I'd like to revisit my youth and play some old Acorn Archimedes games. Is it any more complicated than buying a Raspberry Pi and downloading RiscOS onto an SD card? I can then attempt to plug in a floppy drive or download games online.
If it's not this simple then I won't be offended if someone tells me that straight up! If it is, can anyone point me in the right direction for getting the right Pi and the operating system on an SD card?
