KBK update for Friday, 22nd January

Magazine trawling has turned up a short article on a Cherry keyboard kit that used their magnetic-separation reed switches. The article briefly details how these keyboards are designed to be wire wrapped during prototyping; this was likely to have slightly pre-dated the introduction of LSI encoders and external encoding PROMs.

A new SMK JM-0400 page now exists to collect up any fragments of information that turns up about SMK’s interchangeable low-profile switch series. There is also a “stub” page for SMK JM-0200, which is some kind of unidentified keyboard switch, which could be anything from their tall reed switches to a short-travel keypad button. An advertisement mentioning “JM 0404” lists it alongside “JJ0019”; JJ-0019 or J-J0019 is some other unidentified series of keyboard switch or switch component.
