I had an Archimedes, the first Arm machine, in 1988 or so. It was marketed as the fastest microcomputer in the world at the time so I think Acorn knew they'd hit on something special. I was 14 and used to write games on the BBC Micro Model B and so upgrading to the Archimedes with it's speed, Sprite system and millions of colours was like suddenly being let loose in a huge unbounded creative arena. Good times.
