This uncited claim was introduced 15 years ago, along
with the commit
comment "Hey, I saw drums (and core memory!) on PDP 11/45 hardware
running UNIX v6 (pre-BSD) in 1980 ... "
So, someone anonymous saw some once, somewhere, and promoted this to
"many sites."
Well, I can submit a correction, but does anyone remember /dev/drum? I
don't recall that in V6m or V7 Unix, I guess I could fire one of them up
and see....
Speaking of which I should make a copy of those disk packs for SIMH.
They are genned for a dual RL01 11/34 system and while I recall they
also worked on an 11/23 I don't have a pair of RL01's anymore (just an
RL02 I can re-jumper to read RL01 packs but NEVER WRITE THEM)
