[Simh] DECnet for TOPS-10

Fri Apr 19 21:08:30 EDT 2013

You need the DECnet tape that goes with the monitor version you're running.

http://pdp-10.trailing-edge.com/ is probably a better source, in that 
you can browse the tape contents.

TOPS-10 7.04 needs the 7.04 DECnet tape.
TOPS-20 4.1 needs the 4.1 DECnet tape.

You don't need DECnet Source tape (that's for the MCB - DN20 code for 
the KL).
The tapes with TSU in the description are autopatch tapes; you don't 
need them (at least to get started with.)

This communication may not represent my employer's views,
if any, on the matters discussed.
