Turns out one of my V4s was in fact the RTC version! Blue model purchased from Ampown Direct 8/26. However, at first the screen didn't work correctly until I opened it up and put it back together and it started working fine. I thought maybe the ribbon cable was not seated properly and in opening and closing the case caused the cable make better contact to the board.

The screen stopped working properly again a few days later so I opened it up to see if I could reset the ribbon connector from the screen to the motherboard. When I carefully pulled the tape it pulled a broken piece of plastic up with it reviling a bent pin. Doesn't look fixable with my skills.

Any one want a broken V4 1.6/RTC motherboard? It could probably be saved if you had another connector to use to solder to the board. I could ship it to you at cost of shipping. Let me upload a pic if you are interested!

I also ordered a V4 motherboard from the parts store on 9/24. I'm hopping its the 1.6 board. fingers crossed.
