Dexter rev3 progress

I made some progress on the layout for Dexter rev3.  I added a small 74LS244 IC to control whether VSYNC and CSYNC from the LM1881 make it to the 24-pin connector on the bottom of the board.  This is so that Star Rider can receive these signals but LD-V1000/PR-7820 games will not.

I also tried to pack in the resistors to reduce the board size.  Once I add all of the new components that I want, I will probably start routing.  I also am seriously considering reducing the IC size of the MAX222 and LED driver ICs in the interest of shrinking the board size some more.
