I wrote such a program, back in the days. It was very simple, calling
RWTS to read the disk sector by sector, filling memory, and then using
monitor routines to save it to tape. Repeat until done. Another program
did the opposite, writing a disk from the tape. I used it once, maybe
twice, saw that it (a) worked and (b) took forever, and that was that.
I thought about interpreting the VTOC (this was before ProDOS, of course)
to skip unused sectors but never got round to do it.
I also saved an Apple II program on 8-track tape, once.
