In the 80s, running DOS 3.1 on an IBM Network, I was networking dual floppy PCs, and with testing, got through drive '!' '@' '#' '^' So I was able to use 26 floppies, 24 of them non local... It was all removed with the next release, 3.2, so I would make some bets about NT Networking and its NetBIOS roots.

I was inspired by the Dr Seuss, "On beyond Zebra."
