Well, I finally got back here to check, and it looks to me like the thread is pretty much dead (no new posts for a few weeks?) ...

Since my limited electronics knowledge is so old and dusty, I guess I need more detailed advice than anyone with more detailed knowledge of the KIM-1 has the time and ...

"Hints" ... Checking various pins: Vcc (E-21/E-22 ...

Yep, pretty much started there ...

The only part that really says anything about the power supply itself,
is the "User Manual", which gives a schematic to home-build one, but
they don't really explain ...

Well, I'll just apologize now for being a newbie ... And for a long post ...
