Subject: Does anyone actually have a KT11-B?
Date: Fri Sep 30 19:04:47 CDT 2016
the ones shown in the images show it to be (mostly) an
RK11-C.
...
I say "mostly" because there appear to be extra cards on the right hand
end; whether those are some sort of upgrade to the RK11-C, or whether
someone just stored spare Flip Chips out there, I have no idea.
So this mystery has been solved (sort of). According to some drawings I have,
there is apparently something called a "Double Buffer Disk Control" variant of
the RK11-C. I looked online, but there was nothing about it there, and the
RK11-C Engineering Drawings at BitSavers don't cover this variant. Does anyone
out there have one of these?

even made an inventory of it. What would I look for to know?
