Model no. 724
Part number 725-3770* (ANSI)
725-3771* (ISO)
FCC ID B4Y5K5724 (1988)
Manufacturer Wang, Alps Electric
Layouts Modified ANSI or ISO
Keyswitches Alps SKCL/SKCM series
Keycaps Cylindrical dye sublimated

725-3770 and 725-3771 are Wang keyboards that use Alps SKCL/SKCM series switches. These keyboards are described as "Model 724" on the rear label and were shipped with the Wang PC-280, a desktop IBM PC clone.[1]

It would appear that 725-3770 is used for US keyboards, and 725-3771 for European keyboards. This keyboard has an adjustable clicker. The large feet are adjustable in three positions by pulling outward. The keycaps are dye sub and double dye sub. There are two LED's on the very right and left between the keys help/esc and scroll lock/cancel. It appears the three increments at the top of the case above and below the function row were designed to hold note strips/ slides.
