Editing Zenith Supersport SX (section)

==Description==
The Supersport SX was introduced in 1989 and featured a keyboard with tactile [[Alps integrated dome]] switches with [[double-shot molding|double-shot]] [[keycap mount#Alps mount|Alps mount]] [[keycap]]s. Keycaps with two legend colours use locally coated [[keycap printing|pad printing]] for the additional colours.

The keyboard features [[Rollover, blocking and ghosting|n-key rollover]] using [[diode]]s. The keyboard [[PCB]] contains only the switches, diodes and [[lock key|lock]] [[LED]]s, with the controller itself on the motherboard. This makes the keyboard ideal for [[keyboard controller|controller]] replacement. The rear of the PCB bears Alps branding, suggesting that they manufactured the entire keyboard assembly.

The variant of the Alps integrated dome switch found in the Supersport SX has a gentle metallic sound and a positive tactile feel, around 65 cN. The tactility is crisp and precise.

The keyboard features an embedded [[numeric keypad]] with a [[pad lock]] key, giving it four LEDs instead of the usual three. The [[function keys]] stop at F10; F11 and F12 are only available on the [[Zenith ZA-180-89]] external numeric keypad.
