They ran ISIS but CP/M was ported to them as the first system and standard

Actually, those 8" disks could be from any number of several CP/M systems.
A dump of a system disk will sort that one out.
DRI even distributed MP/M (in its OEM package) as hosted on an MDS-800.
Sort of minimal (MP/M was intended for systems with more than one terminal
and bankswitching memory), but made possible by the 8253 timer periodic
interrupt.
