Micro Men on I-player - brilliant entertaining stuff and great performances by Alexander Armstrong as Sir Clive Sinclair and Martin Freeman as Chris Curry of Acorn Computers.
I confess to being a long time fan of Sir Clive Sinclair and always held his achievements in high esteem .... yes, even the C5 which was an "epic fail" yet a visionary experiment at the time (half the population over 60 now appear to ride around on electric trucks). He always seemed brave enough to attempt the near-impossible and when his ideas worked, such as his first pocket calculator, they were truly ground breaking.
I remember staying up all night playing with my first Sinclair Calculator in the early 1980's and later the Sinclair ZX80 with its fabulous 1k of memory which is almost enough storage capacity for this sentence. I was one of the first people to order a ZX81 and therefore one of the first to be queueing up at his service bay in Cambridge to have it repaired. In the early 1980's I was probably the biggest Sinclair Nerd in Norfolk.
