So what's going on with the #65uino at the moment? Nothing? 

Actually, quite a lot! I'm using it as the prototyping platform for my #Relatively Universal ROM Programmer and wow do I have news about that. 

I've written the 6502 assembly code to program Winbond W27C512's, which are some of the newer-ish ROMs, electrically erasable and all that jazz - as well as the 2732A's which are a bit older, requiring UV-C for erasure and 21 Volts for programming.

Either way, successful proof of concept and I now have PCB shields coming from a manufacturer - oh how I hope they work.
