===Hi-Tek Corporation acquisition===
NMB entered the keyboard market in 1983 when Nippon Miniature Bearing Co., Ltd. (now Minibea) purchased [[Hi-Tek Corporation]] and placed it under NMB.<ref name="US-DOC" /> At the time Hi-Tek just developed the [[Hi-Tek Series 725]], better known as "Space Invaders";<ref name="DMilo-F" /> these keyboards had just come to market at the point of the acquisition.<ref name="DMilo-T" /> The earliest [[NMB Hi-Tek First Generation keyboards]] do not bear NMB branding on the PCB. The membrane system used with [[NMB dome with slider]] is also thought to have been under development at Hi-Tek prior to the acquisition.<ref name="DMilo-T" />

Early Series 725 keyboards cite only '''Hi-Tek Corporation''', of Garden Grove California on the rear label.<ref name="kaineko2" /><ref name="rzwv" /> Later keyboards cite '''NMB Technologies Inc Hi Tek Keyboard Division'''', of Chatsworth, CA.<ref name="RT101" /> Keyboard PCB inscriptions suggest a separation between NMB and [[Hi-Tek|Hi-Tek Corporation]] by writing "NMB Hi-Tek Corporation" with the "NMB" logo enclosed in a separate box.<ref name="GH" /> A 1988 newspaper article refers to '''NMB Hi-Tek''' as part of NMB Technologies, with the parent company located in Chatsworth, CA.<ref name="LAT" /> 

NMB keyboards were produced in Thailand. Minebea established a manufacturing division, NMB Thai, Ltd. in Thailand in 1980.<ref name="history" /> Minebea's corporate history does not make any reference to the acquisition of Hi-Tek Corporation, nor do NMB themselves.
