This apparently made a mish-mash of some of the RAM pages (my HEPAX RAM at 808 and 809 to be specific), effectively locking up the calc. I had to remove the batteries until MEMORY LOST. But then I managed to replug said HEPAX RAM and it locked up again. Next time, I did YMCPY from flash to ensure pages 808 and 809 were "sane". Then everything was fine.

This sounds like the result of a power glitch. Probably because the serial connector wire torqued the battery block. I have though about gluing the port cover with the serial port to the calc body, because I do the same thing fairly regularly.
