SwitchesAlps SKCM Orange or Salmon mechanical switches in M0115 variants, identified by Deskthority.Mechanical Alps switches; Deskthority's exact-model inspection documents tactile SKCM Orange and Salmon production variants and a mechanically locking SKCL Caps Lock switch. Switch variants and language layouts are not separate hardware generations.
Key travel–Exact-model key travel and actuation force are not published in the recovered maker documents and remain omitted.
Keycaps–Deskthority documents dye-sublimated PBT keycaps with an ABS space bar; these material identifications come from specialist inspection, not Apple's product sheet. The legends use Apple's bottom-left italic layout.
LayoutsApple's July 1987 product sheet lists 105 keys, including a numeric pad, 15 function keys, six editing keys and inverted-T arrows.Apple's March 1987 product sheet lists 81 keys, including the numeric pad and four cursor-control keys. The pictured US M0116 has a large Return key, Control to the left of A and Caps Lock at the lower-left corner. The related international M0118 layout moves these keys; it is a language-layout option, not a different generation.
Special keysF1–F15; the case marks F1–F4 for undo, cut, copy and paste, though Apple says these actions were not assigned by default.Escape, Control, Command, Option, locking Caps Lock and a separate power key. The four arrow keys sit in one row below the right Shift key; there is no F-key row. Apple's hardware reference explicitly distinguishes this keyboard from the larger Apple Extended Keyboard.
