KB-6151 is a family of keyboards from NTC.


The shape of the case resembles that of the IBM Model M. The top half of the case is beige plastic; the bottom of the case is a simple sheet metal cover, painted black with a water droplet texture. The switch mounting plate is screwed to the top half of the case from below.

All variants of the KB-6151 seem to have a bigass enter key, and a single-unit backspace key.

The XT/AT switch is on the right hand side (the left, as viewed from below).
