Re: about HP41C memory module Message #2 Posted by Steve on 20 Dec 1999, 4:21 a.m., in response to message #1 by Iqbal The 82106A is a memory module for the HP-41C You can plug up to 4 of these into a 41C. A 41CV or a 41 CX already have the equivalent of 4 of these built in, so they're no use wuth these calculators. Each module is 64 registers (from memory) To see if they're working is not a trivial matter. Plugging these things in increaces the number of registers available. So the first thing to do is find out how many registers you have. Then plug in a module and see if you've got 64 more. The modules lose their contents almost immediatly on removal. Don't plug or unplug the modules while the calculator is turned on. Removing a module in certainn circumstances will lead to MEMORY LOST.
