Apple Product Collection@macgarden This came with Apple keyboards — they didn’t have their own manual, and everything you needed to know about them (how to plug them in, what the keys did) was covered in your computer’s manual.
A similar sheet came with Apple graphics cards (since expansion card installation is covered in your computer’s manual).
