If you were using it in 1975-1976, it wasn't FTP as it exists today -
it would be the FTP implemented on top of the "old" ARPANET protocols
(sometimes referred to as "NCP", but I believe more properly referred to
as simply "Host-to-Host Protocol").

But that reminds me of a question I had while I was having lunch today ...
Was there ever an implementation of the old ARPANET protocols on a PDP-11
or VAX Unix? If it ever existed, I'd guess it would have had to have been
on top of Seventh Edition, but I can't recall ever seeing any drivers for
an ACC LH/DH or DEC IMP-11 on any incarnation of that platform. Berkeley
Unix added TCP/IP in 4.1a, but I don't remember if there had been any
ARPANET support (for the old protocol) before that.
