128k Ram modules for HP-85B Message #1 Posted by Jeff Davis on 21 May 2009, 6:33 p.m. How can you verify that the HP-85B is reading the RAM modules? Is there a memory test function? Please let me know.

Re: 128k Ram modules for HP-85B Message #2 Posted by Eric Smith on 22 May 2009, 2:54 a.m., in response to message #1 by Jeff Davis It acts as an "electronic disc", so you have to use the E-Disc commands (built into the 85B, optional for the 86 and 87) to access it. I don't know the details, but it should be covered in the manuals.
