HP-41CV and AME Port Extender Question

[knife31]

My mistake it is an Ext functions mod with the 2 memory mods. I know about the modules that cannot be collocated in a port. Just looking for the best way to configure the system including the switches.

I did have it configured as
HP-41:
port 1 Time mod,
port 2 PPC mod,
Port 3 AME,
Port 4 Card Reader

AME:
port 1 X-Functions,
Port 3 Ext IO mod,
Port 4 HP-IL Dev mod,
Port 5 Wand,
Port 7 HP-IL,

The HP-IL goes to an IL-printer and the IL-tape drive. I had it working OK until I disconnected everything, and brain stalled on my old setup. Screwed around with different combinations and just froze the calculator. Guess I will have to go back to the manual and start from scratch.
