Thanks for all the help. These are the things I learned today, about RPO codes and I also found I was wrong about some things. I have the following:
L05 code=5.7L TBI
GT4 code=3.73 diff
M30 code =4L60E trans
NA1,NA5 code= <8500 GVWR, Federal

I'm going to pullput the computer and look for the PCM id number, I think its 1619747, but I'll find out. I'm sure of the 8192 now, I got 2 Max232 chips out of old instruments at the plant today, so i'm going to build up an interface

Thanks
