I can only vaguely remember, as I haven't used this calc for years. But there's been some discussion of this elsewhere -- you may wish to do a little searching.
IIRC, when actually pressing digits (any keys?), the display briefly flashes with "22222222..." all the way across. I don't think there's any other manifestation, and when the key is released, the display goes back to normal.
There has been some discussion re: the cause. It did seem to me, way back when I was paying attention, that the only common thread appeared to be that afflicted calculators (all Spice models) had at least once been run on disposable (alkaline) batteries.
Someone will surely correct me if I'm off base.
I did find this - older - discussion. Apparently, the problem only occurs when there's one or more "2" in the display -- then "ghost" 2's start showing up with keypresses.
