I found a copy of the schematic in the RK11-C printset. Mr. Duell's 
description does an excellent job of updating it. What is the equivalent 
of the DEC3009 transistor?

There was a discussion a while back about an equivalence chart for the 
DEC transistors. I can't seem to find the reference anymore. Not that I 
plan to make one from discretes, but it would be pretty easy to wire 
since it is such a repeatable pattern.

True, but if you have the manual that describes how to use the KM11, you 
usually have an image of the overlay.

It looks like the lamp board is a dual width, single height. It should 
not be difficult to take the overlay images from the manuals and 
photocopy them onto overhead transparencies.
