Give that man a prize! It can load in 64 bits in a minimum of 420ns, and puts it into the Dacs and
control system.
The loading circuitry is surprsingly simple, and fast; but the board is very stupid-just follows
input intructions.
Big prob-newer cards don't have the port,MANY old cards that do don't support output (It was
expensive finding THAT out)
The port is lonely-it needs to be used!
I think the connector that runs the new flat-screen monitors may work too, or the Parallel port,
with input mods.
This version I'm doing now does NOT have any buffer on it, so timing is critical...maybe will add
later
if a real problem. (V and H blank) I want to do vector art! (test pix soon!)

BTW, i can't believe I asked what the baud rate of a parallel port was-it was late...
