However, a lucky eBay auction later where I am the only bidder landed me with this little beauty.
Meet the Oric Atmos - a relatively rare 48k alternative to the zx spectrum from 1986 that just missed out on being popular. This computer sold well in France, and used a 6502 processor like the c64. This one is mint condition, boxed, and came with several useful books and (not so useful cause they don't work) cassette tapes - purchased on eBay of all places. Who'd have thought?
Memory: 48K (well, 64k actually but that's taken up by BASIC and needs hacking to get at)
CPU: 6502 @ 1Mhz
Cost: £150 from ebay
So, now all I need is a joystick expansion and something to load games into it that doesn't take 500 years to load and crash out half way through..
