I can't wait to buy one - I have a variety of C= machines, and it is
being designed to be *universal* - if your CBM has a 6-pin C2N-style
cassette port, it is supposed to work with your ROM-resident tape

I got the impression that's what you were going to do, but I didn't know
there was a specific program to do it. I do remember an article in an
old Compute! about reading ASCII BASIC tapes from an Apple into a PET -
there was an app provided in assembler to read the Apple format from a
C2N tape drive. You had to do a bit of work to tokenize the stream,
but that was the only hard part.

When a friend of mine and I needed to move data from the Apple to the C-64
years ago (the data file for an Infocom adventure), he had custom routines
to bit-bang the joystick port as 1200 baud serial - I made a cable to
tap into the user port on the C-64 and used its kernel routines. We both
did 6502 programming for a living, so it was trivial to port the receiver
app to the C= Would have been nice to have something Kermit-like back
in those days.

Either way, yes... Apple -> CBM is a bit tricky.
