So, DEC part numbers (xx-yyyyy-zz) have a system where the 'xx' says what
_kind_ of part it is; e.g. bootstrap PROMs are all 23-xxxxx-yy. I seem to
recall reading at some point something which listed all the xx- codes, and
what they meant - but now I can't find it. A Web search didn't turn it up, and
it's not in the 1974 'engineering handbook'?
Does anyone recall seeing it, and if so, where?
Obviously, I could look through a bunch of print sets, and reconstruct it
(e.g. 90- seems to mean mounting hardware - nuts and bolts, etc) but I'd
rather not put the time and energy into reconstructing the wheel, unless
there's no other way.

I thought that there was something at the beginning of the Options and
Modules List (aka the "Dick best List") but seemingly not.
It was (iirc) described in DEC STD 012 (the part numbering standard) but
I don't seem to have that one handy. If you can find it it should
contain everything you want. I do have (or did have) a DEC STDs CD at
one point, but my copy of that seems to be missing DEC STD 012. There
are plenty of DEC STD docs that would rate considerably higher on the
"confidential" scale than this one and they are freely available, so
I've no idea why this one might be missing.

Maybe here?

I knew I had the documents, but I couldn't figure out where I originally
got them. (They seem to have been converted from TIFF, so maybe highgate?)
Anyway, the "Spare Parts List" links on this page are relevant:

These documents are dated July and Sept. 1970, so you may well want to
do that work anyway, to get a handle on the newer part numbers.

New subject: DEC backplane power connectors
Are the power connectors on the DEC PDP-11 backplanes (e.g. DD11-DF 15pin and 6pin) Molex
or other?
Are they still commonly available?

They are called Commercial Mate-n-lok. Company is called TE-Connectivity
nowadays.
Later on DEC used Universal Mate-n-lok. For example in the VAX-11/750.

Thanks much. I think I found the mating plugs I need on the te.com site and digikey has
them.

Could you post the part numbers?
Thanks.

Well, they vary for what you may need of course, but in my case, I wanted to connect to
existing
DD11-DF female shell/male pin 15 and 6 contact connectors.
Searching the te.com site, there are some similar parts, but the ones which look correct
are:
Commercial MATE-N-LOK-S, 1-171196-0 (digikey A106239-ND), 6-pin
CMNL PLUG HSG P/M NATL, 1-480323-0 (digikey A1427-ND), 15-pin
There are a number of pin options for these, but I picked: 170121-1 (digikey A122316-ND),
tin, 14-20 AWG
Once the parts arrive, I will confirm if I chose wisely...
