Hi
Happy Christmas!
While the kids are watching an xmas film I snuck off to get my 400 working. Presently it doesn't power on, no led etc.
First check is the psu is dead. But which psu voltage/ ampage/ centre polarity do i need?
Is it 9v centre negative or positive? and how many amps? just going to run a flash cart and a 48k ram board.
TIA! Iain
