How can you verify that the HP-85B is reading the RAM modules? Is there a memory test function?
Please let me know.

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.

Thanks for pointing me in the right direction. I had no idea there was a e-disc on the HP-85B!
