Arcturus Computer and display system.

[Rod Smallwood]

Hi All
         Whilst sitting on the plane on the way back from Newcastle
yesterday. It reminded me of a system I saw at Gatwick airport in the
early 1970's. I'm pretty sure it was run by a mini computer called an
'Arcturus'. I can clearly remember the grey rack mounted box with its
row of toggle switches and lamps. I was there to install a VDU
(sometimes referred to as a glass teletype). The big teletype they drove
it from made the whole place shake and the VDU I fitted of course did
not.  
 
It drove the departure / arrival TV monitors.  The way it generated the
characters was curious to say the least. It had a large number of
circuits which  generated parts of characters. One did a vertical bar,
another produced a whole circle whilst others output parts of a circle,
forty-five degree bars and so on. For each character cell the component
parts of the required character were selected summed and added to a TV
raster. Does anybody remember the Arcturus?
