I have no idea. I'm using the exact part numbers from the Atari
service bulletin (reproduced in Gregg Woodcock's FAQ.) I believe (but I'm
reciting these from memory) that the part numbers are 1N754A and 1N756A.

Of course that's possible. I've tried numerous samples with the
same effect. Are the part numbers wrong in the FAQ? Have you gotten this
"upgrade" to work with those part numbers?
