Good stuff! I'm glad to see you finally found a solution to the problem that also involved using some ducks-nuts hardware, the inverse of my current 9600 situation where only a stock video card or a busted Rage128 will work, but not the good 128 or the R7000ME. They were a fantastic card then and still what I consider to be a go-to upgrade for any G3 or early G4 era machine.
And for $25 shipped and in good time, you are laughing!
