The Powerbook Screen Tester program for the 170 and 180 was already written, but I wanted to have the flexibility to check each element ( red, green, blue ) for my new 180c. So I wrote this screen tester program which cycles between black-white-red-green-blue to test the active matrix screen. You can also just flip between black and white using the appropriate keys if you have a 170 or a 180.
Why test the screen? Well, there is nothing more frustrating than dishing out thousands of dollars, only to find out that there is a burnt out pixel in the just the right place to really annoy you. Before you go and buy a powerbook with an active matrix screen, take this program along with you to make sure the machine you buy has the best screen possible.
This program is freeware, but if you really have a need to express your gratitude, you can email me at:

p.s. if you happen to be in the Boston area, I always enjoy a few good dark beers!
