Help identifying Mostek machine

That sounds like an interesting machine. I have a United Technologies
Mostek Matrix 800, but it has a 1.2meg 5 1/2 drive and an MFM hard
drive. My machine runs CP/M and has a Z-80. I have the system disks,
albeit on 5 1/4, and I can make copies for you if you need them, but
you'll have to find a way to either convert them to 8" or to hook a 5
1/4 drive to the computer, but even then I don't know if the disks
would be compatible.
