I've looked at many 26 pin 3.5" FDD pinouts in the last several days,
they all conform to the same standard, fortunately.
I tried the www below but get errors. I'll keep trying since there's
plenty of info there and it would be a pity to trash this 1400 LT just
to get the 720k FDDs out of it (which was my original intention) Thanks.

Google is your friend. Since the drive came from a 1400LT, why not go to
the source to verify the pinout?
