Just got my old Amigas 500 working including its hard disk. Amazing really as it's not been powered on for 25 years. Feeling a little emotional TBH.
@mcscx Will do. I tested the power supply, checked its caps, it was fine. The battery in the A501 had leaked so I removed it and cleaned up the board and the memory on it was okay thankfully. I think I can repair the clock and solder in a new coin battery. In other news, my A3000 motherboard was more badly damaged by battery leakage, but might be fixable.
