... but i can measure the wiper and i get 0 to 5v on that side so it seems to be working.
The data sheet also says on page 4 that "Supply voltage for LCD (VDD - V0)" is typically 8.2V (doesn't say -8.2 but whatever).
I've not run across any ks0108 modules that didn't include the negative voltage (vee) signal, which most modules have on pin 18.
