Hi John
Thanks for the response. Yes photos would be very interesting.
If only one card is marked Arcturus then it's just possible you may have
something other than the main CPU box.
There would have been a TTY socket on the back of the CPU and I think it may
well have been 20mA loop as opposed to RS232.
Although it's approaching forty years ago I remember the system in its six
foot 19" rack along with the character generator sub rack. On thing did
standout. The character sub rack did not have a front panel and the boards
were quite widely spaced.
The CPU had a row of small toggle switches with white lamps above. To the
right was an illuminated on/off button.
Regards

A survivor. I only saw it once or twice but Jon Giver worked on one for
six
months.
I remember a gray rack mounted box with lamps and small toggle (Lemo type)
switches.
I have just the card cage, no lights, switches, etc. Maybe a power
supply and a blank front panel (19-inch).
Well John you have a real piece of UK computer
history. There can't have
been that many made. Is there any identifying marks or labels on the rack?
No, but the name "Arcturus" is on one of the PCBs. I'd better dig
it out this weekend and get some photos!
