Hi folks, A colleague at work has lent me his A2000, so that I can get it working again. The original problem was that the PSU had died, but during my investigation the wires to his ROM switch fell off :>( What I have is this; A rev 6 motherboard, with two ROM chips piggy-backed together at the appropriate location. From there go four wires. Two are joined together at pin 10, one is linked to pin 21, the last to pin 30. All four were then linked to a DPDT switch, which itself has opposite terminals of the two poles cross-linked together. What wires should I solder to which pins of the switch to get it working again? All advise gratefully received! Regards, Ian -- Ian Deaville - ian@deaville.demon.co.uk Connecting via Demon Internet Ltd
