dunno, the images are gone, but when I looked there was a ton of 74x logic series chips, which can be configured for anything

and for the time its quality isnt that much better than most commercial items, and since its almost all ttl (which has nothing to do with its output, I am using ttl 74x logic series to drive a low rez vga signal ... sorta its in the works) it wont effect much of anything in terms of rf (altho it may cause the puny power supply to pulse)

probably the only way to figure this out without having someone that knows is to hook up its output to a scope and see whats being sent
