[rescue] Monroe OC 8820 and OS8MT

[Pete]

I just picked up a  Monroe OC 8820 but, unfortunately it came with no 
documentation or disks.  These were all in one CP/M boxes built in the 
early 80's that ran something called  OS8MT. I am looking for any 
documentation or software for this thing to get it doing more then 
holding doors open. It appears to be perfectly working other then not 
doing anything besides complaining about needing a system disk.

What little I know about the box I know from here:

Any leads to information or an operating system would be greatly 
appreciated.
