KB-6251 is a widely-sold family of slimline Alps keyboards from NTC (Nan Tan Computer Company). Current examples found use a bigass enter key and single-unit backspace key. The Alps switches are mounted onto a plastic or metal plate, giving this slimline model a very light weight. Variants with amber Omron B3G-S series switches or alps.tw Type T5 mounted into a metal plate were also made. Keycaps can be double-shot or pad-printed.
The XT/AT switch, located next to one of the flip-out feet, is unconventionally labelled as "80206/8088" instead of "A/X" (per the NTC KB-6151) or XT/AT. Newer models may also have "80206/8088" raised lettering on the bottom panel, but no switch.
The version with Windows keys is Unikey KWD-601.
June 6, 2020: Spotted a Zeos keyboard with Hi-Tek Series 725 black switches ("Space Invaders") on ebay. RT-101+ model number on bottom case label.
