You're quite right Dave, but as it's missing, I was saving on the typing
:)
Jim.
Tony, I also have two scrap TDMS chassis (a 5 and a 6), which have
had the
polar relays, CRT's and valves removed, but they do still have the
transformers, switches and sockets. Do you need any spares, before
they get
cannabalised?
Jim.
IIRC one of those 'polar relays' is not- it's actually the QBF
message generating coder-a very clever little electromechanical device
with a "disc" memory. And that spiral timebase was something else -
very clever - more modern TDMS variants with linear displays were
never the same.....
