ACT/Apricot Advert - June 1984

Less than a year before Applied Computer Techniques, or ACT, changed its company name to that of its first computer - Apricot - comes this advert for its Xi model.

ACT, which had started out primarily as a time-sharing bureau in Birmingham, became more well known when it signed a deal in 1982 to sell Chuck Peddle's Victor 9000 in the UK, naming it the ACT Sirius 1.

In Europe, the Sirius had a head-start on IBM's PC - which it wasn't compatible with - and for a while outsold it.

By the autumn of 1983 ACT had developed its own machine - the Apricot, the name being a roughly-fitted "pretend-onym" derived from the company's full name - APplIed COmputer Techniques.

According to the advert at least, this became one of the best-selling 16-bit micros in the UK, and won several awards, including the Business Microcomputer of the Year.

The Xi - its name apparently deriving for the Roman numeral for ten (the size of its hard disk^[1]) with a trailing "i" because it sounds more technical, probably - was its follow-up micro.

It was essentially the same as the original Apricot, but with one of the floppies removed and replaced with an internal 3½" Winchester - making it the first micro in the world to use the latest small-format hard disk drives.

In keeping with the theme, the original Apricot had been the first micro outside Japan to use 3½" floppy disk drives^[2].

The company continued to produce sometimes highly innovative machines, including the first computer in the world to use Intel's 80486^[3].

However this history of constant innovation - and the expenditure it required - combined with its insistence on designing and manufacturing everything itself, led to various financial crises.

IBM clones and the growing Microsoft/Intel hegemony were also making life difficult for a radical outsider, and it was eventually bought out by Mitsubishi in 1990.

The combined operation nevertheless continued producing computers up until 1999^[4].
