Ouch, I just ordered a bunch of these.  Have had absolutely no problem with
4-bit, 8-bit and serial pic setups on Powertip and Optrex units in the past,
and figured that if these have a 44780 chip, they must be ok too.  Hope
somebody finds the solution.  Has anybody confirmed they do need -5v
contrast voltage?
