    Does anyone know what the "I scrEEn" message indicates. That's what I get when I run this self-test. If I ignore that and type the test keys across the keyboard I end up with nothing but "620" and "pending" in small type. "amort" does not appear at all. ??

    its output are neither char function nor minimal polynomial. (in 50g , minimal poly is called minimum poly also.)
    is there any mathematical reference for PMINI ?

    The 10BII displaying partial digitals is a common problem with this unit. Apparently the glue that binds the ribbon cable from the board to the LCD breaks down over time and the LCD display suffers. This would account for the 0.01 display in the above post. The calculator is sending 0.00 to the screen but it isn’t getting there. I used the information here to repair mine: http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv021.cgi?read=245270
    I was a little perplexed by the instructions but I followed the advice and used a small blade to cut into where the ribbon cable attaches to the board. I only pierced the cable slightly and not very far. After my first attempt all but one of the digits worked. I returned to the ribbon cable and did it again in the general area of the bad digit and all numbers were fixed. Good luck!
