Hi Tony
Did you say Data Dynamics? I certainly knew them. I used
to sell them LA36 print mechs.
Yes, almost certainly the same company. They sold several teleprinters
based on the Teletype Model 33. Same mechanics, but IMHO a nicer (all
metal) case and different electronics. I have one which is a normal
ASR33 typing unit, keyboard, and reader but in a case with bulbs to
illuminate the printout and electronics to give both RS232 and current
loop interfaces and a single-step button for the reader.
It was run by two old guys called Tindale and Stabler.
The factory was
in Hayes and I used to drive
there from the DEC office in Ealing via Bombay (sorry I mean Southall).
Ah, that Hayes, not the one just down the road from me across Keston Common.
