Not C9 on the TI-86. It's C13! I remove C13, solder one end back to one 
connection on the board it came off of, but then solder two wires, one 
to the capacitor's free end and the other to the open connection on the 
board. Connect it to a switch, and you have a fast/slow switch.

My LED backlight will run your batteries down faster than normal, but it 
won't kill the batteries that fast. (unless built wrong)

I doubt it. Game Boy uses a slightly different version of the Z80 and it 
also has a different screen, memory, & has a waveform generator to 
create sound.

Not a battery charger, but an AC power supply. I suppose if used with 
the older SPinTerface port, it might charge low batteries when plugged 
in, but it then cuts non rechargable battery protection. Maybe a switch 
could be added.
