With the half hearted approach the casino and our slot tech take they
don't remove and replace the whole machine for me to examine.  I got
only the PIC chips sent back to me.  I believe I checked them right off
and the EEPROM read correctly and not as all zero for those three bytes.
With code protect on that meant I believe I put the chips in a board and
homed the reels and they didn't go to zero.

But yeah I better check to make sure I did that right.

Checking that now.  I've gotten to used to being able to just set wait
states.

I appreciate the help guys even if I forget to say it in each
message....
