What kind of EPROM does GM use??
The EPROM programmer I am using needs to know the manufacturer of the chip being used. Who makes the chips that GM uses?? The EPROM is from an 87 IROC.
Thanks

Just choose any generic 27C128 PROM. It doesnt really matter that much as long as the programming voltage is 12.5Volts.
