As far as I know there are no **STANDARD** PC text
video modes that give
132 columns.
What was *standard* for the time of these cards? Herc graphics
certainly weren't "standard" when they came out. I've not checked,
but I have a couple of Everex MicroEnhancer EGA boards with a
boatload of additional modes--and one of those might well be a 132-
character one. (If anyone is really curious, I can check).
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...
Ever worked with a Hercules Graphics Plus? It can blink, as well as
support 12-bit character width and software fonts--all in text mode.
There was a also mode setting to use 8-dot wide, rather than 9-dot
wide characters. Double-width was certainly possible in test mode.
Perhaps a scheme to use the extended character set to display 132
characters could be worked out, but I hated the 132 character display
on most terminals, even the 14-inch ones as being too grainy and hard
to read for my weak eyes.
Cheers,

Hi,
80*25 and 40*25.
As far as I
know there are no **STANDARD** PC text video modes
that give 132 columns.
What was *standard* for the time of these cards? ....I have a couple of Everex MicroEnhancer EGA boards
with a
boatload of additional modes....
So what?
The OP needs modes which work on ALL adapters, not non-standard modes which
work on a small number of Mickey Mouse cards which noone uses....

So, there's a lot of cards out there that do 132 column mode. Back when
I actually used text-mode (in Linux), almost every machine I tried with
a PCI VGA card had some 132xblah video modes.
And, the VESA mode number are somewhat standardized. If you can select
a certain mode, you *do* know what resolution it'll give you. That's
the whole point behind the VESA standards.

He does? I'm sure that someone using Dave's VT100 emulator couldn't
decide that because they want 132 column mode, they'll spend some time
to figure out what works with their hardware, and specify it in a
config file somewhere. :(

These cards can't really be considered VGA. They're actually SVGA, and
it's a de-facto standard for SVGA cards to produce the Hercules
resolutions without complaint. A real VGA won't. At least it won't on
any of the first-generation VGA machines I have in the pile.

Um, no. It's the other way around. I think the number of clone VGA
cards I have ever seen that would produce/emulate Hercules 720x348 mode
1. I could count on one hand, and 2. were all manufactured before 1990.
Now, if you had said clone *EGA* card, I would have agreed with you.
Most clone EGA cards accepted a monochrome monitor (pinout was the same)
and would produce either Hercules 720x348 or EGA monochrom 640x350 on
request.

You're saying that your 8800GTS emulates Hercules mode? 720x348
monochrome? Seriously?
If so, how are you testing it? What program are you running and in what
environment?
