I have finally rearranged my work area to include my 800XL. I have it hooked up to my iMac with SIO2OSX, so no drives are needed, and I can even print, via the software, should I need to.
Spent half the day playing some old favourites on a real machine, with my trusty Atari joystick instead of using an emulator with my USB stick.
Good times. Playing Boulderdash took me right back to nineteen-eighty-whatever, it's still just as challenging now as it was then.
