Description

Apple Desktop Bus Keyboard, A9M0330, 658-4081. This is the keyboard that came with the Apple IIGS. Complete keyboards are currently only available with purchase of an Apple IIGS here. They all started life looking like the second photo, but most now look like the next – SMK (Taiwan) on top and Alps (Japan) below).

While they look the same on the outside, there are two main differences that affect which key switch or key cap that you need. Pop off a keycap (not Caps Lock), if needed. Are the stems of your switches orange, salmon or white?

If your keyboard label say “Made in Japan”, it uses orange or salmon colored Alps switches. The keycaps are platinum colored top and bottom and longer keys use brown stabilizer bar clips. The 3 case screws always use a washer underneath the screw heads. The keyboard ROM may be socketed or soldered and the printing is facing the front of the keyboard. ROM may be 341-0232 or 341-0124. Key caps don’t really discolor, although the case, numeric keypad divider and space bar do.

If your keyboard label says “Made in Taiwan”, it uses white SMK switches. The keycaps are dark gray on the bottom and longer keys use white stabilizer bar clips. The 3 case screws may or may not use a washer under the screw heads. The socketed keyboard ROM, 341-0124 printing is facing the back of the keyboard. Key caps always discolor with rest of case.

The switches are not interchangeable between Alps and SMK. The SMK switches were only used in this keyboard whereas the Alps switches were used in several – see note at the bottom.

The key caps are available on this page, everything else is here.
