Refresher course on '89 ECUs, please? 200 1989

I don't have much experience with the post-'85 cars. Just picked up a parts car.

IIRC, '89 was the year with flaky ECUs. There is a 'bad' ECU, and the service replacement part ECU.

Or am I thinking of a different year, or something? Which ECU is which?
