This one: http://pdp-10.trailing-edge.com/tapes/bb-d867e-bm_tops20_v41_2020_instl.tap.bz2

The bad one is this one: http://www.bitsavers.org/bits/DEC/pdp10/magtape/dec_distribs/TOPS-20/BB-D867E-BM.tap.gz

Now that I have the basic TOPS-20 V4.1, I'm trying to find out how to add DECnet.  There are several tapes out there that claim to be DECnet V2.0 or V2.1.  But I have no idea what to do with them.

The DECnet-20 V2 manual has an installation chapter (chapter 10) but it starts with having the relevant files on disk, and offers no insight on how to get them from tape.  I tried each of the various tape images, some seem to be SIMH and some TPC format, but none of them are anything that DUMPER understands.  I thought that DUMPER is normally how one gets installation files off tape.  (DIR MTA0: doesn't show anything either.)

Any pointers?  Manuals?
