Thanks for confirming that my option of asking a local admin with internet access was the right way.

Still... had to load the tape on our office AIX machine (the only Unix box I had access to), then wire up a null modem cable to a PC, install Kermit on both ends, transfer all the floppy images, find an MS-DOS image writer, and finally copy the works on that stack of floppies.

Good times, sort of :)
