Looking to buy a spare prom for my 1989 IROC-Z. I'm ready to start playing with prom burning and I'm going to take the original one out and store it so if I mess something up I can always put my orriginal one back in. After I know more of what I'm doing and get comfortable in Prom Programing I'm going to use 1 for a race prom and 1 for daily driving. Anybody have a spare prom Please let me know as I would like to get one ASAP. Also if anybody has a use for a 1984 Z28 computer and prom let me know I've got one collecting dust in the garage. Thanks cabsales1
