I recently picked up a Berzerk that was not working. When powered up I get 2 beeps and the LED flashes twice and goes out. According to the manual I need to look at the ram chips in 1E and 2E. I have replaced them with new chips. I have also replaced the transistor at Q2. The jumper is set in the right location. I am now to the gating chips at 2A, 3A and 6A. Is there any why to test them or should I just replace them?

Thanks
