No cheering from the audience. After checking with friends locally and in CA I offer my apoligies. Not being heavy into EE I made a mistake. The limit on the power supplies is not in the wattage they pass through to the monitor, but to the amperage. The cx and ci power supplies are capable of 3amps out to the monitor. The 13" monitor has a nominal power usage of 90 watts. The power supply apparently does act as a pass through but has a limit of the amperage that it can pass through - 3amps @ 120volts. It is this figure that monitors that connect to the power out must hold to. I am not sure of the amperage on the 13" color monitor, but from the problems that I have seen with it and the power supplies on the cx and ci it must be damn near 3amps. The power supply has a beefier rating and can easily handle more that 3amps. According to friends at Apple, if you could produce a two page color monitor that needed less than 3amps of pressure (?), then you could concivebly connect it to the power supply on the cx and ci. My apoligies to those I have verbally flamed for this, I hope that this clears up this discussion. My thanks to my friends still at Apple who straigtened me out on this. BTW - Did the guy ever figure out what was wrong with his cx? Blacksheep Senior Systems Engineer -- Darrin R. Woods woods@convex.com This is a guest account.
