Someone I work with just got a Mac II (1 Mbyte ram, 40 Meg HD) with a Sigma Laserview 19" display and video board. The system has been crashing almost consistently since he got the system (about a week ago). So far it's bombed in Quark, MS Word, and even the Mac II tutorial disk, sometimes at varying places, others at the exact same place (tutorial). Sigma provided a little Cdev program to control resolution, font size, and screen blanking, which is accessed through the Control Panel. You can select it fine, but after that, once you move the mouse, you get a bomb and a low ID error (1-3, I believe). I should mention that the system was originally shipped with System/Finder 6.0/6.1. I heard that Sys 6.0 had some problems, so I upgraded to 6.0.2. Some things worked a little better, but not much. I also tried S/F 4.2/6.0, with no better luck. The Laserview cdev (v. 1.21) was also pulled out of the System Folder, and again not much change (still crashed occasionally). I haven't had the chance to verify his tutorial disk on a regualr Mac II with an Apple video board, but my first feeling is that there is definitely something about the board that the system doesn't like. Sigma provides a diagnostic disk, and all tests passed. I didn't recommend the monitor/card, but I will probably be the person more or less responsible for getting the system working. I'm going to try to call Sigma, but I'm not positive that they will be able to provide much help, so any help that you could provide would be appreciated.

We have a number of LaserView monitors on macIIs. Many of them have had this problem. After much hassling w/Sigma, they admitted to know problems with the video boards. Press them, and you should be able to get a replacement. John E Milburn (JEMilburn@lbl.gov) Advanced Light Source Lawrence Berkeley Laboratory
