HP-71B Rom Stuck in Port Message #1 Posted by Jeff Davis on 26 Nov 2011, 7:00 p.m. I have a 64K EPROM that is stuck in the port so tight I cannot get it out. What is the best method to remove the EPROM from the 71B.

Re: HP-71B Rom Stuck in Port Message #2 Posted by Raymond Del Tondo on 26 Nov 2011, 9:14 p.m., in response to message #1 by Jeff Davis If the module sits in port 1 or 2 (near the ON key) , you can try to push it out from behind, by removing the IL module (or the cover). You'll have to use a suitable tool, like an screw driver with isolated shaft. Be CAREFUL not to damage the PCB or any electronic parts on it! If the module sits in port 3 or 4, you may have to open the 71B, by removing the screws under the rubber feet and in the batt and card reader compartments. HTH Ray

Re: HP-71B Rom Stuck in Port Message #3 Posted by Patrice on 26 Nov 2011, 10:24 p.m., in response to message #1 by Jeff Davis I have a 71B with a very tight module. I am used to remove it by alternating moves to left and right while pulling and repeat tens of times. Patrice
