Arcturus Computer and display system.

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? Rod Smallwood
