“There were no design conventions for the earliest home computers, no rules for how they’d look,” says Alex Wiltshire, author of Home Computers, a new book that explores the rapidly changing face of the household machine between its birth in the 1970s and the 1990s.

A world away from the devices used today, the computers in the book illustrate the rapid march of technology.

Home Computers is published on 16 April by Thames & Hudson (£24.95)
