Im very interested in the old Rediffusion network, dont know why lol.
Ive often seen the old redifusion boxes whilst doing installs in old council flats. Tried seeing if one worked one day with a customer who was also interested but nothing worked.
The old building in Plymouth still has the huge dish on the roof but its now a gym (work that one out Plymouth peeps!
). Seen most of the drains in Devonport, might open one up one day to have a peep!
