Had a rummage around some old boxes yesterday just to pass the time and came across my old Korg SQD-8 Midi Sequencer.
It was a pain in the butt to write with and it only stored data on 2.8" 'Quick Discs' but I came up with more tunes on it than any computer based DAW that I own now, whether the restrictions it placed made you more creative or I just had more ideas then is up to discussion - but I did enjoy using it, that's for sure. Shame the crummy disk drive gave up the ghost, I'm sure I'd probably still be using it now otherwise.
Here's the sales brochure
Here's the very chap...
