Holding down the Shift key doesn't change anything. The Mac in question is a IIci running System 7.5.5.

The card DOES work correctly if I connect a regular monitor to it, which is strange. It's as if the Pivot's weird sense codes are confusing it.

I really think I need the later ROM at this point, I'm convinced that it's the problem. And if it isn't, well it would be good to have a dump of the later version anyway.
