Wait? What was tricky about KMCs and DMCs? They used the same
algorithms, I had it down cold at the time.
Speaking of which, I have one copy of the KMC-11A Programmer's Guide if
anyone needs it or would like to scan it?

PS: I used ALGOLW on MTS in one of my ECE classes because we could
represent processor registers and operations using bit arrays/vectors
and boolean operations. Thus building working models of systems in
code.
