It looks like you already uploaded it to Manx: https://manx-docs.org/collections/antonio/dec/standards/el-00012-00-.pdf Looking though that led me to DEC STD 012-2 "Unified Numbering Code for Part Identifier Class Codes": https://manx-docs.org/collections/antonio/dec/standards/el-00012-02-.pdf which was exactly what I wanted. It's not the thing I remembered, but as DEC's official list, in some ways it's better (although it's so detailed it's kind of overkill :-)! > From: Vincent Slyngstad > the "Spare Parts List" links on this page are relevant: Volume II had a brief but early 'class code' list; I made good use of it. Thanks everone! Much appreciated! Noel

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: http://www.so-much-stuff.com/pdp8/repair/subst.php 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. 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. Vince

Noel 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.
