Bit: TYPE = KeyStation; -- for convenience

The Keyboard

keyboard: READONLY LONG POINTER TO READONLY KeyBits;

Positions in Keyboard array correspond to "keystations" common to all keyboards.

Higher-level software must associate characters with each keystation as appropriate.

Keystations are of five types:

1) Typing keys: (alphanumerics, punctuation, tab, CR, etc.)

2) Function Keys: Left, right, and top function groups

3) Mouse buttons

4) Keyset (Not on OIS keyboards)

5) Diagnostic (pseudo-keys for hardware diagnostic purposes)

Main typing array
