The Zero series "Tenkeyless" has the same reduced footprint 87 key form as Majestouch models, but instead uses clicky Fukka white mechanical switches. N-key Rollover is standard functionality and this board has textured keycaps.
N-key Rollover allows multiple simultaneous key presses to be recognized by your computer. True N-key Rollover works only with the included PS/2 adapter. Using the USB connection will limit the N-key Rollover function to 6 keys at a time.
