But no indication of where they came from (who wrote them).
I've dropped them in ftp://ftp.ultimate.com/pdp10/tops-10-deuna/

I've seen the (Don Provan?) TOPS-10 TCP/IP stack among TOPS-10 7.x
sources from KIKI (the dual KI), but *NOT* any of the userland code.
ISTR TCP connections were "assigned devices", and so persisted between
program invocations!!
