I'm thinking of starting a thread with resources for newcomers to classic computing (not DOS/x86 variants, more Commodore/Atari/Apple etc.). Since it can be hard to know exactly what model type/amount of RAM/processor/speed/BIOS revision will best work for you, and what parts (disk drives, casette drives, mice, joysticks) are needed to get started. So if someone could contribute some links, or perhaps write a guide of their own, please post it here!
