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?

But they're probably not labeled; I don't recall that DEC shipped
this way.
If you let me know what tapes you're looking at, I can have a look
and give you some pointers or tips.
