The remains ( mostly just the PCB's ) from an
early Fairchild Sentry test
system were junked today.
The PCB's are brimming with early ( 1974 datacodes ) Fairchild TTL ic's. (
(9xxx and 93xx )
Also ECL of course, but I don't do that !
Any worth looking for, in particular w.r.t. to keeping old PDP's running ?
Very few TTL chips are actually rare, so the boards are probably more
important whole than as parts. MECL III parts (MC16xx) are getting a
little scarce, however. MECL I and II are getting very scarce, but by
1974 they were obsolete and out of fashion.
There is a very small community of test equipment collectors out there
that might want these.
