Hand Held Products 71M/M eprom carrier question
Hi everyone;

I have this Hand Held Products 71M/M eprom carrier designed to go in the card reader compartment of the HP-71B. It currently holds a 32k EPROM (HN27256G-25) containing some fire insurance claim software; it came in an HP-71B that I bought a long time ago. This device has a 3-pin jumper pins close to the Vcc pin of the EPROM. Currently there is a jumper joining the two pins closest to pin 1 in the EPROM. Does anybody know the function of this jumper? I am planning on burning a 27C256 with more useful stuff.

carlos.
