The KA-10 was always connected to the PDP-6 via shared memory as long as the
PDP-6 was in use (until the KA-10 and KL-10 were moved from the D. C. Power Lab
to Margaret Jacks Hall on the main quad). In the sources, references to
processor P2 mean the PDP-6, until it was demoted to P3 and the KA became P2,
as the KL became the primary processor.
Yes, the KA-10 used the BBN pager. We have it in Seattle.
The disk controller is irrelevant to which CPU(s) were in use.

Any pre-1974 WAITS.DMP will be KA/PDP-6 only. Pick up the blob file, convert
the octal dump to binary, and you're good to go.

That will be fun.
