John, we all start somewhere!

The PCB numbers may not be as valuable as the part numbers on the 
chips themselves.  Are there any, and can you read them?

I wonder if this may have a 32 bit processor?  If so, the job just
got much harder.  I don't recall what year that car was made.
If it is 32 bit, and you still want to modify some code, it may be 
easier to go back to an 8 bit ECM.  If you are really green, and it is
32 bit, the learning curve just got very steep.

First off, does it make sense?  Like the first instructions from
power on, what do they do?  Do they init the stack pointer, init
some processor regs, init some memory, etc?
