U8glib and SSD1306 I2C

I moved one of the 4.7k jumper resistors and pulled another 4.7k resistor off a discarded board and used that (much fun, used mag headset). In my previous message I posted how I hooked it up, not sure if that is correct as I read somewhere that there are 2 lines that should have power on them. I am not sure if the 'DC' pin should be pulled up or powered. I have found limited info besides the data sheet. The data sheet shows a 31 pin ribbon and mine seems to have a 30 pin ribbon.
Still going to play a bit for now (that's what it's all about) and maybe later grab another one.
Tnx, Mike..
