their KA10 had a paging box, made by System[s]
Concepts
Speaking of which, here's a photo of the display panel from it:

The meter didn't show up well in that, and it's too cool to miss, so here:

is a shot of it.

That's brilliant. I love that meter, and now I kind of want to make
one of my very own.

I was looking at some photos on FB posted by a friend and ran across
Richard Greenblatt's oral history. It has some mentions of what the
PDP6's and PDP 10's were used for.

I've not had time to read other than to think these are perhaps
interesting if you guys didn't run across them. I think they may have
been used by the Project Mac folks. Perhaps posting this over on the
Multics thread might stir up some information if you want more. A lot
of the original guys are there. I'd be glad to do it if no-one else on
the thread here can do so.
Thanks for the interesting thread.
thanks

This document says MIT's Lab for Nuclear Sience was busy working with
their PDP-6 in early 1970. So that could not be the used machine the
DynaMod group got in late 1969. That is, if those dates are accurate.

The report mentions rearranging the core boxes (to be able to
interleave the two pairs of faster memories) in January 1970. The
conference date is March 1970, and it says they were "presently"
upgrading to a PDP-10, so maybe there were three on campus for a brief
time!
The table "Figure 4" is interesting: It shows they were able to do
scans 75.5%, 72.2% and 82.3% of the time in three months.
More time was lost due to Film Change, PEPR (Film scanner) trouble,
Magnetic Tape unit trouble (in increasing order) than due to the PDP-6
CPU; They must have gotten a GOOD one!!
I've converted my notes at http://www.ultimate.com/phil/pdp10/pdp6-serials.html
to HTML, and added some (but not all new info) from the current discussion.
The invoice dates come from a document about core memory royalties but
I didn't note a URL....
