Disk ][ Interface Card Error

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

Looks like the issue is the SN74LS05N chip.
