The BBC nuke drama "edge of darkness" features the systime hq in Leeds.
I worked there briefly in 1982. Fantastic subsidised lunches in the factory canteen, robot delivery carts following magnetic stripes in the flooring, and a lisa workstation in the r&d department i played with.
The head of r&d John Bondi was Herman Bondi's son. (Herman was an Austrian-British mathematician and cosmologist of some note)
Happy days.
Though we didn't have the luxury of a terminal in the school - we sent our work of on coding sheets and got the results back for the next lesson.
We used CECIL (an assembly language designed for education) and in the second year BASIC.
This was the CSE stream BTW aka the stream for those expected to leave school at 16
