I'm working on a battery-bombed Laser 128 EX/2. Gate Array 1 (G/A1) is supposed to generate clocks off of the 14MHz crystal. The voltages and 14MHz crystal going into G/A1 are good, but none of the clocks are coming out. I fear that the chip is dead due to the battery leakage, but I'm hoping that someone knows something about how this chip wakes up that I'm totally missing. The two different reset lines and DMA line goes high, so from what I'm understanding, the chip should be functioning.
