the new card is a TurboGX so i can get color graphics.

looks like the people who designed it left their names on the circuit board. i guess some of them are crossed out because they left the team?

aaand i get a black screen. that's odd.

hmm, maybe my adapter board (configured for H/V sync) will not work with this card that puts out CSYNC only.

no CSYNC comes out. checked it with a scope. OK, maybe the monitor sense pins being floating is a problem? i think it should still come up even with nothing (1152x900 66Hz).

that wasn't it either. no change.

quick sanity check with the old video card, and that still works OK.

@tubetime I'm not sure it helps, but can you actually put both cards in and get through the prom on the one that works, but only get the other in the OS?
