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

I received a memory module that was open and I assume it doesn't work.

How can I make this module an I/O test module?

What type of glue do you recommend to seal it again?

I just wired a second 82106A PCB inside a standard memory module, but without B3 & B4 lines.

So when the module is plugged into port 2, the 'original module' takes its address from the port wiring; while the added PCB memory is allocated as if it was plugged into port 1; where the Service module is installed.

As you can see, no rocket science whatsoever... ;-)

All the best.
