Transistor part number is 2N1218. Or does the 430 refer to the factory the transistor was made? or other?
Photo of transistor posted in the photos/Josh Bensadon folder of this group.
I've seen some IC's with only a 3 digit code on them (not part of this analog computer). Case in point is the following:
RCA H 650
Is that to mean 1976 week 50?
H being the factory where it was made?
