I think that the Raspberry Pi could be quite the little powerhouse for a lot of 6502 projects as a disk drive and there are other components on board and it could easily do fetch with those components for the 6502.
Raspberry Pi as a disk drive for a Commodore 64 @Raspberry_Pi #piday #raspberrypi

A video which shows the software I wrote for the Raspbery Pi to let it act as a disk drive for a Commodore 64. I’m able to get directory listings and load software from the Pi right onto the 64. There’s only some level shifters being used, the Pi is doing the IEC protocol directly. No arduinos or AVR or PIC microcontrollers are used.
