Thank you, Michael! You were absolutely right - it was faulty ANTIC. Now I have a smaller problem - system boots up just after plugging power cord on, switching on gives just more brightness and louder sound. It has to be a short circuit somewhere in power module. But I'm still happy to see boot screen and working system.

Hello, everyone! I have done my soldering job, but got only blank screen on boot. No key click is audible and BOB LEDs blink in about 5-10 Hz rhythm symultaneously. Everything else seems fine - powers, grounds, LEDs, connections etc. I tried Michael's osc advice and got such results: OSC and GTIA pin-28 look fine with nice sinus (pardon my poor equipment): But Sally's 37th leg is quite different and unstable: Sally's power seems to be OK. What else should I check? Is it specific for some kind of bug?
