If your e-mail bounces, post your request publicly. If you want to add to your count, let me know. I will be sending the final total to Mike on Friday, so I will take requests up until sometime Friday when I fire off an e-mail to him. At that point I will try to cut a deal. I'm hoping for 100. Nobody will pay more than $10 per. If we get to 100 it should go down to $9 per. Remember...manuals, power supplies, ROM chips, custom RAM expander tray, some carrying cases. Features thermal printer, FORTH-like language in ROM, QWERTY keyboard. If you don't know what the hell I'm talking about, ask for details.

IBM PC Radio 9075

by sinasohn＠crl.com

This weekend I picked up two IBM PC Radio laptops (numbered #9075). Anyone know anything about them? They came with no PS and the batteries are (of course) dead. They're nifty little machines, with a built-in ~adding-machine-sized printer, a connection for an antenna (at least, that's what it looks like) and a PCMCIA-ish slot. Any info would be greatly appreciated, as well as leads on finding a power supply or two. Thanks! --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)crl.com that none but madmen know."

Apple & Commodore Stuff on Auction

by gmast＠polymail.cpunix.calpoly.edu

Hello again. Time for the list of stuff. I have listed some items on a different auction than eBay AuctionWeb this time. It's a new auction so it's faster to search (less listings) and they do have a vintage computer category and a Non-PC/Mac software category. I'm still trying to reduce the pile (and get a little money for tuition next month) so everything sells for whatever the high bid is. Most of the power supplies/boards have been going for about $5 so far with a few exceptions. Remember to figure shipping in to what it's worth to you, I'm in Central CA. AuctionWeb: Mac II Logic Bd - NEW! Sealed From Factory! Bidding starts at: $5.00 Auction ends on: 07/13/97, 16:54:10 PDT http://www2.ebay.com/aw/itemfast.cgi?item=dcv57812 Apple IIc Power Supply NEW!

Amiga32? What's this?

It's a > nice-looking unit, with a CD-ROM on top. Anyone know what it is? > It's called a CD32. It's basically an Amiga 600 minus keyboard, in a one-piece unit similar to a PlayStation/Saturn. It was intended to compete with those entertainment consoles. Not a bad concept; there was a lot of Amiga game software available and it was simple to port to CD32 -- just remove any dependency on a full keyboard. Unfortunately it came along just before Commodore went under, and was never really marketed in the US. It was a decent success in Europe. > PS: There's some amiga in the junk-parts section of our place here. > I'm > gonna snag it given the first chance. But it has no disks or power > supply.

The Amiga 500 power supply looks just like a Commodore 128 power supply, except the Amiga version has an on/off switch. It can use a TV as a monitor, but only in B&W. An RGB monitor is required for color. Amiga 500's go for surprisingly little money -- like $75 for a complete system -- so don't spend much on a PS. If it turns out to be dead, I need an internal floppy drive for mine... Kai

Help with Convergent Technologies

Is this a little square box cpu with a buss on the side? and ad ons that lock onto the side of it? If it is I used to administer a Convergent network, it uses the BTOS/CTOS operating system and uses JCL for batch programming.

Aquarius USR()

by BROBSTONA＠wartburg.edu

When I first got my Mattel Aquarius some thirteen years ago, I remember going through the owner's manual, typing in all the programs and all that. The manual documented the USR() function as something to execute machine language, which was "beyond the scope of the manual." I looked for probably three years (until I got my Apple IIgs and lost interest) for info on "machine code." The only place I knew to look was the public library, which, of course, had nothing. Does anyone know more about this? I don't have my Aquarius where I'm living right now to play with, unfortunately. -- Andy Brobston brobstona(a)wartburg.edu ***NEW URL BELOW*** http://www.wartburg.edu/people/docs/personalPages/BrobstonA/home.html My opinions do not necessarily reflect the opinions of Wartburg College as a whole.

Help with Epson PX-8

by kaikal＠MICROSOFT.com

Hi all, I just acquired an Epson PX-8, minus documentation of course, and I need some help. Questions: - What is the RS-232 DIN plug pinout? Or better yet, a PX8-to-PC wiring diagram? (Digi-Key appears to have the plug, part # CP-2080-ND for $1.22 - 800-344-4539) - Can I connect a floppy drive to the 50-pin connector? If so, what specs does it expect? - I assume the SP OUT connector is for a speaker; what are the A/D IN and BRCD connectors for? - Anyone have a spare PX-8 keyboard protector shell they want to sell/trade? Any other info appreciated, thanks Kai

Note to the wise: stay away from CRL Network Services. Everyone else, if your mail did not bounce, do not send another request. I have your request saved, I just did not respond to you.

Yes, I shall burn in the fyres of Hades...

by zmerch＠northernway.net

Yes, I finally got the fever for the flavor of a Pringles -- Dooh! I mean, the fever to spark up my CP/M machine... despite everyone & their brother telling me to check the PSU first. Yea, Tar & feather me, and ride me out on a rail... but I saved the thing >from Mr. Junkman, and it cost me $1.00 at an auction... Figured there wasn't much to lose. Here's what I have: It is *not* a Heath/Zenith machine.... It states simply on the front: Heathkit Computer. No nuthin' else. On the back, I found the Serial# and the number: H-120-1. I'm assuming this is the model number. It has two floppy drives (one of which the garage door is broken on) a full keyboard (which works fine, but is slightly sticky...) and an internal green 11" diag. mono monitor. Something tickled in my brain about those floppies, so as I lumbered around in the dark in my newly-begun clean-ish basement (Eeeeek!) I found my old non-working Atari 810 disk drive... and the mechs looked almost exact! Would these happen to be the same mechanically, would anyone know? Also, as there was no paperwork for this, so even the most basic, rudimentary info on this unit would be helpful... such as: which drive is the boot drive? Top or bottom? When I sparked it up, everything seemed to work, the tube came to life, and greeted me with a finger pointing to the right in the upper-left corner... and stayed there. Every key sequence I tried resulted in a "Beep" except <CTRL><RESET> which, of course, reset the machine and re-greeted me with the finger. Does anyone out there know what I have, and could you tell me? ;^> BTW, I (of course) would be in the market for a set of boot disks for this beastie...

That's what I did (in most cases). The modulator typically has 3-5 connections. They are : Ground (connected to the 0v line of the computer) Power (typically +9V - +12V) Video Input (Composite - jsut what you want) Channel Select (in the US - connected to the Channel 3/Channel 4 switch) Audio Input Most modulators are standard parts, and you can get data on them (or at least a pinout. I'm unlikely to be much help here, since I'm in the UK, and our TV system is different). Anyway, you need to identify the video input. Either look at the modulator data sheet, the schematics of the computer or trace it out by hand (eliminate the ground and power pins, and look at what's left). I've just found the (USA) CoCo Technical manual. The modulator has 5 connections, including the case. It's a UM1285-8 (I suspect that this is used in other computers as well). Anyway, the connections are : Case - ground 1 (Nearest the RCA socket on the modulator) - Video Input 2 +12V power 3 Audio Input 4 Channel Select Now connect a piece of 75 Ohm video cable with the centre wire to the video input pin on the modulator and the braid to the 0V line. Connect the other end of that cable to the monitor. -tony

Got a simple question. God I hope it's simple and does not turn out to be an advocacy question. Im planning my "museum" setup. I have alot of machines that were simply designed only to work on Color TV's. Is it possible to just tap the input's before they get to the RF modulator {built in} and use a composite monitor, of which I have dozens? Otherwise I've got to buy, scrounge, find, about 9 color tv's.
