There is a small monitor problem on every Next display I've ever seen: the upper left edge (about 1/4 inch) is slightly bent. Is this the problem you're referring to? Does anyone not have this? One of my colleages (sp? where's webster when I need it!) suggested it was probably due to a video retrace problem where the beam hasn't had enough time to settle down after returning from the bottom of the screen. This actually makes quite a bit of sense given the size of the screen and the fact that the glitch only occurs on the upper left part. Any other speculations? A small bit of trivia for you: did you realize that there are 2 small surface mount LED's on the slab motherboard? One (almost hidden by the hard disk) appears to blink regularly. The other (in the front left-hand corner) blinks irregularly. It seems to be tied to keyboard input or possibly screen drawing (it shines steadily when you type return in a shell window). Maybe it simply denotes bus traffic? Cheers, --mike Mike Carlton carlton@cs.berkeley.edu
