Re: HP-41C: Module conflict Message #3 Posted by Vieira, Luiz C. (Brazil) on 4 July 2002, 5:41 p.m., in response to message #1 by Juergen Rodenkirchen
Hi;
check module's contacts. There are two contacts at the I/O assembly that are used to address the inserted modules. If there is a bad contact in any of them, you'll probably have problems (I am not sure if they will be like the ones you mentioned).
The only time I experienced this was when I tried plugging a MM in an HP41CV. You know, I rebuilt the babe believing it was a 41C, and it was a 41CV. After plugging the MM, the machine started a continuous, low-power tone. I removed the batteries and tried other doors. Only one accepted the module, and I am almost sure it was port 1. Without the module, I executed SIZE 000. Surprise: 00 REG 319. It was a 41CV!
This is not your case, I know, but I needed to tell the tale.
Cheers. And have a carefull look at the contacts.
