Anybody know of readily available data for, say, 7x9 dot-matrix characters?
I'm looking for a downloadable rom image for something like in old video
cards to
paint ascii characters on a display.
For example, my Polymorphic Systems Video Terminal Interface (VTI) card uses
an MCM6571A (or it could use a 6574) -BUT- I do not need exactly that
font - any 7x9 data will work. Spent the past hour trying terms in
google w/o
anything usable turning up.

Does it need to be *specifically* 7x9? There are various bitmapped fonts
floating around.

Drat I just threw out that data. Well not the ROM data but the manual
for a video display
that had the character set. Remember the roms used desenders so it was
more like 8x12?.

I have (but not accessible today) the IBM 5150 CGA and MDA character sets
as course dot-matrix HP PCL , and as Corona Data (Cordata) fonts

Sometimes it's funny what you have hanging around. I discovered that I
still had the font diskette for a Hercules Graphics Card Plus monochrome
adapter (the card itself is installed somehere around here). For those
unfamiliar with this beast, it was basically a Hercules monochrome card
with a RAM in addition to a ROM for font generation.
Anyway, I zipped the fonts up and sent them on to Mr. Swiger.
I also discovered that I have a set of 3 ROMs from a Fujitsu monochrome
terminal with an EBCDIC character set. Don't know what those are good
for.
Cheers,
Chuck

Not directly applicaable, but it may be worth rememebring that there's an
8*8 font in the IBM PC (etc) BIOS ROM to be used for displaying
characters in the CGA graohics modes. I assume it's in all clone BIOSes
as well, at least all old ones.
I think there's a software interrupt vector that points to it on a
running PC, so it should be easy to find.
Come to think of it, aren't there similar character fonts in most linux
(and *bsd) distributions to be used for the same purpose. On my old
debian machine, they seem to be in /usr/lib/kbd/consolefonts
