Notes: | |
1) This is the US layout | |
2) Early //e keyboard ROMs had ? LEFT ESC RIGHT SPACE replacing | |
the ESC DOWN UP LEFT RIGHT in the numeric keypad section of the | |
above diagram | |
3) If you want more details such as the influence of the Control and | |
CAPS LOCK keys or the DVORAK layout see pages 7-16 and 7-17 | |
of Jim Sather's Understanding the Apple IIe. | |
4) Unlike the ][ & ][+, the //e keyboard is completely passive with | |
the decoder chip located on the motherboard. | |
5) The +5v connection is to run the power light and the Open/Closed | |
Apple switches. | |
6) The SHIFT, CONTROL, CAPSLOCK and RESET switches simply ground the | |
appropriate pin of the connector (RESET via the CTRL line if the | |
jumpers are in the standard setting). |

The intersection of lines X3 and Y4 should actually be 'B' (at least on my board!)
