There's a relatively simple mod Tandy made provision for in the T200 which
enables charging of NiCd batteries (and, iirc, modifies the low battery
indicator behaviour appropriately). It's documented in Appendix A-1 of the
T200 Service Manual and involves soldering two jumpers into through holes
provided for this purpose on the memory PCB (J301 and J302). They even made
provision for putting a screw in the battery door (and putting a red label on
it) to keep the user from replacing the NiCd batteries with alkalines after the
mod was done.
It would have been really nice if they had made the jumper through holes
accessible from the RAM/ROM compartment, but they're just far enough off to the
side and you have to take most of the machine apart to get to it. This isn't a
huge deal imho if you've taken electronics apart before, but the flex cable for
the screen can be a challenge if you haven't dealt with it before. The Service
Manual has detailed disassembly instructions on pages 2-1 through 2-4.
