Has anyone else noticed small horizontal bars about 2-3 pixels from the
top of the screen when using the 256 color mode on Apple's Mac II video
card? I thought this was something specific to my system (blown memory
on the video card or something), but now I've seen it on three other
Mac II displays.
I didn't notice it until I upgraded the Mac II to 5 Mb of memory. After
that, if I used *any* video mode with more than 2 colors, I get an
interesting video artifact...
A CLOCK!! If I use the 4 color mode, I can see a tiny clock with full
hour:minute:second format. As you progress to 16 and 256 colors, the display
simply looks 'gliched'. I tried removing "Menu Clock" from the system folder,
thinking it was a bug from that program but that wasn't it.
What is it?! Has anyone else seen this phenomenon?
