Sorry, I meant to add that it's quite apparent
that the
Williams-Kilburn tube wasn't as such used in the Whirlwind, but the
M.I.T. Electrostatic Storage Tube was based on a similar principle,
even though the implementation was very different. You are correct,
and I should have checked more than one source. :-)
At least up through the 70's, Williams-tube type storage was still
undergoing development in the form of EBAM (electron beam addressed
memory).
Was EBAM ever commercially deployed? I remember seeing a rack of
them sitting in the hallway at ADL at CDC Arden Hills in the mid-70s
and being told that the project was no longer a hot item.
cf. IEEE "Computer", February 1975: "The Development of an
Experimental Electron Beam-Addressed Memory Module", John Kelly,
SRI. (Available online via IEEE CS subscribers).
Does anyone have such a device in their collection? CHM maybe?
