So, my next step is to track down a schematic for the
machine, and see
what I can figure out. I'm guessing I should look first at anything that
deals with the high four bits of memory. Thoughts, suggestions and
intuitive guesses welcome!
If the machine IC's are socketed, pull them one of a time and reinsert.
This simple procedure does wonders :o)
