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.
The big 50s machines were mostly drum/disk based as core memory wasn't
available. See IBM 650, Zuse Z22, Ferranti Pegasus etc.
