Besides replacing the relay system, the requirements listed by GM for this controller included: 1. A solid-state system that was flexible like a computer but priced competitively with a like kind relay logic system. 2. Easily maintained and programmed in line with the already accepted relay ladder logic way of doing things. 3.
