When I first started using computers, everything was physical and there were many early computers like the ZX series (Spectrum, ZX-80, ZX-81), Oric, Dragon, VIC-20 and many more. These systems are old, although many are still serviceable and you can still get them. However a better solution (thanks to lots of hard-working people) is to use a simulator. This page tracks computer simulators and software you can get to run on them – mostly games.
