Most recent revision dated July 31 2008. Corrections appreciated, more S-100 owners requested.
I'm Herb Johnson, in New Jersey USA. I provide some support services for old S-100 (IMSAI, Altair, Compupro, etc.) computers and also floppy disk drives. For more information on what I have available, check my S-100 Stuff Home page.
This page has discussions from S-100 system owners. They describe what they have, or why they are interested in these systems. There may also be some S-100 owners in my links to S-100 sites page. But this section will generally be for people who own and operate just a few systems and don't have their own Web sites.
Check my Morrow Web page for discussions of Morrow history by Marc Kupper, a former Morrow staffer; and Robert Parker formerly of the Los Angeles (CA, USA) Morrow's User's Group.
Rich Cini of the Altair 32 emulator and USB-based Altair front panel, describes his Imsai system with iCom floppy controller on this Web page. The iCom controller is a very early, pre-S-100 floppy disk controller, with an IMSAI/Altair interface card and with iCOM's own OS.
Bill Degnan of "vintagecomputer.net" has a Cromemco System One he's working on since late 2006. Here's his discussion and photos of it. He has a lot of Commodore stuff on his site, among other systems. HIs other S-100 systems include NorthStar Horizon and MITS Altair 8800b and IMSAI 8080. Look for other S-100 systems on his site. Most of these are described in a blog/diary sort of way as he works on them. Lotsa photos.
Rich Camarda has several running S-100 systems. A Compupro running CP/M 86, Concurrent DOS, and CP/M 2.2 on a Seagate MFM hard drive. Also, a Cromemco "System One" that can run CP/M 2.2, CDOS, and CROMIX PLUS, with a WDI-II set up. Another Cromemco system with an STDC hard drive controller, set up to running the same CROMIX PLUS and CDOS. Also, a S-100 box with a CCS 2422 floppy controller system with my modified CCS BIOS running with a Cromemco ZPU and TUART, and a Diablo 630 daisy wheel printer. This is the system I put a GIDE (Z80 IDE controller) on. He also has another S-100 box with several CCS boards; check my CCS Web page for details. He says "I still have the Morrow S-100 boards, but have not got the MPU-Z80 to work yet. I also have 3 versions of the Disk Jockey controllers, but I can't get them to work." He's looking for the Morrow DJ boot disks, which I have. - Herb
Greg Bober in Michigan shows his IMSAI PCS 80 system. He has photos of each card, the system and screen shots of the VIO's video display. Greg's site is mostly about his interest in small-scale railway.
Robert C. Kuhmann was an early customer of Cromemco, and knew the founders. He built an early CP/M based BBS system with Cromemco products. He told me his story in Jan 2008, and it's on my Web site at this link.
Larry Ryan of Washington State has a long history with S-100 and with Intel processors. Read his story from 2008 on this Web page.
