It is still a 'good to have' for those running real PDP-11 machines without
I/D support, like the 11/23 and 11.23+.
The TCP/IP stack Johnny has written works great on the machines (emulated
or real) that do support I/D space.
I would really like to have Johnny's TCP/IP stack on my 11/23+ but I
understand it is a big undertaking to modify
the stack to work on non-I/D space systems. DECnet works though but lacks
NTP-like utilities.

Neat! Is the rsx code or source code for the rtc
anywhere? It's less
necessary now that we have ntp from the tcp stack (thank you bqt) but it
would still be cool
