The new #Commodore 77 uses an Artix XC7A100T instead of the XC7A50T used in the Commodore 64 Ultimate. It has twice as much of everything, except I/O pins (250 vs. 300). Is this really just necessary to reach the fabled 77 MHz, or might there be more behind it? #Commdore77 #C64Ultimate #C64U #retroComputing
