Those were the days however when a lot of people still have dreams of a prosperous and successful Britain.
They had the chance but either shoot in foot or had bad luck and timing (just like UK car Industry )
Clive Sinclair persist to build his computers so cheap as possible,
Also He ignore his engineer that explain were not ready or that would not work, follow by something that screaming Sinclair trow at there heads...
So get ZX Spectrum and QL those Microdrive instead working disk drive
Also reason why
BBC Computer Literacy Project not take the ZX, because not match any points of there needed specification.
That reason Acorn got BBC Micro and not Sinclair Research, Dragon or Oric...
But Acorn had bad luck with Electron who was not ready for important Christmas sales of 1982
Then happen two things that shake the industry to the core.
1983 came Commodore 64 and start world wide price war.
1984 happen Video Game industry crash by supersaturate market with computers and bad games.
This was down fall of several companies, Atari got sold, Jack Tramiel trow out Commodore, follow by Steven Jobs at Apple later...
also Clive Sinclair fell deep, Failure of QL, his electric car and other issue, Sinclair Research sold the the Spectrum range and "Sinclair" brand in 1986
Acorn computer survived by undergoing refinancing, working on RISK CPU
1986 Amstrad start with CPC and Sinclair computers, Dragon and Oric went insolvency
That Time frame 1980 to December 1982 was vital for survival of British computer industry.
Sinclair Research was unable produce sufficient ZX spectrums to gain momentum.
ironic Acorn had sufficient Electrons but too late.
in 1983 start Commodore 64 to dominated the low-end computer market, on those market were British could expands like European market.
(france was special case) Germany was in hand of Commodore international, millions C64 were sold here.
