Ignoring for the fact any design details, let me explain that I am
one of approximately 3% of the population who can see the flicker on a normal
display. This is not a big deal with white lettering on a black background
(or any color lettering on a black background), but it is mind-bogglingly
annoying whenever the background is light.
Does anyone know of anyway to adjust the Mac to get white letters on
a black background (I can get the black desktop, but you can't do much with
black letters on a black desktop) Otherwise, working on the Mac, which
has to be done, is plainly speaking, and for no other reason, sheer hell.

There is an applicationg called "Reverse Screen" that, when run, reverses the screen. It is very small, and free (if I remember correctly). Since I am in the lucky 5-10% who can see screen flicker, but ignore it <purely imaginary statistic>, I deleted it long ago. It could probably be found in SUMEX... If you can't find it anywhere, I could dig it out of a pile of software at the user group at home, but that might take a while... I won't have access until January. b.bum wb1j+@andrew.cmu.edu

The only disadvantage to this is that the cdev puts up a rectangle on the screen until you turn it off (each boot). Quite a disadvantage, I think. (I also think that Reverse Screen dies on a II, but that could be fantasy). Bob Hablutzel BOB@NUACC.ACNS.NWU.EDU

I seem to remember that CloseView (bundled in System 6.0 and later) not only allows you to magnify the screen, but also switch to white on black. Anyone else know if this is correct? (My manual is at home). Wayne Folta (folta@tove.umd.edu 128.8.128.42)

[asked what to do about MacIntosh] Well, at the risk of looking foolish asking how you tested this: did you try using the Mac without any 60Hz light sources nearby? Occasionally, the combination of intensity flicker from lights (reflected off Mac) and the internal raster aggravates the situation. Also, you might try working with the screen quite dim, so the contrast isn't so high, which means the smaller contrast caused by raster is less noticeable. Good luck. If anyone out there writes a patch to System6.0* for Macs which inverts the application screens, I'd be interested for curiosity's sake. -- Alix' Dad ( Carl Witthoft @ Adaptive Optics Associates) " Axis-navigo, ergo sum." {harvard,ima}!bbn!aoa!carl 54 CambridgePark Drive, Cambridge,MA 02140 617-864-0201 "disclaimer?

My system software disks for either 6.0 or 6.0.2 came with an INIT/cdev
called "Close View," primarily designed as an aid for the vision-impaired.
It automatically expands the screen image to a desired magnification resolution
(ugh--like Fatbits, or the Apple II's lo-res) and can also invert the
entire screen display (white text on black backdrops--great for reducing
my daily dose of radiation...).
This should be available from an Apple dealer (free) if you don't already
have it.
HIH, Nick.
