See the comments from this guy named "Vigo" in 2009 in comparison to what he thought was an original Pong PCB:

1. Once the ball collides with the horizontal and vertical screen boundaries, it is stretched into the HBLANK and VBLANK area for 1 frame. Actually, that's exactly how I would expect it to behave when looking at the schematics. The simulations don't reflect that.
2. There is a space of 1 pixel between the right score display and the right paddle, when the paddle is on the same level as the score display. On both simulators, there is no space between the right paddle and score display, which looks kind of odd.
3. The graphics are mixed through resistors, which means that all elements are bright grey, and everything which overlaps with the ball is white.
4. I have to investigate it further, but it seems that on the original, the second paddle is displayed 4 more pixels to the right
It seems that his point 1 and 3 are accurately simulated then?
