Mac Plus probing video signal help

[gkmaia]

I am apparently with an issue on my Mac Plus video signal.

Lifted R30 to isolate pin #20 (Video out) of BMU2 from the analog board and everything else. Nothing is damping it... it is pretty much weak on it's own. Also did some logic probing on the BMU2. All Is and I/Os are pulsing apart from I14 as it is nodded to OE.

Anyone out there with one of this on the bench and could send me a scope plot of J8 pin1 or U2 pins 8,9 and 10?
