British Micro Advert - December 1982

At first sight this is another obscure entry in the who/what/where department, however British Micro actually originated from more famous stock, founded as it was by John Marshall and Manas Heghoyan, both formerly of Nascom, and with the latter having bought Nascom in 1980 in order to rescue it.

Heghoyan had named his burgeoning empire The Hegotron Group, and the British Micro operation was based at Penfold Works in Watford, where Heghoyan's old PCB company had been based.

The company's Mimi 802 was a OS/M-running (fully CP/M compatible) Z80A-based micro with 64K memory and was first released in 1981^[1]. It was an update to the previous 801, which itself was designed by Gemini Micro^[2].

It was also said to be something of a "spiritual successor" to Intertec's seemingly-omnipresent SuperBrain micro^[3], and could directly read SuperBrain floppy disks.

Its overall design owes a debt to 1977's Commodore PET, with a similar off-white upper and black lower case construction and a monitor with a black bezel perched on the top, although the material of manufacture has moved on from the PET's steel to plastic.

Such was its design that the Mimi was even featured in a six-week-long display at the London and Glasgow Design Centres^[4].

It had integral 700K double-sided double-density floppy disk drives with a colour-coded 96-key keyboard and at 24lbs (a little over 10kg) in weight, was apparently "compact and light".

The advert also announced the availability of "Trojan", developed by software company Scifax.

This was one of a few program-generating languages around at the time, and was due for release as soon as the manual had been completed, which was thought to the the end of summer 1983.

The company's first home-grown software - Trojan Sales Ledger and Trojan Purchase Ledger - was released in May, with Nominal Ledger due a month later.

Trojan retailed for £250 (about £1,060 in 2024) and supplemented the existing Cashfix spreadsheet, released in April and which sold for £120 (about £510)^[5].

Trojan re-appeared a couple of years later on the IBM PC. Still developed by Scifax, which had since been taken over by media mega-corp BMG, the price of Trojan had doubled from its previous Mimi price of £250 to around £500.

MD of Scifax Howard Lock-Hooper said that "we've added more applications including Bought Ledger, Word Processing, Stock Control and Video-tape hire management. But the real reason for the price difference is that as part of BMG we feel we ought to give our partners a boost"^[6].

At £1,350, or around £5,740 in 2024 money, the Mimi 802 was firmly in the "professional" price bracket, not least as the orange- or green-screen monitor was an extra £132, or about £560 in 2024.

However, being from a UK manufacturer meant that it could have gone into the educational market, where the price was actually cheaper than Research Machine's 380Z. There were apparently 12 already installed in the University of Nottingham.

The Mimi 801 had already been released in Denmark, The Netherlands and France, and had even been shipped to South Africa, Greece and Iceland, with some orders from West Germany. The company was expecting to sell 2,500 units during 1982. That's small beer for a company like Commodore, but still a reasonable trade.

Mike Curtis concluded in his benchtest/review of the Mimi 801 in July 1982's Personal Computer World that

"It deserves to succeed even if I might query the wisdom of jumping in at the deep-end in what is simultaneously the most competitive section of the market and the one that could well show the greatest upheaval in the near future as new processors and operating systems challenge the Z80 and CP/M stranglehold. I liked the Mimi and it created a very favourable impression whilst sitting on my desk; it is a good-looking, well engineered, professional system^[7]".
