Help identifying Mostek machine

Hello all,

 

I've come into possession of a Mostek computer (I'm pretty sure it's a
computer anyway) with a pair of 8" half height floppy drives (Shugart
860s) and three cards.

 

The cards are roughly 6x4 inches with a 56 finger edge connector on one
of the long ends and various connectors on the opposite end (I'm not
familiar with these). They are labeled MDX-FLP2 (plugged into the
drives - obviously a floppy controller), MDX-SIO (almost certainly a
serial IO card) and MDX-CPU3. The last card is the processor card. The
main chip appears to be a MOSTEK Z-80 clone which is labeled MK3801N-4,
Z80-STI AND ENG. PROTO. There are 8 4564s for 64K RAM on the card along
with what are either connectors for serial and/or parallel ports.

 

The whole box is about the size of a typical rack-mount machine with a
plastic case around it. Most parts are tagged as Mostek and most date
codes are from the middle of 1982.

 

Of course it came without software or documentation.

 

Is anyone familiar with this machine? Does anyone have a boot disk,
other software or documentation for it?

 

Thanks!
