Yet another oddity discovered today: it would
seem that the rotating magnetic
fixed-head disk in the Burroughs L-2000/3000/4000/5000 machines wasn't for
secondary storage (as I'd assumed), it was the primary store in place of the
core typically found in systems of the time. I bet there can't be many
machines around which had rotating store as the primary memory.
Not at all uncommon during the 1950's. (e.g. LGP-30)
Hmm, I stand corrected :) The big 50's and 60's machines this side of the pond
always seemed to come with core as the main memory; drum stores weren't
uncommon, but only as 'off-line' storage. Even the smaller desk-sized stuff
(BCL Susie etc.) were as far as I'm aware [1] core machines.
[1] We've got a couple to pick up at some point, both with drums - but without
getting hold of the hardware and manuals knowledge about BCL equipment is
pretty thin on the ground!
