Guess I ought to hang a scope on one of my Apples to see how it compares to your IIc. Filtering out color burst isn't going to do anything to boost the bandwidth of your TV set. A color TV displaying a B&W signal has no better response than it does in color, except that the text isn't tinted with false colors. I hacked into one of my color monitors to remove the 3.58 MHz trap and delay line in the luminance circuit, which did improve sharpness at the expense of some color crawl and fringing, but 80 columns is still pretty hard to read. If you have a II or II+, it's fairly easy to activate the color killer circuit permanently. I thought the IIc had a color killer like the other Apple IIs, in which case it doesn't put out color burst in text mode, only in graphics. The first 100 or so Apple IIs lacked the color killer circuit, and it was a common user hack to add it, or Apple would exchange motherboards.

Other experiments I intend to try when I have some tuits:

Will your LCD TV or monitor display Apple II text? Graphics? What brand & model is it?

Will your DV camera accept a video feed?

Can you video tape off your monitor screen? Is it best to use a solid state camera or one with a pickup tube? Will solid state pickups show bars rolling thru the screen? There are some demos I'd like to post on the web, but since they require peripheral cards, they can't be emulated. I'll need to shoot the screen.

My to-do list is pretty long at the moment, and these are low priority.
