Does anyone have, or know where I can get, a manual for
an IMSAI MPU-B 8085 card? I have an IMSAI system based on this card that I am try to get running. You can see photos
of the system on my web site, www.dvq.com, under "Old Microcomputers".

Thanks,

Bob

Bobar,
I can't help you with the manual but you do have an impressive collection of S-100 machines. Wow!

Okay this did take a while. I had a look at my IMSAI cards collection ...
shameless plug#1
http://maben.homeip.net/static/S100/IMSAI/index.html

Sure enough I only found the MPU-A card. How annoying.

Then I remembered that Fulcrum computers in England used to re-badge the IMSAI stuff. So naturally, here it is their manual

MPU-B manual (http://maben.homeip.net/static/S100/fulcrum/cards/Fulcrum%20MPU-B%208085%20CPU.pdf) ..

Actually I have a suggestion, which is the CompuPro or Godbout 8085 CPU cards will probably be more available. Have a look at this documentation (http://maben.homeip.net/static/S100/compupro/cards/CompuPro%208085%208088%20DUAL%20CPU.pdf) which includes a circuit diagram or two.

------------------

So with that good deed done could I make my shameless request#1. Anybody with any of the following manuals in scanned form please forward them to

Thanks amouse.

The monitor instructions in the MPU-B manual were a great help. I now have everything working except the disk system. It just respinds with "NOT READY" every time it's accessed.

At least I now know the momory, CPU, and I/O cards are OK.

On to the disk controller!
