Hello Rossi, welcome to Classic Amiga. By the sounds of it, I am wondering if the TICK signal is failing from the PSU, this is a common fault due to age... but it could also be a bad CPU... I will have a read of the specs tonight to see if i can make anything from it
Hello Zetro I am Rossi I've heard that you know a lot of the Amiga ? I am trying to repair an Amiga A2000 . I have only 2,68 volts on pin 1 of the cpu ? and it is resetting constantly. I f it resets the 5,14 volts are for a second present. I followed the pin 1 and i see that it is going to the u105 and u 106 . And C300 . Where is the 5 volts comming from ? I can not see it in the schematics b2000cr I hope you can help me. greetings Rossi
