Help identifying (and finding docs for) Dataram core memory board

Hi all -- I have a pair of core memory boards (which look to be 8kilobytes + parity) in my Imlac, made by Dataram in the early 1970s (based on datecodes in the machine, I'd say late 1973, early 1974). I can find no documentation on them. They're labeled Imlac on the main PCB (P/N 01-12880-1), but Dataram on the core plane, and interestingly, this Blog post on Dataram's site: http://www.dataram.com/blog/?p=163 Has a very grainy picture of the assembly -- see the photo here: http://www.dataram.com/blog/wp-content/uploads/2012/08/40yrs_7.png So I believe the whole assembly (PCB + core plane) was actually made by Dataram. I have some high-res scans up at: https://plus.google.com/u/0/photos/117997069161125071032/albums/58762337385… (See the last two images in the album.) I'd love to find schematics for this, as it's the only part of the system I do not have documentation for (and it's going to need some repair, as it's got some fairly serious moisture damage -- some of the ICs are weathered enough that they're unreadable). I'm going to shoot a mail off to Dataram as well, but I figure my odds there are pretty low. Thanks as always, Josh
