41CL Update stops with * in display

[Monte Dalrymple]

USB can only supply 5V, so you're already at a disadvantage. If you want, I can tell you exactly which location in YUPS to modify to eliminate the lowbat test. Just copy YUPS to RAM, modify, and run the RAM version to live dangerously. The source code is on the CL website, so anybody can figure it out. The LLD? instruction only appears once, in a subroutine that is common to all the functions that check for lowbat.
