Please help! HP-55 odd behavior Message #1 Posted by Martin Pinckney on 6 June 2011, 8:48 p.m.
Thanks to Eric for responding, but I need more input from the Classics experts in the group.
Testing a newly-acquired HP-55. Timer mode seems to work fine. In program mode, I can enter keystrokes fine. But in run mode, no numeric input registers, and trying to run a simple program results in a flashing display.
Other keyboard functions (at least what I can try) seem to work. For example, although I cannot enter any numbers (the number keys just don't register on the display), I can, for instance press Sigma+ a few times, which leaves an integer in the display, then act on that integer. Correct results.
Any ideas?
