I am not home right now - going thru a pile of stuff I have stored
elsewhere - and came across some logic I am not familiar with. MC5xx from
Motorola ring a bell? This is the oldest logic IC system I have
personally seen, as the chips have 1965 datecodes (!). They are part of a
Doppler processor for the obscuro AN/KPQ-1 radar set.
The oldest Motorola book I have on hand here is their 1971 Master Selection
Guide, and those numbers appear on page 122, under "MTTL I". If you'd
care
to call out specific numbers I can tell you what they are.
