Yep. We used it for both but discovered it tended to be better for our system as a /tmp
because we tried really hard to keep the 11/70 from swapping in those days.

Are you referring to the slick little ML11-A (I think it was an -A when I
installed it at NY Telephone on
West Street, next to the World Trade Center...
I seem to remember it being used as an RS04 (or similar) fixed head disk replacement for
swap -- but
it could've been used for temp.
Funny seeing a fault light on a Massbus controller'd box of mostly MK11 memory.
IIRC it had write-lock as well.
Neat idea and I wish someone would come up with a really large SSD with a writelock for
archival storage
of my stuff. No head crashes and if I could disable the possibility of accidental
writing...
