Pico P/S to send +5 into a line on the 2nd floppy drive wiring harness that the
STacy has. It powered up fine. I wound up not using it because I couldn't figure
out a way at that time to feed -20v to the original LCD screen.
Fast forward - I've got a handful of people telling me on Facebook that you can't
use just +5 volts alone. I already know that you have to provide a -12 volts to get
the serial port to work.
They are saying that without +12v fed into the ST's motherboard, you get no sound.
None. Nada. Zilch.
I honestly don't remember checking for sound back when I was experimenting with
+5v because I was concentrating so hard on getting the original LCD going.
So...does anyone know for sure if that's right or not?
Thanks much - just really curious.
