@Info-Seeker:

If you have tried cleaning the edge connector without success you can try reseating the socketed chips. There are 8-16 DRAM chips and 4 GAL chips an a PicassoII.

First discharge any static charges on your body by touching the metal case or power supply. (This may not be a problem where you live but it's better to be safe than sorry).

Using a small flat blade screw driver carefully pry each chip up a little ways on each end then press them back into the sockets.

You may also want to reseat your Buster or SuperBuster chip on the motherboard but you should use a PLCC extractor for SuperBuster. NOTE: Some A4000's may have SuperBuster soldered to the motherboard.

The next thing to check for is signs of Battery leakage on the motherboard. Also check for signs of cap leakage. (Either of which may need immediate attention!)

Also, if you have any other Zorro2 boards give them a try and see what happens. Finally, use a DMM or Voltmeter to check the +5 Volt supply on the motherboard. Good Luck!
