16188051 IC contents

[Dave Hempstead]

I don't usually like to cross-post stuff, but I've posted this
to both the DIY_EFI and the GMECM, since it might be of interest
to both.

I received a PCM for experiments.   THANK YOU SCOTT KNIGHT.
It is out of a '94 Caprice.  It is the same number as
my PCM from a '95 Camaro.  Here is what is in it:
(I've only listed IC's, excepting the power IC's,
and the numbers printed on the boards).

Next step, id'ing each chip.
(I've gotta believe 2 of the 68pin PLCC packages are the 68HC11F1 and
the IO with RAM chips)
