I have 30 small (6" dia) VAX tapes (Opus 6250) and 12 large (7" dia) VAX tapes (Scotch 700). I believe the small tapes are 600' x 1/2" and the large tapes are 700' x 1/2". I think they have all been written on once with data - no executible files. Tapes are free if you can pick them up in the Northend of Seattle. Mark Champion 206-524-0014 mark.champion(a)am.sony.com
