Chapter 1
News
Future historians may well regard 1984
as a turning point in the home computer market.
Infiltration of computers into British homes
reached new heights and the increasing sophistication
of software meant that users became less tolerant
of second-rate programs.
Many companies fell by the wayside
and Sir Clive Sinclair unveiled his most ambitious
hardware to date. Mike Johnston witnessed it all.
