The IBM Lighted Program Function Keyboard (Model 48G9995) is a keypad specifically designed and made for the MICRO CADAM computer program. It was manufactured for IBM Japan and was primarily sold in Japan. The earliest known appearance is 1996.¹⁾

The case is made out of black plastic painted a beige color.

The switches used are Alps SKCL Yellow, with amber or green LED's. They are clipped into a painted bent steel plate which is secured to the top case by two screws. There are 32 keys arranged in a six-by-six grid with the corners missing.

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.

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.
