- Mar 4, 2006Hi all -
I've been lurking here a while, just acquired some S-100 junk, and thought I'd
take the opportunity to say hi.
As an introduction, I still have most of my old computers: a TRS-80 Model I,
Apple IIe, Macintosh Plus, Mac SE, PowerMac 8500, a Next Cube and a Next
Pizza Box. Sadly, my old S-100 systems are long lost (and with collector
prices the way they are, never to be replaced!). Armed with a new-old
oscilloscope, I replaced a bunch of dead chips on the TRS and IIe so now all
the systems work again.
Recently, I acquired a huge old boat anchor of an S-100 system. It has no
labels or obvious identifying marks of what is was or who made it. It has
three S-100 boards. First, a Sierra Data Systems (no model id) Z-80
processor board that has onboard memory, a connector for floppy disks, CRT
(?!?!), printer, and one unlabeled connector. The second card is a PMMI
modem. The third is a Percom serial card with terminal and tape
connections. There are two Qume 8 inch floppy drives. The system also has a
huge power supply by "Integrand" (who may have integrated the box), which ran
CP/M when it worked. I also got a Heath H-19 terminal with it, but that
needs some work (dying vertical deflection) to get back to working.
Anyway, hello and if anyone has any ideas about this system or suggestions on
where I'd track down the right CP/M to run on it, let me know!
