Switches
Switches	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.	Deskthority documents Mitsumi rubber-over-membrane and SMK spring-over-membrane variants of model M0487.
Key travel
Key travel	Exact-model key travel and actuation force are not published in the recovered maker documents and remain omitted.	–
Keycaps
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.	–
Layouts
Layouts	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.	Apple's M0487 specification lists 81 keys, including an 18-key numeric keypad and four cursor keys.
Special keys
Special keys	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.	Apple explains that Caps Lock and Control moved relative to the preceding M0116, while the space bar became longer.
