Stephen Wozniak in 1976, the Apple I was nothing more than a circuit board. It had no keyboard, no monitor, not even a case. It sold for $666, and only a few hundred were produced. A well-preserved Apple I can fetch as much as $12,000 today, sometimes more. An Apple I signed by Jobs and Wozniak sold for $22,000 at a fund-raiser auction for the Computer Museum several months ago, Bell said. That kind of appreciation has attracted the attention of even non-techie collectors. "I got a call from an investment advisor for a Wall Street banker," Bell said. "He asked: 'Should I get him into collecting old computers? Will they increase in value more than art?' I said, 'I don't know--I'm not a dealer.' " In fact, there aren't any prominent dealers of antique computers, at least not yet. But a few collectors are hoping to change that, including David Greelish, founder of the Historical Computer Society in Jacksonville, Fla. Greelish, a computer repairman, has spent about $2,600 in recent years building a collection of 35 computers, mostly by trolling for bargains on the Internet. He uses search engines such as Yahoo to root out online classified ads for Altairs and other vintage machines, and he keeps an eye on alt.folklore.computers, a newsgroup where history buffs hang out. "Ultimately, I would like to see (the Historical Computer Society) grow and publish magazines and books," he said. "I'd like to start displaying our collection and even restoring computers for sale." Greelish and others said would-be collectors should look for machines that look clean, have all the original equipment and documentation and still run. A number of guidebooks are available, including Stan Veit's "History of the Personal Computer," published by WorldComm in Asheville, N.C., and "A Collector's Guide to Personal Computers and Pocket Calculators," published by Krause Publications in Iola, Wis. Experts urge caution, however. There's no guarantee that old computers will grow in value, and they are very difficult to maintain. "If you've never opened up your computer and looked inside, this is probably not the collectible for you," Bell said. Instead, experts say, this is a hobby better left to people who were enthralled by the recent PBS documentary "Triumph of the Nerds," people who still have a soft spot for monochrome terminals, "Chiclet" keyboards and the odd shapes of the early machines. But even among techies, there are plenty of people who scoff at this new fad, including Kim Nelson, service manager at ACP Superstore in Santa Ana. Founded 20 years ago, ACP is one of the oldest computer stores in Southern California, holds swap meets that attract legions of collectors, and might be one of the region's best unofficial museums. The store's top shelves are crammed with artifacts of computer history, although Nelson calls it junk. "Isn't it amazing that we have computer folklore now," he said, walking with a reporter along rows of vintage Commodores, Imsais and Tandys. "That's kind of sad when you think about it. Seems to me there are things that are a lot more important." But as he uttered those words, service technician John Krill walked by and surveyed the line of creaky machines. Almost against his will, Nelson was sucked into an episode of technology reverie. "Look at that Kaypro," Krill said. "That company grew so fast they were warehousing their inventory in tents." "Weren't they the ones that had the fire too?" asked Nelson, perking up just a bit and eager to demonstrate his techno-trivia prowess. The conversation drifted from machine to machine. "When I was in college, I would just leave my Osborne up in the library," Krill said with a laugh, recalling the immobility of the first portable computer. "The damned thing weighed 27 pounds. I didn't want to lug it around." Fifteen minutes passed before the two realized that their walk down memory lane might have strained the attention span of their guest. "That's enough, John," Nelson finally said with an embarrassed grin. "You're boring him."

Only a few hundred were produced. Mark-8: A kit computer that was the subject of the first magazine article describing how to build a computer. The article appeared in Radio Electronics Magazine in 1974. Scelbi: Predated the Altair and was the first computer based on a microprocessor advertised for sale. Only a small number was made. Altair 8800: Programmed by switches, the Altair 8800 had no keyboard, no monitor and just 256 bytes of memory. But it is widely regarded as the first mass-market personal computer. The Altair, based on an Intel processor, started a craze when it appeared on the cover of Popular Electronics magazine in January 1975. Imsai 8080: Modeled on the Altair, the Imsai had several technological advances and a more polished look. Had no keyboard or monitor but was briefly the fastest-selling personal computer. Apple II: This is the machine that launched the company--and the personal computer industry. Apple II computers came with a keyboard, monitor and two disk drives. Most important, they ran VisiCalc, the original spreadsheet program that was the personal computer's "killer application." Osborne I: Considered the first portable computer, even though it weighed about 30 pounds and was the size of a suitcase. It had a 5-inch screen, two floppy disk drives and 64K of RAM.

Osborne 1 prices (was: On Generations of People and Computers )

by kaikal＠MICROSOFT.com

| I'm just curious - have any of you (with the possible exception of the | apple I) ever seen anyone selling these models at these prices much less | purchased one for so much? Do any of these warrant such a price for | you? $400 for an Apple II? $300 for an Osborne? I bought an Apple II+ | with 3 Disk IIs, color monitor, and box of accessories for $50 - | in 1988! Well... here are my thoughts: > > Here are some of the PCs attracting the attention of nostalgic > > techies: > > > > Model: Apple I > > Current value: $10,000-$12,000 > Unverified, the only high-dollar example I know of is the Computer Bowl auction unit. I know someone who actually has two Apple I's, and since I actually have more than one Altair, I'm trying to talk him into our becoming about the only two people with one of each. Wish me luck! > > Model: Mark-8 > > Current value: $3,500-$4,000 > Highly dubious, since I have never seen, and probably will never see, one of these for sale. Heck, it wasn't even a genuine production machine, it was mostly just instructions on how to build one from scratch. Who knows what it would even look like? Every one was different. Since most if not all of the period's TTL stuff is still available, you could build something today and call it a Mark 8. Most people looking for an Altair would say "A Mark what?" > > Model: Scelbi 8H > > Current value: $1,200-$1,500 > Why this should be lower priced than the Mark-8 considering that it came out earlier ('73 vs. '74, according to Byte), is beyond me. The same comment as for the Mark-8 applies. The Mark-8 and Scelbi are sort of like the guy who almost got credit for inventing the telephone. It's doubtful that history will ever be rewritten sufficiently for there to be a significant interest in these machines. Not that _I_ wouldn't buy one, mind you... not for these dollars of course, but for a goodly sum. > > > Model: Altair 8800 > > Current value: $1,200-$1,500 > This might actually be a bit low, considering the amount of 'Altair Fever' around today. You should see the number of 'Altair Wanted' posts on various sections of Usenet. Geez! Is it worth it? I'd say, sure it is! My dad's '57 fuelie 'Vette is just as primitive by today's standards, but just like the Altair, it looks fantastic and it's a piece of history. It darn well deserves its more-than-a-new-one price tag. Of course, my dad restored it himself, since he always wanted one when he was a kid... sure sounds like his son's relationship with antique computers! > > > Model: Imsai 8080 > > Current value: $400-$600 > This is accurate, perhaps a bit low as well. They're pretty rare (one less in circulation as of this weekend - thanks Tim!) > > > Model: Apple II > > Current value: $200-$400 > Well, we all know this is a joke. The highest price I've seen for a plain // is about $60. I'd probably pay $200+ for a pristine one in the original box with manuals, etc. but I don't think that's what they mean. Of course, I haven't been able to find a nice one myself, so... > > Model: Osborne I > > Current value: $200-$300 > Tough call. It's reasonably, but certainly not vanishingly, rare (I've owned three at various times) and I'm sure there are folks in the world that would pay this, but I generally see them going for around $100, and more like $15 at swap meets or thrift stores.

I have an Atari 2600 carthridge question: I bought a couple at a swap meet that don't "boot" up. When I turn the unit on the screen either is black or has random vertical color bars on the screen. They are both Activision games. Any suggestions? I tried opening them but can't without ruining the label. I guess a working cart is worth more than a ruined label, but I'm hoping there's a better way if there is some way to fix them. Hey, let's have a contest. Let's see who can score the best lot of classic computers this weekend. We can score each other based on the type and age of the computers/software/accessories we got, then tally up the points and whoever has the highest score gets a pat on the back. The point to such a silly game is that it will promote the preservation of old computers. It will get us out there finding these lost souls and keeping them safe for future generations. And believe me, there's nothing more gratifying then a good weekend out hunting for good old computers!

Osborne 1 prices (was: On Generations of People and Computers)

by kaikal＠MICROSOFT.com

| Aha! You have a point! Anyone remember the time when Osborne-1s were | supposedly rare and were priced at around $1,000-$10,000? Ha ha. Nice joke. This stems from a California reporter who got confused when talking to collectors and printed in the newspaper that an Osborne 1 sold for over $10,000. The collectors were actually talking about an Apple I, not an Osborne 1 (an easy confusion for a layman to make). An Apple I sold at the Computer Bowl charity auction (filled with billionaires) for that price, but even that doesn't mean that an Apple I is _worth_ $10K, just that someone made a nice charity donation in connection with one.

Regular Posting: FAQ

by bill＠booster.bothell.washington.edu

============================================================================= ClassicCmp - The Classic Computers Discussion List FAQ (Frequently Asked Questions) v1.2 Last Update: 4/16/97 ----------------------------------------------------------------------------- This FAQ is written with the primary purpose of making readily available answers to the more common questions appearing on ClassicCmp. It is Maintained by Bill Whitson <bill(a)booster.u.washington.edu>. The infor- mation in this document has been gathered from a variety of sources but, in general, the members of ClassicCmp should be credited for all contain- ed herein. I have, of course, endeavored to be as accurate as is possible and often failed ;). If you have questions, comments, or corrections (always welcome) please contact me at the address above. ----------------------------------------------------------------------------- This FAQ has jumped 2 updates because I've been lazy about posting it. Part 5.4 is new Sections 6-9 are new. ----------------------------------------------------------------------------- About ClassicCmp ----------------------------------------------------------------------------- 1. About the List ----------------- 1.1 What is ClassicCmp? 1.2 Why is ClassicCmp? 1.3 What's a Classic Computer? 1.4 Who runs this thing? 1.5 Don't you know you're duplicating what others have done? 2. Protocol and Etiquette ------------------------- 2.1 What can I talk about? 2.2 Can I talk about PCs? 2.3 Can I talk about Mini/MainFrames? 2.4 Can I post advertisements? 2.5 Can I ask people to give me their computers? 2.6 Can I ask for help fixing item x? 2.7 Where should I look before posting a dumb question? 3.

It's a mailing list for the discussion of classic computers. Topics center on collection (just hoarding), restoration, and operation. It is also an appropriate place for stories and reminiscences of classic computers. 1.2 Why is ClassicCmp? Uh, why not? There are lots of people who love these old machines and it seems like a fun idea to get together and talk about them. 1.3 What is a Classic Computer? Any computer that has not been manufactured for 10 years is a classic. This definition is one I made up and it's entirely arbitrary. It seems to work OK, so I've kept it. 1.4 Who runs this thing? That would be me, Bill Whitson. I run this thing when I'm not busy being a network admin at the University of Washington, SCUBA diving, playing drums in punk rock bands, or drinking heavily. Oh yeah, I'm a 22 year old, unmarried, childless, white, male living in the state of Washington in the US. People ask you the strangest things when you run a listproc... 1.5 Do you know you're just duplicating work other people have done. Damn straight. That's what the internet's all about. OK, guess I have to update this too - I get a "reinventing the wheel" e-mail at least once a week. If you show me another group of computer collectors that claims a membership as large as this one I'll show you a group that must be very hard to find. Obviously there are other groups of collectors and I'm cheering them on - I don't see a problem with duplicating and reduplicating lore that's quickly disappearing anyway. 2.1 What can I talk about? Anything related to classic computers as defined above. There are many people on this list that really know what they're talking about, so you might want to check facts before you start shooting off messages (if you're easily embarrassed). 2.2 Can I talk about PCs? Yes. PCs which haven't been manufactured for 10 years. Even then be aware that in many cases you would get a better response posting to PC newsgroups. 2.3 Can I talk about Minis/MainFrames? There has apparently been some misconception that this is a list for micros only. You'll note I said "misconception". 2.4 Can I post advertisements? Sure. As long as they're related to _classic_ computers. And, of course, use your brain - don't spam. 2.5 Can I ask people to sell/give me their computers? Sure. But you're not likely to get a very nice response. Mine, for example, would be: Get your own f***ing computer! There are several people on usenet who will vouch for this. See section 5 for info on how to find your- self a computer. 2.6 Can I ask for help fixing item x. Yes. Be aware that it may be difficult to help you fix things if you don't have much knowledge of how computers work or of how to use basic electronics tools (DMM, soldering iron, EPROM burner, etc). I'm no whiz with this stuff and the little knowledge I have has come from asking questions and then buying books to find out what "Simple... Just check the voltage on the caps in the PS to make sure one of them isn't flaking out!" exactly means. 2.7 Where can I look before posting a dumb question? It might be a good idea to take a look at what's available in the Archive section of the ClassicCmp web site (see below). 3.1 How many subscribers are there? Around 230, fluxing daily. 3.2 How many subscribers use machine x? Don't bother asking me. If you really want to know go ahead and post to the list. I really don't know what having a number will do for you... 4.1 Does ClassicCmp have a web site? Yep. http://weber.u.washington.edu/~bcw/ccl.html 4.2 How come the web site is so ugly? How come a PET is so ugly? Who cares as long as it works? 5.1 Where can I find classic computers? The best places seem to be thrift stores and swap meets. These are closely followed by pawn shops and mom and pop computer stores. The holy grails are electronics scrap yards - but they tend to be wary of individual pick-and-choosers. Oh yeah - garage sales! 5.2 How much is machine x worth? Precisely as much as you'll pay for it. Oh, you're selling it? Then, precisely as much as I'll pay for it. Seriously, no one prices these any more. I have an old Computer Blue Book that lists many classic computers but the prices are just ridiculous. Some machines (Apple Lisa's, old old Mini's, and unreleased prototypes) are starting down the road toward their original selling prices. 5.3 Will 1000's of innocent machines be scrapped if I don't save them? Yes. This is the impetus behind every collector's tireless and selfless effort. Each machine we fail to save has it's gold parts mercilessly hacked off and sold (just like rhino horns - and look at the rhinos). The remainder is then sent to China to be made into bicycle spokes (you probably think I'm joking). Save a computer! Act now! Remind your wife of the rhino and cuter, furrier animals. It might work. In all seriousness - there are a large (and growing) number of so called "computer and electronics 'recyclers'" who take usable computers and recycle them into "reusable scrap". Small amounts of gold, silver, and platinum are extracted and the remainder of the material is generally just marketed to less wasteful countries. 5.4 I just picked up a new machine. What should I do? Don't power it up yet! All of the following should probably be done before that power switch gets flipped. Open the case - clean and visually inspect components. You're looking for traces of smoke, water, corrosion, loose screws, blown caps and resistors, etc. You can avoid a number of problems just by taking a peek inside. If you have the tools (and the machine is sufficiently rare) pull and dump backups of all EPROMs, ROMs, and PALs. Disconnect the power supply from the rest of the computer and start it up on a "dummy load". A six volt headlight bulb has been recommended as a convenient load. These should be available >from any decent Volkswagen shop. Hopefully this will prevent frying the rest of the machine with a flaky power supply. You may want to check the voltage output before you do this as it could be no where near the 5V average in micros. Even if you don't want to connect a load it's still probably a good idea to power it up separately from the computer for the first time. If you have a really rare beast it may be worth powering up some of the key capacitors out of circuit just to get them warmed up. Now you can power it up. Assuming it works, take a blank disk, format it, write some data to it, and read it back before using your precious software with it, as a bad disk drive could really ruin your day. 6.1 What's the best way to clean these dingy tan boxes? Cases: It seems best to start gently with such old equipment. Try soaking in a little water and dish soap and then scrubbing. This takes care of most jobs. For removing stickers try mineral oil or Goo-Gone (available at most hardware stores - in the US at least). If those don't work, acetone can be good but, if overused, can do more harm. For removing marker, almost any solvent is good (alcohol, naptha, etc) but will definitely discolor or dissolve plastic if not carefully applied. Lava soap is also good for removing marker but can smooth off textured plastic. For removing sun or tobacco discoloring a product called Purple Stuff available from auto parts stores (again, in the US at least) seems to do the job almost effortlessly. Connectors: For edge connectors a plain pink eraser seems good for removing corrosion. Make sure to wipe the connectors with a clean cloth after erasing on them though. There are a large number chemicals on the market that "magically" remove corrosion from comp- onents but I'm not anxious to promote any of them. For pin style connectors a toothbrush and some softscrub or other mildly abrasive cleaner do wonders. Keyboards: I find a cycle through the dishwasher does a really nice job on keyboards. Just be sure they're completely dry before you put any power to them. 7.1 What's a hard sectored disk? What's a soft sectored disk? We'll start with soft-sector since they're simpler to explain. On a soft-sector floppy disk the information that marks where a sector begins and ends is written to the disk by the computer (part of the formatting process). This means that various computers can use the same floppy disk types because the format of the disk is control- led by the operating system. Hard sector disks use a system of perforations in the media to mark the beginnings and ends of sectors. This means that computers which used hard sectored disks required the exact disk type they specified rather than a generic soft-sector floppy. A number of differently sectored disks were available - at least 10, 13, and 16 sector formats. 8 inch and 5.25 inch disks commonly used hard sectoring. To my knowledge it was never used with 3.5 inch disks. 7.2 What's SS/SD, DS/DD, DS/QD, DS/HD, etc. These all refer to the number of useable sides on a disk and it's density (how "efficiently" the magnetic bits are pushed together). SS/SD is a Single Sided - Single Density disk, the earliest available type I believe. The storage afforded by a single density disk was very small compared to today's standards. Single Sided disks were popular because they were cheaper than DS and could be easily modified with a hole punch into double sided disks. SD was followed by Double Density which, amazingly, doubled the amount of storage space. Double Density was followed by the extremely short-lived Quad Density which doubled a DD disk. QD was short lived because High Density was right on it's heels and nearly doubled disk capacity again. DS/HD was as sophisticated as 5.25" disks became. 3.5" disks have progressed as far as DS/EHD double-sided / extra-high density. 7.3 Can these formats be interchanged? Well, that may depend on what computer you are using, but in general the following substitutions may be made: Desired Format Substitute --------------------------------------------------- Single Density Double Density Double Density none reliably Quad Density High Density High Density none Other substitutions may be made, but due to physical differences in how the disks are made they are generally unreliable. It can almost be guaranteed that data written to a proper density disk of poor quality will last longer than data written to a good quality disk of the wrong density. 7.4 What disk sizes are there? Physically? There are 8 inch, 5.25 inch, and 3.5 inch as "standard" disks. There are also some unique and/or short-lived sizes such as 3 inch disks used by Amstrad and 2 inch disks which were pioneered for use in laptops and then quickly forgotten. 7.5 How do I take care of old media? Step one is Back It Up! After that, make sure it's kept in a clean, dry, temperature-controlled environment (I keep mine in a broken freezer). With disks it seems important to keep them standing on end rather than lying flat - the same goes for cassette tapes. I like to exercise disks and tapes at least once every six months although I have no real evidence that this has any positive effect. I have modified an old C64 floppy drive to simply spin when a disk is inserted and send large stacks of disks through it on a regular basis just to make sure they're not starting to stick up internally. An exciting and somewhat recent development is that availability of classic computer emulators that can make disk images of old media on PC's and Macs. This seems to be a very good way to backup disks since they will eventually go bad no matter how well we take care of them. The official line seems to be that floppy disks have a shelf-life of approximately 10 years. With proper care many are lasting a lot longer. 8.1 Do EPROM's go bad? Definitely. They apparently are considered to reliably contain data for (on the outside edge) 15 years. This amount can be considerably reduced if, for example, the sticker over the window has dried out and fallen off. Luckily EPROMs were not used too extensively but they're out there. An EPROM writer/reader is a relatively cheap investment and an easy fix. Even if an EPROM has "forgotten" it's data it is still fine for being "re-educated". 8.2 How about ROMs and other chips? Things wear out. It's likely that even components which have not been fried by catastrophic failure will simply start to die someday. ROMs can be dumped to a file and re-written if they die. Other custom chips which are all too common in micros will be far more difficult to replace. The best advice is to stockpile these chips when you can - but someday even unused chips will probably start to turn up bad. In this case the best defense is to stockpile information in the hope of being able to modify an existing component to meet your needs. 8.3 How about capacitors? This seems to be another large concern, but rather than being an unreplaceable component a capacitor will take your unreplaceable components with it when it goes. It's a good idea to check out all the caps in a system if you haven't fired it up in a while. Caps go bad with time (even tantalum caps, apparently - although they are more reliable) and should be replaced if they are suspect. It's unlikely that it will be impossible to find a replacement capacitor as they are much more standard electronic components. 8.4 Anything else? Documentation: If there's anything which is entirely unreplaceable its the docs for uncommon equipment. Once they're gone, they're gone. I regularly pick up docs I find for equipment I don't have just because I may someday. Paper will, of course. go bad over time but it will be obvious and they will be easily duplicated. Hard Disks: ST-251s, ST-502s, MFM, RLL... old hard disks are going to go bad. Then they'll be gone. Theoretically, I suppose it's possible to crack a hard drive and replace a dead bearing, realign, relaminate, etc... but I've never heard of anyone doing these things in their base- ment. Perhaps in another 5 or 10 years many of us will be experts at this. 8.5 So, how do I back up all this stuff like you suggest? This answer will undoubtedly get longer as I learn more. The best ways seem to be to dump the particular ROM (or whatever) using the approp- riate equipment to a floppy disk (which most of this equipment allows).

Apple Lisa Power Supply...

by kevan＠motiv.co.uk

Hi, While I have the attention of Lisa owners with the other thread I thought I may make this request... I have owned a Lisa 2 for a number of years now, but unfortunately it has a mostly broken power supply unit. Over this time I seem to have got close to finding spares or schematics more times than I care to remember, only to be let down at the last minute. (Sorry, sob story over now.) It is a complex beast and I don't have the technical know how to fix the problem, but I do have friends, who are skilled electronic engineers, who say they can do it with the schematics. Has anybody got the schematics for a Lisa 2 power supply? Failing this has anybody got a working spare they are willing to part with? Or do you know of a cheap source of them? Many thanks... -- Kevan Old Computer Collector: <URL:http://staff.motiv.co.uk/~kevan/>

Atari 2600

by alexios＠vennea.demon.co.uk

I remembered a message here about pricing and video games yesterday. Someone had an Atari 2600 (the new, revamped, black type) at the car boot sale in Edinburgh yesterday. He explained to me that this was a "games computer" with around 8 carts (<sarcasm>lemmesee, Pacman, Ms. Pacman, Pole Position, etc. -- ooh, rare</sarcasm>). The price: 20.00 UKP (around $30?). Surely, these people are joking. I didn't even want to haggle for a new VCS. Now, if it was the *OLD* type, I might have been interested (I don't normally collect this stuff, but the old VCS has sentimental value -- I played my first game of Space Invaders on one). Unfortunately, at another flea market, another time and another country (and anyway, the wench is dead), an original VCS was going for around $100, with extremely common carts selling for as much as $25. Amazing. Almost as expensive as the thing when it first came out. :-) My theory for this is that game machines haven't changed all that much in the last 20 years: still a box, still take carts (or CD-ROMs nowadays), still have joysticks. What the heck, it must be worth something, right? Whereas computers have changed so dramatically that your average car boot sale joe will sell an old `computer keyboard' (probably a ZX-80) for peanuts since it doesn't appear to have a monitor or a CD-ROM or Winblows installed. --------------------------- ,o88,o888o,,o888o. ------------------------------- Alexios Chouchoulas '88 ,88' ,88' alexios(a)vennea.demon.co.uk The Unpronouncable One ,o88oooo88ooooo88oo, axc(a)dcs.ed.ac.uk

FAQ

by dcoward＠pressstart.com

I was just reading the FAQ and thought that I should add my two cents. 6.1 What's the best way to clean these dingy tan boxes? Paper items: About a year ago, I found an Osborne Starter Kit in a thrift store. This is a ring bound manual and some audio cassettes to get a new user started, packaged in a flat cardboard box, the kind with a glossy surface. Well the box had been wrapped many times with that inch and a half clear packaging tape to prevent it from being opened. I knew that if I tried to remove the tape that I would remove most of the surface of the box too. Then I had an idea. I removed the manual and the tapes from the box by cutting the tape around the edge of the box. And then I put the box in the freezer for a few hours until it was nice and cold. I still had to be careful removing the tape but the tape didn't stick to the box as well as it did when it was warm. And it didn't leave any glue behind. The one that I havn't licked yet is how to remove crayon price marking from a paper diskette label or a book page without it smearing or bleeding into the paper. 7.4 What disk sizes are there? A floppy diskette is 8" in width. A mini floppy diskette is 5.25" in width. A micro floppy diskette is 3.5" in width. And computers like the Amstrad CPC6128 and the Sinclair ZX Spectrum+3 use a compact floppy diskette which is 3.15" or 8 cm in width. I also have diskettes made by Nintendo (the word Nintendo is embossed in the plastic) for the Nintendo Family Computer. I don't know what they're called and I haven't measured one yet, but as I remember they are just a little smaller than a micro floppy. ---------------------------------- My computer collection up on the web still needs a lot of work, but I'm looking for suggestions about: - the way it's laid out - are the pictures too big to download quickly - is there incorrect information If you can help me out, my collection is located at www.best.com/~dcoward/museum Thanks ---------------------------------- >>Is everyone else in their 20's and 30's?

PET stuff

by ds_spenc＠alcor.concordia.ca

Does anyone out there know much about the old PET 2001 machines? I received a PET a couple of years ago, in which all of the 6550 SRAMs were fried. I replaced them with the chips from another PET 2001 (one with the miniature keyboard, from 1977) and the system worked fine. Does anyone know how all of the memory chips could've been killed? I tried them in various patterns in the sockets, and it does seem as if all 16 of them are fried. Anyway, is it still possible to get 6550s anywhere? And if not, is there a replacement that could be used? Even better: Can I simply replace the 6550s with another type of chip and get more RAM in the system? Most of my software works in 8K, but I do have some music files that require more. (I have one of those external music boards that plugs into the cassette2 and user ports, that delivers four voices.) Now, another question. With that same PET, came an expansion board of some kind. Its like a daughterboard, physically mounted on posts above the motherboard, but connected via the memory expansion connector on the side. It appears (yes) to be a memory board, with 16 RAM chips on it. At least, they look like they could be RAM chips, judging by the traces on the board. However, I've never seen RAM chips with gold contacts and gold plates on their backs before, as six of these chips have, so I'm wondering if this could be more than just a memory board. The board is dead, BTW. The PET won't operate with the board plugged in. It just comes up with a screenful of garbage characters. The board plugs directly into the PETs power supply, and then a cable leads from it to the PET motherboard's power connector. There are three large 470uF capacitors and two things that I guess are voltage regulators (I don't know much about electronics :) ), so I'm guessing that this board has its own refresh circuitry on it and it uses DRAM, but that could be totally wrong. :) Both connectors on the cable that leads from the expansion board to the motherboard are noticeably burnt. In both cases, the burn marks surround the pin that connects to the black wire. The only identifying mark on the board is the text: R 3014 rev. C COPYRIGHT 1978 R.C.Factor Does anyone have any better guesses than me as to its function? (Can the edge connector on the side of the PET be used for anything other than RAM expansion?)

The *first* micro floppy was 3" in width. Yes, you heard me correctly. Amdek designed and built a SSDD 3" floppy drive around 1983-84 (or so... I'll have to look) that used it's own style of media (and it was flippy, unlike the 3.5" of today) and they interfaced it to and marketed it for two computers that I know of: The Radio Shack (Tandy) Color Computer, and The Atari 800. So far I've seen 2 Atari units for sale on the forsale newsgroups in the last 9 months or so, and altho I've never seen the CoCo version (on sale or anything) I have a color magazine ad advertising the system that I could scan in if I ever find the time... ================ Also, in the grand naming scheme above, just *what* would you call a 2" floppy? Yessireebob, a 2" floppy! I *own* one of these drives... they were used in the Zenith MiniSport 8088-based IBM/clone laptop. Cute little rascals... someday I'll take a pic or two and scan 'em in... Specs: 2" floppy, 80 Track, DSDD 720K formatted storage capacity. (I don't know the TPI or anything... may look into that if possible...)

Hard/Soft sectoring

On Wed, 16 Apr 1997 22:23:30 -0400, this arrived on the list from the esteemed Mr. Allen Underdown: > In the olden days of magnetic floppy media, there was a sector hole > FOR EVERY SECTOR located around the hub of the floppy. All very well and good, but there's that one extra you forgot about. ;-) Yes, hard-sectored disks _do_ have a hole to denote the beginning of each sector, but to indicate the beginning of a _track_ they use two adjacent holes. In soft-sectored disks, the single hole serves to signal the beginning-of-track; the individual sectors are defined via headers recorded during the format operation. > God I love reading this list!

Here are a few extra things I need to part with to make space: 1) TI-99/4A, silver/black, with power supply. No RF modulator. works great....$15 + shipping 2) Amiga 1000, main unit only..no keyboard. Bad floppy and missing the cover which goes over the RAM expansion on the front of the unit. Also is missing the 68000 CPU. This system is said to have worked ok, but I bought it for it's keyboard and it is just sitting here. I really hate to trash it, so anyone who is interested can have it for the cost of the shipping. An interesting thing about it is that it, like all A1000's, has the underside of the upper casing 'signed' by all it's designers, including Jay Miner.

Supra sold a 5-1/4" floppy drive for the Atari ST that would hold 10meg on a disk, though the drive used a laser to track the head position, and the disks were special and had special markings on them to allow the laser to track where it was on the disk. I had one of these drives at one point, but could never locate any disks for it.

The only PC Jr. keyboard I've seen in use, and I have one here though no PC Jr., is the one that has the two IR leds on the rear, an RJ-11 type jack, and a space for 4 'AA' batteries. How many different keyboard types were there for the Jr.?

Oh come on, guys. I'm not _that_ old :-) (36). One of the reasons that I cherish the minicomputer architectures is, admittedly, nostalgia, but the other reasons include the fact that they're very servicable (frequently with off-the-shelf components) and they provide a wonder tactile sense of the essence of computing. Few things compare to hand-assembling programs, entering them in binary via a front panel, and having them work. Also, the average minicomputer is simple enough to understand its' inner workings at a gate level; this makes minis admirable teaching tools. > I started my computing on my older brothers ZX80, I was 13 at the > time. Thus I was brought up on the home computer boom of the early > eighties. I was a bit of a "late bloomer" when it comes to computing. I was always interested in the machines, all the way from early childhood, and was lucky enough to have relatives with contacts at MIT and Harvard. I got to see some wonderful stuff then (even played Space- war on Harvard's PDP-1!) but never got to do any programming until my second year of secondary school in the late '70s. The first machine I programmed on was the Nova 840 I have in my collection now. The machine I "cut teeth" on in a hardware sense was an Inter- data Model 3, in my third year of ss. Although I bought a VIC-20 (for the princely sum of (US)$300) in 1980 (?), I never really "took to" the micro- architectures (it might also have been that they were so _slow_ compared to the PDP- 10s I was working on at the time). I think I still have the VIC around someplace.

Well, today was a rather good day out at the swap meet, my first excursion in a couple years. It started out slow. The first thing I found was one lowly Atari 2600 PacMan cart sitting amidst some guy's junk. For some reason I thought I would buy it (?) thinking maybe I didn't already have PacMan (whatever) and it went like this: Me: How about a quarter? Him: 1 dollar. Me: A quarter? Him: 1 dollar. Me: How about 50 cents? Him: ok. Anyway, it got way better. Walking along I found a beautiful little TimexSinclair 1000! At least I'm am darned sure it is, because the label is missing on the top but the bottom has a stamp which has "CEC8E4TS1000R1" in it. There is also a sticker with a serial number and "Model M330" on it. Anyway, I've never actually seen one, but have been looking for one for years! And finally its mine! MINE! Haven't tested it yet but I'm sure it works. Its in good condition. Could someone who has one describe theirs so I can figure out exactly what I have? I know there were different varieties of the TS1000. Mine has an Ear and Mic jack on the side. What the hell are those for? Oh, duh, just figured it out...data recorder. Never mind. You know how hard it is to find a 9V DC power source with a 1/8" headphone jack? I looked all over the meet for one, finally found one but the seller wanted three bucks for it so I passed. I can't encourage that kind of larceny :) So continuing on I found some more Atari 2600 carts I didn't have, and then I found an original IBM PC/XT. The guy wanted $50 but I promptly talked him down to $7. What a steal. Haven't tested it yet but it "looks" like it will work :) Now I want the Original IBM PC and a PC Jr. The funny thing is, I paid more for 9 Atari 2600 games ($11 in one case) than an entire PC. So moving forward, I found someone selling a Macintosh 512K. Cool, I'd been wanting to add a classic Mac to my collection for some time. But this one was missing the keyboard and mouse. They only wanted $20 for it. I tried talking them down but they didn't want to move. Later I found someone selling a complete Mac+. Now this one I know was hot. At first they wanted $50 but I talked them down to $15 (I used the "It's all the money I have right now" ruse, except in this case it was true). I really wanted to get the other Mac, because it was closer to the original Macintosh, but this one was more complete, so I got it instead. Now, I don't want to disparage the fine folks of Oakland, California, but as I said before, I'm most positive this system was hot. They were too willing to dump off a perfectly good Macintosh (at least I think its perfectly good, haven't tested it yet) for too little money. Later on when I was going through the software I got with it I found some BMUG disks (BMUG = BayArea Macintosh User's Group). So I'll be contacting BMUG to see if any of their members "lost" a macintosh within the last couple months, and if I find a match I'll sell it back to them for what I paid. (I'm such a nice guy, eh!?) Throughout the day I saw a LOT of Nintendo consoles, carthridges and accessories (not classic enough yet). I'm sure in 5-10 years when I inevitably start collecting Nintendo crap I'll be wishing I had picked up a lot of this stuff. Oh well, maybe when I have enough money to buy all the truly classic stuff I want and THEN some cash left over for the common tripe, I'll start collecting nintendo. So anyway, at the end of the day I ended up with an IBM PC/XT (original), a MacintoshPlus, a TimexSinclair 1000 (yeah!) and about 25 more atari 2600 carts, plus an intellivision cart and a TI/994a cart. Total bill: $45. Not bad. And I'm still under my budget of $100 per month for classic computer collecting (I just implemented that budget, but I think it may be too high. I tend to get carried away when collecting old computer stuff and, if left unchecked, would buy everything I came across. As it is I just may go back for that Mac512K.) Now I just need to keep my new booty hidden from my fiance. If I can offer any tip to would-be flea market bargain hunters: haggle. Start way low and work up. Some people don't even know what they're selling, and think just because it's a computer (computer = high tech) it must be worth big bucks. You have to slap them around a bit until they come to their senses. No common system console (ie. Vic20s, Atari 2600s, etc) should go for more than $10 ($15 at the VERY most). No game carthridge should go for more than $.50 (IMO, unless you REALLY want it, then NO more than $2.00 each). What do you all think?

Hewlett-Packard HP125 Keyboards

by dcobley＠island.net

Hi all. I'm pleased to report that the Xerox 16/8 system I offered for adoption here, has started its lengthy journey to it's new home in North Carolina, and the Kaypro Service manual is on its way to Oregon. Now its my turn to ask for help. Some time ago, at our local Thrift store, I bought two Hewlett-Packard HP125 Display units. They contain the monitor and CPU for these CP/M units and I have a good collection of suitable peripheral drive units. I only paid $2:50 each for the Display units. And they seem to work OK but I really can't be sure until I get keyboards. I also have a set of boot disks for them. But I have no keyboards. I understand the same keyboard was used with the H-P 26xx series of Terminals. Does anyone have one or two suitable keyboards they'd be willing to sell to me? My e-mail address is listed below. Thanks and cheers, David Cobley. Fidonet on the ADAM, CP/M Tech and Hewlett-Packard Echoes. Internet-dcobley(a)island.net, or, davidc(a)macn.bc.ca

Sam, The transformer with my TS-1000 shows an input (to the computer) of 9.75V DC. Both my TS-1000 and Sinclair ZX-81 seem to be picky about TV's and the shielding of the cable. As for identifying marks, from your previous post, the only thing my TS-1000 has on it is the FCC ID# CEC8E4TS1000R1. Otherwise, there's no mention of the number you mentioned...just the sticker on the top 'Timex-Sinclair 1000'. The box and such doesn't give any indications to other identifiers either. Hope this is of some help.
