Anyone still have a working machine with an IBM VGA Card?
Would really like a dump of the bios so i can try it out a bit with a
little project of mine.

If you don't know how to dump it, please contact me so i can give you
a tool that will do it for you.

Was there ever an off-board IBM VGA ... only VGA ... I can't remember ....?
But we've got plenty of working machines with onboard IBM VGAs.

You will find dumps of the two known variants of the IBM SVGA/A
Cirrus-based microchannel SVGA card here:

Indeed there was. It was an 8-bit ISA card for XT/AT upgrading. I've tried them in combo with MDA, CGA and EGA for dual displays
and they worked fine. In concert with CGA, the VGA, does mono modes, in concert with MDA it handles color modes. Depending on how
the EGA is switched, it can go either way.

Being 8-bit only, its not the fastest VGA around, but they work.

There was an early IBM VGA ISA-bus adapter, IIRC. For "upgrading" all those
"obsolete" CGA/EGA XTs and ATs. There's probably an ISA-bus XGA/XGA-2
somewhere. Whether the BIOS is quite the same (XGA uses specific areas of
the BIOS Extended Data Area) I dunno, since I'm not into ISA-bus systems.
Who has a Model 35 or 40?

Speaking of which, I'm looking for an IBM 8-bit VGA card for an XT.

Anyone got one they want to sell or trade?

Hi,

I think he meant the original VGA offered by IBM for the ISA bus - the
full-length, 'half height' card with the metal-canned VGA chip. I have
already contacted this guy since I have such a card hanging here on the
wall as decoration - next to the genuie IBM EGA with the RAM
daughterboard.

Best regards

Alfred

Yes was looking for the bios of one of those, thanks very much for
sending, now let's hope it somewhat works :)

Doesn't really matter i think, both would use the same bios i think.
But i recall having seen a actual isa vga card sometime in the past.

I've stripped a few 486 era clones down that had 8-bit VGA's with an Orchid chipset. Those card's form factor is smaller than the
IBM one by quite a bit. They're about the size of a clone dual comm card, whereas the IBM one is full length. Might make a
difference if you're tight on full length slots and want to slip something in one of those half length one behind the bays.

Yep, he probably did, but I thought this one might be of interest too.

Hi Tony,

I've already got a couple of 8-bit VGA cards, including a very nice Video-7
card. However, I'm looking for a genuine IBM 8-bit VGA card to go in an
all-IBM XT.

Did IBM also make a 16-bit ISA VGA card? If so, I'd like one of those for
my XT-286.

Carroll

I have never seen one if it does exist.
