@Nathaniellockhart the annoying thing about this machine is that, with Commodore being Commodore, many of the ports are different from the C64, so you can't use C64 PSUs, joysticks or datasettes without adapters. Having said that, *some* Plus/4s have the same power port as C64s but I'm not sure how common they are. Funnily enough, I have an adapter which enables me to use my Plus/4 datasette with my C64.
