Very cool, and funny enough I did come across that project during the first version but I had no idea what an FPGA was and took no notice of the tech at the time. I just wish they'd get on with producing official Commodore branded enclosures to house them. Apparently a dutch firm has licenced the brand but I've not seen any official Commodore branded manufacturing of the cases etc yet.
Any work done keeping the C64 and Amiga alive are well worth it so I'm very pleased to see this stuff, definitely brings a smile to my face, which sadly these days is far too much a rarity!
But yup, very cool, FPGA effectively means eternal life for the C64 and Amiga
