Any interest in Mad Planets/Reactor interface PCB blank?

I finished this up at the end of last year, but once I had one built, I didn't have a Mad Planets to test the populated board in. So it sat...

Then Bill K. asked about them a few weeks ago and last night finished testing on his setup. He was able to test the PCB blank for both a Mad Planets build and a Reactor build and it worked for both.

- To explain this further, it's a Mad Planets Interface PCB, but it can be built up either for a Reactor or built up for a Mad Planets since it's basically the same circuit.

---Also, and I haven't tried this, but I think you can turn a Q-bert PCB into a Reactor or a Mad Planets by populating some of the empty spots on the Main PCB. I haven't looked at this for about 4 years, but I remember thinking at the time it was possible. It was the interface PCB that was the hard part to get and kept you from making a working game. I know there are some minor differences in the sound PCB, but I can't remember what they were.

So would there be any interest in these? I was thinking around $35/each shipped.

Here are some photos of the boards. The first is one populated by Luke as a Mad Planets. The second and third are screenshots of the switch test mode showing the spinner asterisk changing position (short of a video, the best I could do). The last picture is of a board I populated for my test bench that can be used either for Mad Planets or for Reactor. They both work well. To make this exclusively a Reactor interface board, populate everything but omit the connector and components left of connector P2.

So with this board, you could convert a Qbert into a mad planets board. If so, I would be interested dependent on price.

Not true. This is the interface board for the spinner on a Mad Planets or for the trackball on a reactor that connects to the main PCB through a 20 pin ribbon cable. This board is usually missing and is hard to find.

You can convert a Qbert main board into a Mad planets main board by a couple of jumper swaps and replacing all of the ROMs and adding two more roms. Same is true for Krull which can be made into a Qbert or a Mad Planets or vice versa (can you say "vice versa" for three things?).

Any idea what the jumper swaps are? I managed to get a Q*bert board to boot Mad Planets after rom swaps exactly once. I need to look into the jumper differences and see if I missed something.
