Did R1C have bodge wires on the bottom ? Looking at my files I did other revisions...

R1F looks like I got those made at JLC, but no idea if those were tested.

Thanks, yeah there is some swapped pins on the R1F, so likely those wire fixes. Also looks like a huge layout tidy up as well.

One thing to bear in mind though, I have no idea what firmware goes into these things any more.. unless it is posted in this topic somewhere...

Possible maybe @rubber_jonnie could read and dump the versions he has at some point, firmware may all be the same, but no idea after all these years..

If the chips came with the kits, then there's probably no point doing anything @rubber_jonnie Theres no more of those boards out there AFAIK.. and if chips came with them anyway..

The firmware definitely changed a fair bit in the last revision (R1F). It looks like I was trying to use the smaller 1504 PLD, but it wouldn't compile, so I had to move a few pins about to get it all the "fit". The last code revision looks to match the last PCB revision (R1F) so I assume it was just left an estate workers literally need building and testing..
