Not a complete history!
The BBC Micro is hardly mentioned. And what about the Nascom 1 and 2 systems which, fully built up, was capable or running CPM. I built a Nascom 2 for my girlfriend at the time!
Also the UK101 was a ripoff of the Ohio Superboard - I have mine in the garage! I bought my Ohio Superboard from a bloke in a semi-derelict squat in London. He was importing them wrapped in silver foil in a suitcase!
