KBK update for Thursday, 31st October

The Computer History Museum scanned in for me (for a fee, $1/page) an assortment of Micro Switch Series KB literature (allegedly 400 DPI, but it is low resolution and out of focus). Still nothing on the keyboard reed switches, but there is a lot of detail on the other weird switches in the series, including the centipede and trombone types. The former are encoding switches, where the ASCII or scan codes are generated purely electrically without the need for a controller.
