41CX CAT 2 Scan Order → 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 3

Note: page 4 does not support standard ROM format, only specially crafted for page 4 ROM can be mapped to that page.
Examples: HP Diagnostic ROMs, Ángel Library4 ROM, etc.

Edit 1: fixed page modules:

• Page 4 → Diagnostic ROM / Library4 ROM / disabled Printer ROM (IL) / etc
• Page 5 → Time module (bank switching cannot be used for that page when the module is plugged-in) [C/CV]
• Page 6 → Printer ROM (bank switching cannot be used for that page when the module is plugged-in)
• Page 7 → HP-IL ROM (bank switching cannot be used for that page when the module is plugged-in)
  

Edit 2: Advantage module

This module is a 12K ROM that uses bank switching on the upper port.
To replicate this behavior with a ZEPROM/Clonix-D/etc, you need 16K of space and you must use a port linked-pages

Code:

           bank:  ___________ BANK 1 ___________  ___________ BANK 2 ___________
upper port page:  Advantage upper-page bank1 ROM  Advantage upper-page bank2 ROM
lower port page:  Advantage lower-page       ROM  Advantage lower-page       ROM
