I also found that the "DECnet 2.1 SWS tape" has a whole bunch of neat
stuff on it.

I downloaded both images, but am only looking at BB-H240B-BM at the
moment.
This appears to be a KL distribution as it has a rather sizeable
directory for building an MCB imagine for a DN20.? A DN20 requires a
DTE, which the KS does not have.? You'd need something to DMA Unibus
to Unibus and I'm not sure whether that was ever a thing.? Sounds
like a great idea, if you ask me.
However, I don't think any of it will be useful.? Also, I can't quite
tell; it may be Phase III.? At least a document says as much.? Have a
look at VENTI2::H240B.LST, which is a listing of the DUMPER save sets
and VENTI2::DECNET.DOC, which is the initial documentation for the
release.
How would you like to proceed?? Skip this and look at the second
tape, which appears to be a 2020 based distribution?
