That brings up a good question, where do you find them to repair core memory

one example is the Apollo AGC used nothing but 3
input RTL nor
gates if memory serves.
Almost every reference claims that it only used the three
input RTL NOR
gate, but they're actually incorrect. It contained two kinds of chips,
the other of which was a core memory sense amplifier.
