During my random internet searches I came across some PAL dumps for a rare version of an Amiga 1000 motherboard.
I still don’t know completely what this board does over an original.

After contacting a few people from the forums asking for permission to offer these up for download I was given the name Andrew J Wilson who is the developer of the board.
I cant seem to find this guy to ask his permission so, Andrew if you ever read this and aren’t happy with me hosting them just let me know.
The files are in a .zip file and there is also a dump of the SCSI controller EPROM in there.

Thanks to jopower from the a1k.org forums and DonutKing from Vintage-Computer.com forums for their help.

Today, for no reason other than proving to myself I could, I manually reverse engineered a PAL22L10 from my Street Smart board.
The PAL at location D11 was the only one on this board that was security locked so until now I couldn’t copy it.
Using the ABI to test I went through each pin individually and derived equations.
After my first attempt I thought I actually had it sorted but…..

Altogether it took quite a few hours to do so will probably not do this too often but the option is there should I need to but finally the game booted up and all the outputs on my clone match the original.

MrDo has sent me the equations for the PLDs at 7C and 2N.
I already had the ones at 7C but his equations can be seen in the comments to the first Pole Position PAL dump post.
The second dump from 2N I did not have and I have compiled it using WinCUPL.
I dont have a PP board to test this but MrDo has confirmed it working so will be marking it as Tested.

Thanks MrDo
