Hi
It was a ROMed version of one of the FIG varients that was
popular at the time. I don't recall which one.
I may try to power a module up and add a serial terminal
to see what it is. As I recall, the power module also had
the reset circuit and backup battery for CMOS RAM ( the
problem here ).
I don't have the pinout for the modules and without the
supply working, it'd take a while.
None of the ICs are in packages. They are all mounted
under black blobs on the PC boards. This was done to
keep it small.

ask about these.
These were small modules that plugged together a little like PC104,
as a stack. National Semiconductor made them. They used the NSC800
processor.
I have several modules but the powersupply module had a battery
leak that destroyed some of the PC board and components. I was
wondering if others and any knowledge of these modules?
These are kind of cool, one I have came with Forth built in.
Interesting, that'd be an 8080/Z80 Forth. Know anything about the Forth?
