I can't tell for sure, but this auction may be for PDP8 core board.
board is 6 across in size.
From what I could find out K&T used PDP8 for NC controlled machines at
There is also this sort of board. The silkscreen shows a Microprocessor
section outlined with a 40 pin ceramic gold chip.
I am going to query the vendor to get a picture where you can read what
is on the can, or get the text on the can. Maybe the thing is a Harris
part, don't know.
Since the listing is for Giddings and Lewis, which is either a
subsidiary or competitor of K&T it may be another completely different
system. It looks like K&T, G&L and Cincinnati Millacron had a number of
legal runnins as there were several lawsuits in the google hits when
looking these boards up.
CM used an OEM Microdata 1600, and later 3 generations of their own 1600
derived designs before moving on to other newer microprocessor scale
parts. The CM 800, and 900 and one later are all 1600s, or near
relatives os such. The 900 uses 8K, 16K microdata manufactured core
boards, and also the Ampex / CDC 32k core board. I buy all those that
show up cheap on the usual auction site.
Here is the processor board:
