I have now replaced about one hundred and fifty TI chips in the Modcomp's CPU
and memory planes. I'm about 3/4 of the way through the process - and the
MODCOMP is becoming very reliable. It will run basic memory diagnostics by
the hour without failure.
Why not simply re-tin the pins on the TI chips? Shouldn't be too bad
if you've got a solder pot.
Just wondering...
