Thank you Ethan for a comprehensive answer.
It seems that I'm lucky my M7506 is -BF which is
512KW (any idea why the
field guide above lists it as 1MB?) and that my M8067 is -PL also 512KW.
So in total I think I will have 2MW :) if everything is functional that
is.
DEC typically referred to memory size in words, which are 16-bit on a
PDP-11, but many others count bytes. So 512kW is 1024kB.
I have a H9273, a 4x9 18bit CD backplane. No upgrade
done.
That's pretty easy to upgrade if you want to try it. I always used
wire-wrap wire, but soldered, for the extra four address lines.
