Regarding the 1541 "save with replace" bug:  I recently (within the last
two weeks) posted a summary of the bug, who discovered it, how to never
have it, etc.  If necessary, I could consult my sources and repost.

Basically, IF you EVER use save-with-replace, you must EITHER:
(a) ALWAYS use drive number 0 in EVERY disk operation or 
(b) ALWAYS reset the drive before every save-with-replace.

You may also avoid the problem entirely by scratching and then saving.
Or you can get around the whole problem by writing a better wedge or a
little BASIC code that implements one of the above solutions.
