Hi Netlanders,
Being in possession of a NON-switchable 80-track drive and often receiving data on 40-track drives, I have been giving some thought to the possiblilities of reading  40-track diskettes on 80-track drives using software tricks only.

Would somebody please correct me if I'm wrong, but would it not be possible to take a 40-track diskette, put it in an 80-track drive and using the XBIOS commands floprd and flopwr physically copy every OTHER track from the 40-track diskette to a standard 80-track diskette? This should then result in an 80-track diskette which only has data on the first 40-tracks, but which non-the-less should be able to be read quite normally by TOS? To make things a bit clearer here is a description of such a programm:

Copy track 0, side 0, drive A to track 0, side 0, drive B
Copy track 2, side 0, drive A to track 1, side 0, drive B
Copy track 4, side 0, drive A to track 2, side 0, drive B
Copy track 6, side 0, drive A to track 3, side 0, drive B

up to

Copy track 78, side 0, drive A to track 39, side 0, drive B

and then

Copy track 0, side 1, drive A to track 0, side 1, drive B
Copy track 2, side 1, drive A to track 1, side 1, drive B
Copy track 4, side 1, drive A to track 2, side 1, drive B
Copy track 6, side 1, drive A to track 3, side 1, drive B

up to

Copy track 78, side 1, drive A to track 39, side 1, drive B

If all this should work as I have described, obviously the next question is, has anyone out there already done such a program and if so would he or she be good enough to let me have it?

Thanx in advance /Walter
