NMB notebook keyboards

Although NMB was a major manufacturer of notebook keyboards, only one such type is known to have been documented on their website. This was model NOTE85A.


Model NOTE85A is a scissor switch keyboard with an integrated Light Point™ trackpoint. The Light Point is “based on technology and software license from IBM” [sic], and uses NMB’s own strain gauge technology. The datasheet is marked KB10/95 which suggests that it is from 1995 (although the PDF is from 1998) which may be why the illustration of the keyboard omits Windows and menu keys. The assembly contains a 0.5 mm aluminium backplate.
