Was reading the Wikipedia article on Drum memories:
https://en.wikipedia.org/wiki/Drum_memory#External_links
And came across this tidbit.
As late as 1980, PDP-11/45 machines using magnetic core main memory
and drums for swapping were still in use at many of the original UNIX
sites.
Any thoughts on what they are talking about? I could see running the
RS03/RS04 on a 11/45 with the dual Unibus configured so the RS03's talk
to memory directly instead of the Unibus, but that's not quite the same
as true drum memory.
Closest thing I remember was the DF32 on a pdp8 which could be addressed
by word as opposed to track/sector.
Thoughts?
