I will buy three. I would like the LEDs for power, reset --IRQ?

Note that some use GPE's Quickscan for diagnostics which uses the TC1 buss.

Received my Piggydeux today for beta testing. I have a Genesis that was booting intermittently and was passing the Quickscan80 tests consistantly and is no longer booting to attract. I highly suspect the original daughter board as the
problem and was not looking forward to removing it.

I generally remove the daughter board and replace it with a GPE replacement daughter board. Unfortunately GPE is out of stock for most of the assemblies offered, likely due to having to work for a living.

I pulled the game prom from the MPU without removing the MPU as I have a handy-dandy chip puller that works great on
24 pin chips, and struggles some on some sticky 40 pin versions.

I put the game prom in, oriented pin 1 as indicated on the board -- which is opposite of the TC1 socket orientation. Put the
PiggyDeux on the MPU and powered up the machine.

And behold, the machine booted into attract without problem. The Piggy power LED is green, and the reset is retina burning orange. Really bright for such as small LED. Nice to be able to fix a daughter board problem without having to remove the
stubborn thing.

As I go through this machine I will report on the longer term application for the PiggyDuex.

So consider PiggyDuex as resolving a Gottlieb 80B MPU daughter board problem.
