3 Days later, i had some LS373 in the mail.
Quickly put one in, works perfectly!
Having it running now for a longer time, it still works so i think i can
announce sucess finally!

Part3:
What happened?
What causes a LSTTL Output to resistively short to GND?
Can the condition reappear?
Can this happen to other parts too?

Regards,
Robert

I have no idea of what caused the problem. Faulty IC I would imagine, but I
did indeed enjoy reading the story. You did a good job, Bob.
