Nope.. GM calls mine a P6... It's a single processor (though there is a
"timing chip" that appears to be a 2nd processor of sorts), single board,
EPROM based PCM.  According to GM, P6 refers to the type of processor...
the HC11F1 is designated P6 by them, but they also state that it was
discontinued in 96, so I'm confused... Possibly the newest is a variant of
the F1 and it's a P7 or P8?
