Has anyone tried disconnecting the monitor from a 3b1 box in order to use it on a monitor pedestal? (or for any other reason, actually.) How'd it work? Ken --- staffan@serum.kodak.com

I haven't actually tried it, but if you do, and are considering placing it at more than the existing cable's length away from the left side of the computer (where the cable plugs in), there are two consideratins to keep in mind. 1) The cable should be shielded, and the shield should be connected to the chassis of the 3b1, and to the shield of the existing cable. 2) You should consider using a fairly heavy gage wire, probably from a mimimum of 22ga for short extensions, to perhaps 16ga for in excess of three feet. The power for the monitor comes through the cable, at a relatively low voltage (12V). Longer runs would result in the monitor attempting to operate from lower voltage, resulting in distorted screen images, and possible damage to the circuitry. (Also, longer cables would increase capacative loading, which would lower bandwidth, smearing the nice, crisp video. You could avoid the problems of the power drop in the cable by placing the monitor on a base which includes a 12V power supply, whose input ac is switched by a solid-state relay controlled by the 12V from the computer (so that the monitor is switched off when the computer is, avoiding possible damage to the phosphor. Let us know how things turn out.
