Tektronix 2465B - Teardown

I went about replacing the leaky caps on the main board and cleaning up the damage from the corrosion. Unfortunately I got a bit careless when taking off the front panel and accidentally damaged the ribbon cable. I tried to repair the traces but didn't have much luck. 

I really just need to find a schematic to see if I can manually turn on the scope without the panel buttons (hopefully I just need to ground out a couple pins on the main board).
