- The A4000 uses a different system from the A1200 for it's keyboard
- reset. There is no reset line from the keyboard to the motherboard (the
- system is (I assume) the same as the A2000 / A3000). Therefore it is
- impractical to use the line from the MPU, which is inside the keyboard.

- I connected my reset button to pin 128 on the expansion connector, which
- is /KBRESET according to the manual, and this works fine everytime (and
- bypasses that annoying delay).
-
- I'm not dure about the A4000, but the best idea is to check the pinouts
- for the Zorro III or CPU connectors for a pin with such a label.
