Found the right torx t-15 screwdriver, €2,10.

This is what I found:

ROM and every other chip ok. No leaking capacitors in the motherboard.

Battery out, installed a new one. This is not relevant, since Classics can run with no battery.

Tried unplugging hard SCSI drive and floppy drive out from the motherboard and then booting.

Still the same.

Hmmmm, let me think.... :-/ :-/ :-/

BTW, if I unplug the RAM expansion card...should any jumper in the motherboard be changed? Which one?

Regards...
