Re: Plz help with Catweasel programming , I/O Register meaning, Track reading

You should download and check the Linux Catweasel floppy drivers, 
provided by Michael Krause 
( ) . ...Not exactly 
what you need, but you'll get some ideas, I guess.

BTW, that DOS based 1541 reading tool should be pretty outdated anyway, 
and the Catweasel has evolved at least three generations since then 
(currently, they sell the MK4 ). Any ideas, why JS / Individual 
Computers don't publish the source code of their win32 drivers provided 
with the card?... I don't.
