Didn't help, I'm afraid. That was how I confirmed the missing registers, though.

I figure this would be a simple fix with ZenROM or any of the other exotic development modules, but I just have Advantage and a couple HP application modules for my 41CX. Maybe some synthetic tricks could do it. I'm trying to figure out how to get a byte grabber assigned to a key other than LN, since I use programs with A-E local labels quite a bit.

Anyway, this is more for future reference if I get myself into another jam. I have a card reader on the way, so it'll simplify reloading important programs after a reset, at least.
