the EEC IV ECM's all use a proprietary PROM which is suppsedly totally
different (pinouts and voltages) than any standard part.  I've never
played with one, but from what I understand there is an interface port
on the side of the box where you can plug in a module with its own prom.
This is what the aftermarket PROM makers do, sell you a module to plug
into that port, and the module interfaces a standard prom.
