Yes! thank you! Nice, smart, and did good work despite the magateer, I
mean marketing dweeb.
I lost track of Harvey, Bob wen ont to start a company over in west
concord, can't recall the name, used some of his gear for projects in
the mid 80s.
I was designing a comms system in late 80s and heard Len Bosak had
started a company, had a couple of meetings with him, and went with hs
gear. Man those were fun post DEC projexcts.

KMC11 - Paul K cited the docs. It was a bit different from DMC CPU board
in both cycle time and in the use of ram versus prom.
Both boards/products used the 4bit Alu but I don't call that bit
slice, as the 2901 is more of a bit slice.
KMC and DMC are Harvard architecture based devices, as is the 11/60 CPU.
DMC and KMC benefited from the microcode work of Harvey Schlesinger,
Bob Rosenbaum, Richie Larry, and I think Clarise joined the team in
77. Can't recall her last name.
Patton? Harvey, Bob and Clarise joined the DECnet-RSX development team sometime in
77/78.
John.
DMC had (when I left the project and it had been
shipping for a year
or two) a 300NS cycle time, while the KMC had a 240NS cycle time
thanks to the instruction register I had suggested to remi as we were
thinking of a RAM based device because PROMS were a royal pain with 2
and 3 code changes a day. This change allowed the machine to begin to
access the next instruction as one was executing - there are no
interrupts in either board.
