Some readers do this at all speeds. For example, any
Correct, the DSI NC2400 can be set up for different levels. It does require
a mechanical changeout for the punch, I think it's just a guide swap on the
reader. It's stepper feed but if you set it up for 2400 bps (default) and
let it run, tape motion is smooth and continuous.

Absolutely would be good to have. I would prefer a slow smooth pull through
the reader than slow and jerky or fast and smooth which are my current
options.

reading tapes as text and also as binary, 8/n/1 thinking that's going to
capture everything. I load into a hex editor, and if necessary convert to
