I look forward to taking a stab at this.
I suspect there are a number of people who'd be interested in MASSBUS storage
devices (e.g. me - suddenly all those RH11's I've got are no longer boat-
anchors :-). We should try and organize an group build, to share the load.
Anyone else interested?
Oh, one detail I didn't look at: what's the physical interface this uses?
Hopefully three of the Berg/DuPont connectors (i.e. what's on the RHxx
boards, with flat cables going to the adapter to the standard MASSBUS
connector, a device rejoicing in the name 'Receptacle Housing Assembly'); the
original MASSBUS cables (along with the 'Receptacle Housing Assembly' are now
rare as hen's teeth). And there's also the MASSBUS termination...

(This is very good news, the chance of getting my 2020 running by year
2020 is now a lot bigger. Also, as I've stated elsewhere, thank you to
LCM and everyone involved!)

There are plenty of companies in the "prototype production" business; they will
make either blank printed circuit boards, or assembled boards, in small quantities. For
our purposes a group build probably counts as "small quantity". One I can think
of (and have used for blank PCBs) is PCB Pool.
Depending on the parts involved and the skill level of the consumers, it may be reasonable
to get blank boards and a parts bag and have the user assemble it -- or it may be better
to let professionals do the assembly.

I'm quite confident with a soldering iron when it comes to through hole
components. I haven't looked at the BOM for this project yet but I guess
there are surface mount components.
Perhaps an opportunity to learn.

It uses three 40-pin dual-row headers, so you can cable it to a real
Massbus connector (RHA), or you might be able to cable it directly to the
Berg headers of a DEC Massbus adapter.
