you can find the cpu manuals for an 11/70. There are some
documentation on the KM11 in those, I seem to remember.
The original KM11 (I was given a pair _after_ making my homebrew
version..) consists of 2 boards -- IIRC W130 and W131. One contains the
switches and lamps, the other the driver transistors, etc. The latter
goes into the backplane slot and had an edge connector on the end to
connec to the former.
I've done a version based on Tony's design. I'm about to send the board
out to be fab'd. I've sized it so that it should be able to take the
original overlays too.
I'll be offering the PCB's (with schematic, BOM, etc) or PCB + parts +
docs for sale once I get the first boards back and debugged.
The PCBs will be nice with silk screen, solder mask and gold edge
fingers.
I think I got the schematics in the RK11-C printset, certainly it's
either there or in the 11/45 prints.

I'd be interested in a kit for my 11/05. Think the overlay is shown in
the Printset so I should be able to do my own ovelay when I find the
manuals.
Thought the KM-11 was also used on the LA180, been too many years to
guarantee that (it could have been the RX01, one or the other).
