The implementation that Mike Petry and I did at the University of
for our UNIVAC 1108 and 1100/40 was first written in UNIVAC assembly
was in the early 1980's, initially as a class project that turned into
a real "thing".
Later large parts were reimplemented in PLUS, a systems programming
UNIVAC / Sperry / UniSys created for the 1100 (and later, 2200) series
mainframes. That implementation later ran on 1100/80, 1100/70 and
series UniSys mainframes. TELNET, FTP and SMTP servers and various
and batch job submission services were supported.
