    Default Amiga A500 sound

    Having problems with my A500 sound

    Can anyone check the output on Pins 30 & 31 of Paula and tell me the size of the signal (ie Pk-Pk voltage, DC component ect) ?

    I seem to have some sort of signal, but its small.

    Have a Paula on the way (9 !, worth a try) but want to trace the signal through the Amp circuit.

    New Paula fitted and no changed.

    Had a look at the signals coming into the chip and noticed that I was not getting any interrupts sent to it. There are three, one each from the CIA's and one from Fat Agnus. Reseated the CIA's and the interrupt appeared. Now I have sound and two working Paula chips
