I've been designing IC's for over 30 years now, and this is definitely one of the most unusual I've ever seen. This appears to be from the 1976 to 1980 timeframe, and having to use multiple die to implement such a simple logic function shows that the former USSR was behind in their process technology. Intel's 8080 CPU debuted in 1974 and had 4500 transistors in a single die inside a 40-pin package; the K230IK1 was at most a few hundred transistors and required at least 7 die (maybe more; photo is chopped-off).
A lot of work went into assembling these; I hope you can get some of them running. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
