[GreenKeys] Teletype LB4/146 to LK II ARA (Transmitting Keyboard) Info RQ

[Nick England]

Unlike some machines, the 28 keyboard is not a self-contained add-on
assembly.

Someone had asked earlier about converting a KSR to an RO, and after
looking at the two in my basement I concluded it was possible, so
“probably” the reverse conversion is theoretically possible. You would have
to source a whole lot of pieces though. Maybe several hundreds of
individual parts…
Keyboard frame, keys, keylevers, code bars, transmitter, camshaft,
driveshaft, etc etc etc. maybe have to drill some more holes in the RO
base.

Except (with Teletype there is always an Except), the 28 compact does have
a M32 style electrical keyboard assembly with parallel output so you’d have
to add a distributor as in the 28 compact KSR. I can’t figure how you’d do
that on a conventional 28 base.

Far far better if you can find a 28KSR base/keyboard. Rara Avis in Oz I
imagine.
Good luck
