This is a IBM 704 introduced by IBM in 1954. 1:16 scale model, hand made in mostly polystyrene.

@6502B Ours was a very grey 7094 (or as the insiders knew it - "709 T 4" with T for "transistor".)

I liked the rows of "sense switches". I had hear that somebody rigged up a bunch of (36) motorized "fingers" so that the sense switches could be flipped under remote control. Probably one of the earliest examples of computer porn.

And ours (UCLA) had oil-cooled memory which, of course, like all memory, leaked (but this memory leak had to be cleaned up with a soapy mop and bucket.)
