Subject: Jade S-100
Since there doesn't seem to be a comp.sys.S-100, this seems to be the
next best place to post this...
I've got a IMSAI S-100 box, with a Jade "BIG-Z" Z-80 CPU card, and a Jade
"Double-D" disk controller, rev. C. I picked up a rev B card in surplus,
and it doesn't seem to work. Before I go trying to borrow a good scope
and/or a logic analyzer (both would require calling in past favors) does
anybody know if the s/w I have on my rev C. will work, or do I have to start
hacking (again...) ?
Anyone know what mods need to be done to the IMSAI to allow it to run IEEE 696?
Lastly, there are times that I can't get the mess to boot. If I pull the
extra boards out (Semidisk, Godbout Interfacer 4 (triple serial & Centronics))
to a bare minimum (CPU, 64k Godbout RAM 17, floppy controller) it boots ok. I
can then shut it down, plug in the other cards, power it up, and reboot with
no problems. Any ideas?
I have a Morrow "Switchboard" for sale, with docs.
I'm looking for docs / bios code fragments for the following:
Compu-Time T102A calendar/clock card
California Computer Systems 2805 calendar/clock/terminator card
" " " 2720 multi-port paralell I/O card
" " " 2830 6-port serial card
Macrotech "MAX" memory board (no part number visible)
Mullen "TB1" extender/logic probe (what chips are used ie logic probe?)
Memory Merchant MM16K14 memory cards
Qume DT-8 drives
Any help would be appreciated. I am trying to bring up two systems for local
organizations - I know that some of the stuff mentioned above is old and
not worth much, but when you've got lemons...
