HP-48GX RAM Card Problem

[calc_freak]

This problem just happened to my backup 48GX today with my HP 128KB card. Here is what I did to "fix" it:

First I checked the battery - 3.055 V, just fine. Left the battery out for a bit, maybe 10 minutes, put it back, ran PINIT, no change.

Next, I took the battery out again for about 30 minutes, cleaned the contacts on the card, put it back, ran PINIT, no change.

Got irritated and took the card out/re-inserted it a couple times while the calculator was powered on - no change.

Last thing I did was to take the HP 1MB card out of slot 2 (card was working fine), put the 128KB card in slot 2, tried PINIT, powered off and back on a few times - all of a sudden, no error message present anymore.

Put the cards back where they belong (128K in slot 1, 1MB in slot 2). No error message, and no data on the 128KB card. No problem, merged the 128KB card with main memory, copied the Meta Kernel over, and now it runs just fine. I hope this helps others with the same issue.
