In the early days of personal computers, there was something of a delay in the technology crossing the Atlantic, and when American computers did arrive in the UK, they tended to be expensive relative to local incomes. Thus for example the absence of Tandy left a niche for Sinclair's remarkable low-cost ZX80 and ZX81; the high price of the Apple II left a niche for the BBC micro to be adopted in British schools; the late arrival of the IBM PC meant the Commodore PET survived significantly longer in Europe than on its home shores.
However, this effect became weaker over time.
In September 1986, Compaq in the US launched the Deskpro 386, the first computer based on Intel's new 32-bit chip, and a very significant development for the industry as a whole, being the first time a non-IBM company established that sort of leadership within the IBM PC standard.
When did the first 386 PC go on sale in the UK, and how much did it cost?
