HP-41C service module question

RE: HP-41C service module question
Hi all,

The wiring I used for the ET-11967 replica was not exactly like the one used for the Double X-MEM.

I left the B3 & B4 lines without connection in the piggy-backed 82106A PCB, thus ensuring that it will always be allocated into port #1 regardless the physical port it is connected to.

Apart form this it's just a point-to-point wiring.

Hope this helps.

Diego.
