the ASR33 TTY is Bell 103 at 300 baud?
"MODERN" modems that will do Bell 103, will often only do it at 300 baud.

... and if you take that Bell 103 modem off, and replace it with a V.18
modem, then the TDDs can connect at 45.45 baud.

The cheapest terminal that you can get is an obsolete PC.
Come to my neighborhood during the sidewalk/bulk pickup days!

TDDs are more expensive, and do not have a 24 x 80 screen.
They typically have a single line display, and sometimes an
adding machine width printer.

For what kind of applications would you consider that interface connected
to a timesharing system to be more usable than a personal computer,
or a 24 x 80 screen terminal?
