I have scanned 11/34 field maintenance print sets.
They are at http://www.mainecoon.com/classiccmp/
And if I am not mistaken the MOS memory is there too.
AFAIK is MS11 correct, just the suffix letter makes
all the difference (core, 11/44 MOS, etc.)
MS11-xx is alway semiconductor memory of different capacities and speed as
specified by the last two caracters (to the best of my knowledge...)
MM11-xx are the true core memories with the ferrite cores.
(Wanna see a MM11-YP, 32k x 18 core-stack? Then bump the cofee-machine)
several years after Mos memory became available people were still talking
about core if they just meant the mainstorage or R/W-Memory, regardless of
the technology it was built with.
gd luck,

Heh heh, on what frequency is it radiating?
Do you remember the little proggys that would make a pdp produce sound on
an AM-receiver not tuned to any station?

if it is 128kx18, then it is a MS11-LD, and has an integrated parity
controller. I should have the maintenancemanual somwhere if it of use to
anyone. I will sent a free copy to aomeone who likes to convert it to .pdf
file to be put on-line. (Will have to dig it from the garage, however)
