After plowing through the archives, I have found that the problem is 100% consistent with the articles that posed the possibility that the memory chips need some sort of warmup (i.e. pre-charging or something) before they become stable.
Originally, when I first got this, I had the battery pack in and out many times for varying amounts of time. Whenever I found a problem, I might for instance, remove the battery to check (clean) the contacts. Of course, this would reset my problem.
After reading these articles, I let the calc sit for 15 or so minutes. NO PROBLEM ever again. I would then remove the battery pack for a period of time and THE PROBLEM RETURNED. Let it sit for 15 or so minutes and the problem went away again.
When I say it went away, I have eliminated the possibility of intermittent problem by performing numerous resets and running of programs and checking register data.
I can find no errors ever after the calculator has had the battery connected for 15 or so minutes.
I DO find this a bizarre behavior though.
