There's a (if _I_ remember correctly) model TM100-2 and a TM100-4, SSSD and DSSD. Someone here on the list, I think, has the ROMs for a Kaypro-4 to let it use DSSD drives. Cool. If you _do_ dig them out, I would perhaps like to get a copy as well. I picked up a large box of Cromemco boards at Dayton this year for $1/board plus another $1 for the 8" drive (with motorized eject). The seller left the box and PSU at home, unfortunately. So I have this Cromemco system minus the shell and transformer, but I have the backplane and the drive and all the cards. I do have a box to stuff the cards into for testing - my sister-in-law works at the local post office and a customer mentioned having an S100 system he wanted to find a good home for... It appears to be complete, with two 8" drives, a video card, etc, but with no software, I haven't done much with it. I have CP/M on 5.25" disks for the C128 and the Kaypro, but no CP/M on 8" for anything. I've never even _heard_ of Cromix. Is it Cromemco CP/M or something completely different? I remember the Cromemco ads in old Byte magazines. Since I was a) a poor grade-school kid and b) into PETs and Apples, they never appealed to me, but I do remember them. Maybe if one of my friends' fathers had been a CP/M user, I might have picked up some interest earlier. Are there docs on the web for Cromemco boards? Mostly, I care about jumpers, etc. I don't think I _need_ schematics yet. Thanks, -ethan __________________________________________________ Do You Yahoo!?

Unfortunately, that hard drive crashed shortly after the system was exhibited at VCF 1.0, before I had a chance to try to back it up. One day it'll be my first hard drive recovery project.

The TM200 and TM201 were rare; I'm not sure if they ever actually made it into volume production, although I had data sheets on them at one time. I've always wondered what happened to the FD55-C and FD55-D. The FD55-GF is apparently still in production, but the other FD55 models are long gone. I've been looking for NOS FD55-B drives, but haven't seen any in quite a while.

Curt, if you didn't get any software with the machine, how are you going to get the Atari specific functions of the machine working again?

There was a 6502 CPU card. The system had the POKEY, ANTIC, and CTIA chips, but I don't recall whether they were on the CPU card or a separate card. The memory card was a standard S100 card. In principle, you would be able to run at least some of the regular Atari 400/800 software on it. The disk controller in the system was for development use only, and was NOT compatible with any regular Atari disk controller, although you could write a handler for it, and perhaps Atari had one. But you could hook up an 810, 1050, or the like just as with a "normal" Atari. And of course the EPROM programmer was not a standard Atari 400/800 feature. About ten years ago, I bought a binder full of docs on the 400/800 dev system from Weird Stuff Warehouse. Unfortunately the system itself was nowhere to be seen, so either it had already sold, or was in the back warehouse somewhere, or (less likely) Weird Stuff only got the docs. I still have the binder. It's somewhere in a collection of about 400 Conticos and boxes, and I don't know which one. Eventually I'll find it and get the stuff scanned. But if what you have was really for 2600 development, I don't know anything about it. Given how early the 2600 was developed, I'm dubious that they would have used S100 gear, but it's possible.
