Does a video card exist for the Apple ][+ that can display 132-column text?
If so, what brand/model?
I know this isn't exactly what you are asking about, but here is a cheat...
Apple ][+ >> Apple Serial interface card >> Keyspan Serial to USB >> iBook USB >> Terminal application with a window sized to 132-column width
Videx Ultra Term would. Actually a 160 column text. But you might have to adjust the mono color monitor to get them all on the screen. When I had one I had to adjust the screen to get them all on there.
160? Wowzers! :o
A 160 would be a nice round doubling of an 80 column. It'd be interesting to know if it was a simple narrowing of the font or running a higher frequency.
