OK now.
This is something I found on the Xilinx FPGA.
Am I over hoping this? Or is this as "easy" as it seems?

I've got to do abit more tracing for the FPGA yet. But it seems in the circuit, that my FPGA is after the SED1335; as my VS HS and VCLK all seem to go into the FPGA. I've got 2 of these boards and maybe I should pull one apart and "turn" everything around.
But, back to reality.
The only signals I need to worry about finding
into the SED1335 are...
INTERFACE................-->...................SED1335
........................................................VSS = -
........................................................VDD= +
........................................................RES = RESET
AF = AUTO FEED.......-->...................RD = READ SIGNAL/ENABLE CLOCK
INIT = INITIALIZE PRINTER.....-->.....WR = WRITE SIGNAL
STR = STROBE.......-->......................CS = CHIP SELECT
SLCT = SELECT.......-->.....................A0 = DATA TYPE SELECT
D0-7 = DATA 0-7.......-->...................D0-7 = DATA BUS 0-7
and out of the SED1335 are...
XD0-3 = X DRIVER DATA.......-->........VID0-3 = VIDEO DATA 0-3
XSCL = X DRIVER SHIFT CLOCK..-->..VCLK = VIDEO CLOCK
LP = LATCH PULSE.......-->.................HS = HORIZONTAL SYNC
YD = SCAN START PULSE.......-->.......VS = VERTICAL SYNC
Is there anything I'm missing?
Thanks for the help,
