JP1 Remotes

I soldered one of Rob's eeproms into a 6131 two weeks ago. Assuming the eeprom is the same one that I installed...

As you noticed the white dot is actually the manufactureres logo. None the less it is indeed near pin 1 (at least it was on my chip). If you look very close (this certainly took a very ...

Also,
Getting the 6131 open was kind of a bear and in ...
