Or do what I've done in the past to replace an obsolete TTL part - shoehornStandard low power TTL, yes. However, very obscure part; single J-K
in a modern part. If it is a JK, use instead a dual JK such as an LS73.
Solder or plug in power and ground, then cross wire the other pins into the
original '72 connections. Might have to be careful with preset and clear
connections - but beyond that it should be possible to stitch something
together that works.
Last thing I resurrected this way was my HP5328A counter.
