+ | A daughterboard with 18 chip sockets is connected to the main PCB via a ribbon cable. It is mounted with two steel brackets. | ||
+ | |||
+ | The keyboard has an internal power supply that accepts 100-120v AC and 200-240v AC at 50-60hz. | ||
+ | |||
+ | The main controller is a Mitsubishi M50734FP in the 72-pin configuration. The EPROM is an STM27C256B. | ||

==Keycaps== | ==Keycaps== | ||
+ | The keycaps are doubleshot ABS, with one shot being transparent plastic. The keycaps have flat tops and an LED window. A common occurrence seems to be that the keycaps will crack, especially in the windowed area. It is presumably due to stress caused by the transparent portion being the keycap mount. | ||
