SWTPC Computer Systems: Nothing beats experience This three-page advert, which is great for viewers in dark mode but which is not so good for the consumption of black printing ink, shows that Southwest Technical Products (Computers) Company Ltd was still alive and well into the era of the IBM PC. Rather than show any particular machine, it instead is demonstrating how much software is available - in particular how many specialist fields were covered by software running on SWTPC's machines, from insurance and building right through to the super-specialist field of microfilm retrieval. With configurations running from £4,000 to £40,000 - about [[4000|1982]] to [[40000|1982]] in [[now]] - it also claims that the company's S/09, which was based on the Motorola [!6809], was running benchmarks faster than a DEC PDP 11/70 minicomputer.
