When I was in school (35 years ago) I had an IBM 1052

interfaced to an 8080. The issue with the 1052 was that the relays
were all 48v so finding drivers was interesting. ;-) It took me a bit
of fiddling with the timing to get it to print properly (at 134.5
baud). It sure beat the ASR/KSR-33s that most other folks were using
for their terminals just for the "cool" factor! TTFN - Guy
The mechanicals of the 735 and 1052 are basically the same. The 1052
has pin feed, extra switches and things to suit use as a computer
console, whereas the 73x are designed for word processing use. The one
I got came from such a WP system, though I've no idea where the rest of
that system got to. It was a "Kode" system (Calne, Wiltshire, UK) which
used paper tape.
