The Atari 800 looked like a typewriter with nowhere to put the paper, but it wasn't a bad machine in its day. I've still got mine around somewhere. The top lifted up on the Atari 800 to reveal a cartridge slot, making it similar to the Atari 2600 console for game playing, but there was also a dedicated cassette deck which would also load bought games. You could also used the cassette deck to save any programmes the user created. I did my first ever programming on this computer, using the BASIC cartridge.
