Not likely - as
far as I know there are no standard PC text
video modes that give 132 columns.
Long ago I had a 132char driver for the Hercules/TTL mono video card.
I was based on the 720x348 mono graphics mode.
I also remember the several of the SuperEGA bios that supported the
extended MDA modes:
46h Text 132x25 (8/9x14)
47h Text 132x29 (8/9x12)
48h Text 132x32 (8/9x11)
49h Text 132x44 (8/9x8)
As far as I know there are no **STANDARD** PC text video modes that give
132 columns.
Yes, at 720 dots, you can do a 5 point wide font for 132 columns on a Herc.,
but I don't have Hercules (or any MDA) cards in any of the system that I
actually use on a regular basis (POLL: How many here are using Herc cards
in systems they would want to use as a VT100) - I'm also not sure I could
achieve all of the attributes (Can you blink graphics on a Herc? - I suppose
you could do it in software, but the only MDA machines I have here are XT
class which would make for "interesting effects" :-)
I think I also mentioned that I wasn't quite ready to do a bitmapped version
of the terminal yet. I agree that it would be nice to do eventually, as I
could support double-width/height characters as well...
Does anyone know if any of the more modern (ie: VGA) cards support enhanced
132 column text modes? - And is the video addressing basically the same
except for 132 words of memory per line instead of 80? And where to find
more information? If it could be reliably determined that support was
there, and it is compatible with my text windowing code, it would not be
difficult to add support for it.
