9046xN random access write-only memory

Posted on Sunday, February 27th, 2011 in idle by Ian

MichaelZ tipped us to the 9046 x N Random Access, Write Only Memory:

About 1974, Signetics bought a two-page, full-color spread in the April issue of ELECTRONICS Magazine, and published the WOM data sheet, as a (rather expensive) April Fool’s Joke. This version of the WOM data sheet shows the various features of Signetics’ Model 25120 “fully-encoded, 9046 x N Random Access, Write Only Memory”. This advertisement has been saved, and greatly prized by engineers, for many years. We recently found a copy of this data sheet, in very good shape except for where it had been punched for a 3-ring binder.

Direct PDF download.

Thanks McZ!

    Thanks, I added a direct download link to the PDF version, the image isn’t very clear but there are pages of interesting text too :)

    @Ian, Thanks for the link. I’ve seen reproductions of this data sheet before. Bur unfortunately like all reproductions I’ve seen in the past, the .pdf at the link destination you provide isn’t good enough to produce a print quality copy. Oh well… Thanks anyway :-)
