Well, I did something stupid today. My apple IIe was powered on and I removed the Disk ][ Interface Card..... Now the card will not allow the system to boot, green horizontal strips. Remove the card no problem. What would be fried on the card? I can't figure it out with my basic multi meter test.
Thanks
more than likely the MC3456P DTC.
