Once I had to take a PDP-11 accounting application from $EMPLOYER's NJ office to a customer in KC. It fit on a single RK, so I took two identical disks just in case. This was in the late 70s.

The next weekend, a colleague took the application on the same flight. On floppies. Floppy floppies. Lots and lots of them. It installed fine. Of course it took him all day and much of the following day. John Cowan http://vrici.lojban.org/~cowan cowan@ccil.org You cannot enter here. Go back to the abyss prepared for you! Go back!
