Ahh, the Apple Extended Keyboard II. Some argue it's the best keyboard ever made. I'm just here to tear it down. Some specs:

Model No. M0312 and M3501

Manufactured by Alps Electric or Mitsumi in Japan, Ireland, Mexico, or The United States

Plate-mount Alps cream dampened, Alps White, Alps Salmon, or Mitsumi White switches

The Caps Lock is a special locking switch - it stays down, just like a typewriter!

Two Apple Desktop Bus (ADB) Ports

108-key (ANSI) and 109-key (ISO) layouts

PBT Keycaps (well, except for the spacebar)
