Re: 41C Memory Module 82106A Check / Test Message #2 Posted by Håkan Thörngren on 8 Oct 2010, 2:36 a.m., in response to message #1 by AlbertTocarLoseggs
If I am not mistaken, the service module can test the memory module. You will need either the real module (not common), or have an image of it loaded in some ROM emulation device.
The memory module loads itself in upper memory and becomes data memory by default, you can resize if you want to. I do not remember how many registers you should have (each module adds 64 registers), but if you find out, you can always write an RPN program put various numbers in it and see that they are recalled properly. Unfortunately, it is not easy to test with arbitrary bit patterns this way.
