The most ridiculous thing about the C64 was the super-slow disk drive interface. There's a saga about that because it was supposed to be interrupt-driven using the serial interface in the CIA I/O chip to transfer data over Commodore's cut-down serial version of HP's IEEE-488 aka GPIB aka HPIB interface. The PET used GPIB for its disk drives and they were fast, but those cables are thick and expensive. The "IEC bus" with its daisy-chained DIN cables is much cheaper and better for a home PC.
