This is number seven I am attempting to fix today. the card looks differnt from any other card I have seen. Does this one accept positive sync,reason I'm asking is that is what it is being tested on and cant stop it from vertically rolling .take a look at the pics and tell me what you think. first pic is a normal x/y card and the second pic is the oddball one.

Ken Layton put this together, it should answer your question.

Not seeing what is "oddball" about it, but the other card determines whether it accepts positive-only, negative-only, or either...

if you closley at it, its screened in black instead of white and has different larger diodes by the bottom, havent noticed any other differences but thought it might need to be paired with a certain 4600 version.
