Community Memory: Discussion List on the History of Cyberspace ______________________________________________________________________
There is a section on the LGP-30 in Bell & Newell's classic Computer Structures book and it appears in Wiek's 3rd Survey (1962.) It is a desk-size vacuum tube machine with magnetic drum main memory. The Computer Museum has one.
There were some drum memory descendants including the (transistor) LGP-29 and probably the (TTL) Litton ABS 1230 (which I have.) Apparently the line was bought out by CDC.
Possibly the story of Mel the programmer refers to the LGP-30 or another descendant. One of the early insights into chaos theory and the butterfly effect was obtained by a researcher (forget his name just now, sorry) doing weather simulations on a LGP-30. It was a popular departmental computer in its day.
I know a fellow who used the LGP-30 and LGP-29 and headed the user group for a while after it had gone to CDC. If there are specific questions I could ask him.
