|Hi Sherri, my thoughts:- |
Are you sure they were created on a ibm or compatible pc?
Try them on the oldest/slowest pc you can find
Could they be HD (2 square holes) that have been written as DD?
if so, blank off the 'extra' hole with black tape.
Please advise back on progress.
As a matter of interest, where are you based? I am in Hammersmith, West London.
Good Luck - Keep us posted.
