Future-proof multi-user CP/M system

Here's an early advert from Bromley Computer Consultancy - trading as Bromcom - for its Superstar CP/M-based multi-user system, which would be around until at least the summer of the following year.

Based on the S-100 bus, the SuperStar was one of several multi-user systems around at the time where the approach was for the "server" to host an entire computer per user as a plug-in card, accessed by a connected terminal.

This approach - which Bromcom called its "private processor" architecture - meant there was no service degredation as additional users were added, except perhaps for the few times that shared resources - the expensive things like printers and disk storage - were used.

It also meant that different users could run different processors, with a choice of 8-bit - probably Z80 - and 16-bit, possibly 8088, running "intermixed".

The downside with such a system was that initial prices were quite steep, with a two-user system with 10MB disk storage starting at £4,927 + VAT, which is around [[5666|1983]] in [[now]].

However, additional users were in the region of £1,000 ([[1000|1983]]) - which included the CPU card and a terminal - and so it did get progressively cheaper as more users were added.

At the time, [#IBM PC|IBM's PC] had only just been officially launched in the UK, with its entry-level model retailing for £2,080 + VAT and the minimum "business" system costing £3,442 plus VAT - that's around [[4000|1983]] in [[now]].
