RT-100 series and RT-8200 series refer to a family of Hi-Tek Series 725 keyboards from NMB. The two different sets of model numbers appear to be the result of a new classification system introduced at NMB, that moved their mechanical keyboards into the 8000-range instead of numbering them by key count. This made way for a variety of other keyboard types to be unambiguously numbered. This page deals with the RT-8200 series and mechanical RT-100 series keyboards.

There are at least two designs: one styled after the IBM Model M, and one with a thinner, flatter case. Over its lifetime, numerous FCC IDs were used.

A PCB found in an RT-8251T lists the original model numbers as RT-101, RT-101+, RT-102, RT-102T and RT-103T.[1]
