The IBM PC was 25 years old yesterday.
Happy Birthday!
On the BBC the announcer introduced the story by telling us that IBM invented the PC 25 years ago and how Microsoft was so clever in inventing the PC operating system.
Not exactly as I remember it!
We had a Syrius PC in the office – and a great box it was. When it became obvious that the IBM PC was going to be big ,Syrius announced a ‘downgrade card’ that made the box PC compatable. We all nodded our heads – how true that was – and bought the card.
The Syrius, along with just about everything else in those days ran under the CP/M operating system from a company called Digital Research. That included the Apple II for which I think Apple could be justified in claiming to have invented the PC mass market. And Digital Research could have been said to have invented the Micro operating system.
You had run CP/M because Visicalc – the killer app of the time (they invented the spreadsheet) ran under CP/M. I went to the announcement of the IBM PC in New York and the presenter was downright sheepish about the PC DOS operating system they had provided. It is received wisdom that IBM provided the inferior PC DOS operating system because the authors of CP/M thought that they owned the market and could dictate terms to IBM. How little they knew about the marketing muscle of IBM in the 80s. Anyway we were assured that CP/M would be provided in a few months as an option, and PC DOS looked a bit lilke a stopgap.
Well respected comentators shook their heads and said that without CP/M the IBM PC would never fly. Then Lotus 123 was announced and suddenly CP/M didn’t seem such a big deal.
Digital research went on to develop a multi-tasking operating system which would run multiple PC DOS sessions and a graphical user interface. All to no avail. Whatever happened to Digital Research – I think they went bust.
