[Coco] eBay MPI Heads Up

[K. Pruitt]

Thanks Barry.

Due the age of the PAL selector board, I think I'll just remove it and put 
the PAL I have left over from the upgrade of my white 26-3024 in to this 
grey 26-3024. This will restore it to the original configuration. I can 
always swap the PAL chips if I change my mind and want to use it with a Coco 
3 in the future.
