Does anyone know of any telecommunications software that supports 132 columns *on screen* (as opposed to 80 columns on screen with the other 52 columns scrolled off to the right) for a Zenith Z-248? The Z-248 in question has just the standard CGA adapter and amber monitor - not EGA. Ideally, no additional hardware would be necessary. The quality of the 132 col display doesn't have to be wonderful, just readable for infrequent but specialized applications. Thanks! Keith <kdale@bbncc-eur.arpa>

Have you figured out how many pixels you'll have per character on
a 132 column display? With a standard CGA, assuming you leave
one pixel between characters, you'll have 3 pixel wide characters.
It's hard to see how anybody would ever call that readable.

Several years ago, I developed a 3 pixel wide font that, all things considered, is much more readable than I ever thought it would be. If anyone is interested, I can mail it. Moral: If it seems impossible, it's worth a try. Challenge: a 2 pixel wide font! Frank Prindle Prindle@NADC.arpa

Allow one row of pixels per line to separate rows of characters; this turns out to be "free". Result: a 640x400 display window will only accept 16 rows of characters. Of course, with one pixel of horizontal separation, you can still get 213 characters per row. Somehow, I don't think this is the real frontier of display technology...

In fact I'll bet I can get 128 distinct patterns in a 1 by 7 matrix.

Well, I know how I came up with that, but I'm not ABOUT to admit it now! It
was past my bedtime when I scribbled this, and my brain had already retired.
Thanks for a little rationality, David. However, this doesn't mean I want to
read a 1 by 7 font, or even 2 by 24...
