Factory keymaps

Read off a PD-KB401B (HHKB Professional Classic, US layout) in factory condition, firmware A4.29. Two runs on separate USB sessions produced identical bytes, and a RESET_FACTORY_DEFAULTS afterwards reproduced them exactly.

Each layer is 128 bytes indexed by key number, keys 1 to 60, numbered from the bottom right. See protocol.md for the layout rules and protocol.md for the non-standard codes.

Reproduce these with hhkb_dump, and restore them with hhkb_reset --yes.

What the modes differ in

The three modes share almost everything. Taking HHK as the baseline:

  • Mac and Win replace Henkan and Muhenkan on the diamond keys with the GUI modifiers.
  • Mac alone has the media keys, Power on Fn+Esc, and Backspace rather than Delete on the top right key.
  • Mac and Win both have Caps Lock on Fn+Tab and the keypad codes on the Fn layer; HHK has neither.

Media keys, Power and Caps Lock being Mac-only matches the Fn key table in the manual, which marks them supported in the Mac column only.

The Mac Fn differences minus the media keys (27–30), Num Lock (32) and Power (60). The keypad codes and Caps Lock are present in Win too.

Where an Fn layer shows a plain letter

Positions where the Fn layer repeats the base keycode are unassigned: pressing Fn with that key just types the letter. That is the keyboard's documented behaviour, not a gap in the dump.
