Re: HP 71B - installing memory modules Message #6 Posted by Raymond Del Tondo on 7 Jan 2008, 7:30 p.m., in response to message #5 by Rob Lilley
Ok, so it's a CMT 32K RAM module.
From my experiences with these modules, they work 'plug_and_play'.
Since it doesn't seem to work as easily as it should with your unit,
you could try the following:
After a backup of your data, and _without_ the CMT module, perform a master reset on your HP-71.
This can be achieved by pressing and holding the ON key,
then pressing and releasing the '/' (Divide) key, then releasing the ON key.
INIT:1 should appear in the display. Press the '3' key on the num keypad, followed by ENDLINE.
'Memory Lost' will be displayed. Then turn the HP-71 OFF.
Insert the CMT module into the leftmost port (seen from front).
Turn the HP-71 ON. After a few seconds, the blinking cursor will appear.
Enter MEM. What is displayed ?
