Re: Creating JEDEC files for PAL/GAL

There was one built back in the day, but I haven't been able to find any pictures or details other than a reference here and there. There is someone at the TPUG meetings who may have one and he's looking to see if he can find it.
 
In any case it would be nice to see a new solution. I'm sure it will be a lot smaller than the original.
