A possible hardware fix would be a duct tape job on the TOD Enable switch -- or maybe the CE could by-pass the switch. I doubt there's much, if any, current draw when the switch is closed.
Any IBM hardware folks care to commment? George Haeh 416-465-2292 [EMAIL PROTECTED] ----- Original Message ----- From: "Dennis G.
