I did test both power supplies and voltages came in where they should have been. The composite video output is slightly different, when you turn the computer on there's a switch from black to a lesser black. Then you switch it off and there's a 1-2 second flash of white, then nothing.
There's no clicking from the floppy drive at all. Before it would spin endlessly but now it does nothing.
I'm 99% sure I've addressed everything with the 68k CPU.. I've tried four of them, all known good, I've seated them well, checked pins, checked continuity from pin leg to solder point underneath.. all comes up good. And the CPU gets warm.
I highly doubt at this point it's a chip issue, unless I got three bad Agnus' in a row, but I doubt that. So the daughterboard seems to be a next suspect. I've heard of RAM causing issues on post but not complete blackout like this.
Is there anything special/collectible about the Rev A boards? ie. is it worth going to extraordinary efforts to save them? Or would I be better to just buy one of those Rev 6 boards on ebay? Assuming of course it's not the daughterboard. I can't remember if the Rev 6 got rid of the WCS.
