Hi, all, I'm looking for any/alldocumentation for the PDP-11/34A cache, the
KK11-A. (And no, it's not in the 11/34A print set!)

At least one document does exist, the KK11-A Cache Memory Technical Manual
(EK-KK11A-TM-001); this page references it:


but I can't find it online (well, someone's Flickr site has an image of one
page of it, but that's all).

The mention there of "cut the 'cache hit line' on the DD11-PK backplane" on
that web page (above) has me concerned! But in general I'd like to know more
about this board.
