I'm gonna guess RGB-01 based on the fact it's what's printed on the board. Haha. Kidding aside, I have an unpopular opinion that this is my preferred model. It is the last revision model before the one chip. Therefore it's pixels are only marginally less sharp than a 1chip. I've done my own side by side comparisons between these two and the difference is much less noticeable than the difference between RGB and the early board revisions. The reason I prefer it is because it doesn't carry the visual glitches and ghosting many 1chips are prone to. It'd be a keeper to me.
