KBK update for Tuesday, 27th October

A magazine article for Cherry’s then-new “gold-crosspoint series” of switches has turned up in a 1968 issue of Electronics magazine, scanned by Bitsavers. This article confirms that S31 Series was used in Hewlett-Packard’s 9100A programmable scientific calculator. By naming HP as a Cherry customer, this leads some weight to the suggestion that all of the “mousetrap” switches in HP equipment were supplied by Cherry. See the new Cherry Series S31 page for details.
