Hardwarily it probably would -- most older async interfaces can handle
the timing specs of the 5-level machines. If they can be happy on a
20 mA loop, a KL11 or DL11 with current loop interface would serve.
(If it's a 60 mA loop, you'd be on your own -- unless you go via a
modem.)

The bigger problem is that your typical OS doesn't handle ASCII to
Baudot (Murray) code translation... Not that it would be hard to add,
and if you really wanted to do that, RSTS would be a good place
because the standard OS kit includes the terminal driver source.
