switching between EPROMS

[Jody Shapiro]

There was a company (Adaptive _______ ???) that used to make a product 
called the PROMPaq (I think) for the GM ECM's that would allow you to 
switch between up to 5 EPROM's using a rotary keyswitch. I believe that 
you could even do it while driving.

There were articles (and a few installs) in magazines like Hot Rod, Car 
Craft, and Popular Hot Rodding a few years ago (1990 - 1993)
