I don't know the MDC-II, but if it's
actually an Andromeda DMDC-11,
that's a Qbus controller for 5.25" floppy drives.

The M7380 module hasa AY5-1013 (UART) on it, but no connector for a cable...
The MDC-II is only partly populated with what I think is sockets for E-proms,
and If I where to guess you could populate it to be a serial interface and maybe
some kind of interrupt timer? The board has no external connector but has
room for one.
