Yes, Tim did a lot of excellent work on the Catweasel driver.
Unfortunately, there is something buggy in the RX02 reading and/or writing.
I tried reading multiple RX02 diskettes with Tim's software - and it
created images w/o reporting errors. However, when I attempted to re-create
RX02s from the images, it did so - but the newly created diskettes were NOT
readable by a real RX02.
I emailed Tim about this at the time, but IIRC, he didn't have an RX02
available to do testing against the "read thing". Tim asked me to collect
some debugging data - I did so, bot ended up dropping the ball when I my
non-hobby work load went crazy (it still is)...

Found an open source Catweasel driver for Linux, and the sources are
extremely helpful in deciphering its operation. Following a link from
the page, I tripped over:
http://www.tim-mann.org/catweasel.html
Most of the verbiage deals with its use in reading and writing TRS-80
formats, but buried in the docs was the news that it can read and write
RX02 formats. What non-DEC-compatible stuff out there can read
RX02's?
I'm sure a Catweasel can do it, but doubt that anyone has written the
necessary support software.
I just purchased one and hope to gain some experience writing drivers.
Unfortunately the API documentation is not very helpful. Tons of
nitpicky detail with absolutely no overview, theory of operation or
context in general. Not to fault the designer, but it's the kind of
thing that's easy to end up with when you know the subject so well
that the "big picture" is obvious to you, but need a reference for the
low-level details.
