Well, well, this is so 1980ties, the good old days when everything sold. The RAIR BC was a great idea which competed with color-screen but no graphic against the early PC graphic. The Display was just a line-display terminal. It was pretty slow but sold well in Germany, but nowhere else. Especially it was OEMed to Pitney Bowes who sold the machines under their own name. I believe over 2000 units were sold during a few years. This was a big number then. The machines died quickly from power supply problems and heat. I remember we even ran them in heat room for 72 hours to ensure that the machine survives.

At Rothmans cigarette company we sought to use RAIR computers to distribute our computer systems from a central mainframe to local operations in factories, warehouses and offices around the UK.

We took delivery of the first off the production line around 1981 and had only a few models for software development at first.

We found that the machines were not powerful enough to do the jobs we had planned for them and had to change from distributed micro computers from RAIR
to distributed midi computers from ICL and later IBM.

I used to service these very early PC''s. Had great fun doing so with a fantastic and dynamic management team. We all lived a good life out of it. The PC''s were multi-tasking units that supported dumb terminals. CPM and MPM were the OS''s supported. Mark Potts was the main driver for great venture and he also opened offices in SF (USA), Germany, France. Enjoyed training Guenter''s technician''s. It was way ahead of its time. Long live "The Black Box".
