The chips are mechanically very fragile. I'd rather replace them than rely on
solder to keep them together ;-)
Also, since so many have pins break off when they are removed from their
sockets, it wouldn't be a worthwhile exercise...

"Black holes are where God is dividing by zero"

began to debug the
MODCOMP - one
chip at a time. After finding 20 or 30 bugs - ALL
of which were TI chips
- I finally "relented".
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
