Keyboard–switch database Hi-Tek Corporation


Country US
Notes For the purposes of Keycombo, “Hi-Tek” covers Hi-Tek Corporation before and after its acquisition by NMB Technologies and in its later guise as the Hi-Tek keyboard division of NMB. This is to avoid splitting Series 725 up between more than one company, as presently a keyboard family is tied to a single OEM.
