Need the serial protocol for a 1995 LT1 B-Body

[cputalk]

I am pretty sure it is OBD-I

It is a 1995 Chevy caprice X police cruiser.

I am interested in the documentation of the serial protocol...
for monitoring... I already have a scan tool..

I want to make something (microcontroller based) for monitoring.

I used to have the serial protocol in 1999!

But my hard drive crashed!
Does anyone have it?

I would assume it's running a similar setup as the 94-95 LT1 Fbody's and C4's. Those are very similiar to the Impala SS car's and they use the same setup as other LT1 car's.
