I just need some moral support, as my unit currently doesn't work. Probably an easy
fix. I do have the whole deck out though, floppy cabinet, expansion cabinet. Monitor.

New subject: Anyone with information on the NA2000series modules?
Hi
A post in another group remined me that I should 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?

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.
