I used to work as a test engineer in the ICL plant in Kidsgrove where these machines were made. I automated the test suite by utilising the 25th line of the screen which you could both write to and read from. This enabled the machine to know where it was up to after a reboot say after formatting the Hard Disc. This greatly reduced the number of manual interventions required to test the machine and earned me an award from the ICL Suggestion Awards Scheme.

The technical authors at BRA01 were very keen on using the game that was started with the command Advent.something to "learn" about the RAIR $)

I have an ICL 8122/05 (Rair Black Box) with 8088 and a 10Mb Rodime Hard Disk, but haven''t tried to switch it on. Having removed all components, I powered on PSU alone which looks OK, but it''s providing only 10.3 volt instead of 12.0 volt. The HD has several labels referring to maintenance replacement of transistors, so under-volting PSU might be deliberate. Any info or software much appreciated.

I designed and manufactured the first 3000-4000 power supplies for this machine. The main feature of this power supply was that it was one of the first designs to use the new power MOSFET transistors that switched at high frequency and reduced the size and weight of the power supply.

I used to write instructions for modifying the ICL PC2 for re-sale as BT machines$ the ICL badges were literally prised off, and lovely new brown BT M22xx badges stuck on in their place!

I provided final line support within BT for the M2200 series - interfacing with ICL, and found ICL great to work with.

The PC2 series were also sold on to British Telecom through BT Merlin for them to resell. They were rebadged as the M2200 series. Having the the same numbers at the end as those shown on the first page. e.g. Model 15 =M2215, Model 26 = M2225 etc.
