Hi Everyone,
I'm looking for a Computer for IROC. I need a good functioning computer specifically from an '87 TPI 5-speed. Anyone have one?
Thanks!
Erik

FYI, the computers are the same part numbers from 86 to 89. The PROM inside is different, but I think you could use one from either an 87 or an 88.
