Some HP-50G Questions

It definitely smells like some kind of weird firmware bug that never got fixed. It beeps at you as if it thinks you're pressing an invalid key, until you press some other key first and try again. IIRC, it doesn't happen every time, but occasionally. I'm not sure exactly what triggers it.

The Quick Start Guide mentions it (see below) but for the NO key; on reflection, this is where I've seen it happen, too, I think, not the YES key. Perhaps it affects both.

Quote:QSG: To clear all your memory from RAM, press and hold the ON, F1, and F6 keys simultaneously. Release F6, then F1, then ON. After a beep, the screen displays, Try to Recover Memory?, with YES or NO menu key options. Press the NO menu key. If nothing happens, push any key. After the beep, press the NO menu key.
