OK, just safely brought home this beauty with Tuxie's help. Thanks a lot!

It starts up and displays "insert monitor disk"

I haven't looked inside yet to see it the rom(s) are socketed, but is there anyone with the right equipment/knowledge to dump 8" diskettes and rom chips?

The guys at kryoflux.com can probably dump the 8" disks... they have some drives and the knowledge of ancient disk formats smile

Getting the ROMs dumped should be the easier part, virtually anyone can dump chips from that era...

OK, I took some half-assed pics of the pcbs:

PCB photos

Can you identify anything dumpable there? There's an additional PCB with a socketed chip on it which I can't reach with the camera. It's 24 pins with a sticker that says: "104521 F".

The 8" floppies are:

*Microsoft Basic version 521 - 2 copies, 1 with the seal sticker intact
*Microsoft Multiplan version 105, 1 diskette
*Microsoft Basic Compiler version 530, 2 copies both with seal sticker intact
*Microsoft Fortran-80 version 348(?), 1 diskette
*Microsoft Cobol version 466, 2 copies both w intact seal sticker

Manuals/documentation:

*for the above mentioned software
*owners manual for the computer
*CP/M MP/M
*Pascal MT+
*BDS C User's guide

Then there was a box full of 8" floppies which I forgot to bring frown
I will probably go and pick it up later.

Important would be something like a technical manual, anything of that sort in there?

Looks like everything that is required to emulate that computer is socketed: EPROMs, PALs/GALs, and one big chip that I couldn't identify. Or, to put it the other way, everything that is socketed (again, probably with the exception of that big chip) needs to be dumped ;-)

The IC you mentioned (on the additional PCB) is probably an EPROM too, so this also needs dumping.

The manuals are a nice find as well, the guys at bitsavers.org are probably interested in them, you can probably get them scanned and preserved by them as well

There's a "Specifications & Installation Guide" with schematic drawings of the PCBs and other stuff. I'll scan that later and upload. I'll be willing to scan anything that there is interest in, in time.

What's the location of that one big chip you mention?

P1010038.JPG, on the bottom. It has MOSTEK printed on it, and while I can't identify the number(s) I guess that it's the processor (or a coprocessor) since MOSTEK manufactured mainly CPU clones (and DRAMs)

I think it says MK3801N. Unfortunately, that part of the picture is really blurry.
