Card identification required.

I have just recently picked up a Tandy Color Computer 3 (which I have nicknamed "Spectrum") at a local thrift store. After opening it up, I found an internal card plugged into some connectors on the system board. The card does not look to be a Tandy add-on. The unknown board bears a name of "DISTO CANADA" & has 16 Mitsubishi M5M4256P chips on it. What is this card? Is it some sort of internal RAM expander or internal disk controller card? Any help would be more than welcome. ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.
