Note: The 'position' notation here is consistent with that used in Binary Editor, 1-8 for example rather than 0-7.



- Mode 0:

- Turn QH off in terms of ROM presentation

- Essentially returns to stock, but keeps RAM monitoring active over full 4 bank range lower half so you can do 'stock' datalogging.



- Mode 1:

- EEC-IV, 56k/64k single bank, use edgecard-connector-mounted input as a 4-position switcher.

- Banks are rendered based on switch position input.

- 4 banks possible. Switch has 8 positions, but they repeat as you go from 1-4 to 5-8.



- Mode 2:

- EEC-IV with 8-positions via software.

- In this mode, external switch is ignored.

- Changing the position number will only affect which bank is rendered. R/W relative addressing etc remains the same.



- Mode 3:

- EEC-V with 2-bank 112/128k, 4-positions via software.

- Cannot use external switch.



- Mode 4:

- EEC-V with 4-bank 224k/256k 0189 arrangement.

- Case 4 with position 2 selected is the same as our base default case prior to switching introduction.



- Mode 5:

- EEC-IV with 4-position on switch (same as case 1), but it will track software-selected location (like Mode 2) when switch is in position zero (rotated fully clockwise).
