|HP48GX : faulty Port 2 ? any way to repair it ?|
Message #1 Posted by Antoine M. CouŽtte on 12 Jan 2012, 2:59 a.m.
Hello to all,
In the past few weeks, I have observed the following symptoms on an HP48GX which I have extensively used to develop my HP41 ASTRONAV Software through HrastProgrammer HP41X/Y/Z Emulator.
Whenever I plug into port 2 any type of Card (ROM Card or RAM MEMORY Cards), I get the following message "Warning INVALID CARD DATA".
In addition to this, whenever I plug into Port 2 a RAM Memory card 256K or bigger, all Ports from :2: to ... :33: show as being physically residing within the system, although for a 2MB Ramcard for example, no such Ports above :17: physically exist in the Calculator.
Trying to "PINIT", or even trying "Hard reset" through inserting a needle into the appropriate "foot hole" does not solve this situation at all.
Any clue here ? any (simple) way to fix it ?
Thanks for any information and/or help here.
