I'd love to see Ken Sherrif do a teardown of some vintage ECM.

Crazy Honda fact: all their ECUs from 1992 (P05) onward had full facility to drive individual coil on plug, but officially Honda switched away from mechanical distributor in 1999 (S2000?). You can trivially convert 92 car with a small adapter board, ECUs shipped with all the needed firmware and hardware in place sitting unused for 7 years.
