Another description mentioning that it isn't standalone:
"#9GX
Number Nine Graphics Xccelerator
16-bit ISA Video Card
PC007200-2
NEVER BEFORE SEEN IN CAPTIVITY
PROBABLY THE RAREST PC VIDEO CARD IN THE WORLD
imagine a 1991 ISA video card with 6MB of RAM!!!
really rare. nobody has pictures,
Wikipedia doesn't accurately describe this card
nobody else has one or describes one
when #9 sent a sample to a magazine for evaluation the drivers didn't work
and the magazine was unable to test it
based on the TI TMS-34010, uses the TIGA Driver
there is this blurb online:
The PC DECwindows Motif supports the ...
Number Nine Computer Corp. #9GX Graphics
Xcellerator card, 16 or 256 color, 640 x 480 or 1024 x
768 or 1280 x 1024 (with a Texas Instruments Graphics
Architecture (TIGA), Version 2.0 driver;
this card looks pretty much like new,
it is in beautiful condition except for a hint of 'greasiness'
around the memory chips that reminds me of leaking capacitors
but these capacitors have not leaked so perhaps somebody
sprayed the sockets with some sort of contact cleaner
This card is not a stand-alone video card
it is an accelerator that only works with the pass-thru feature connector
and a second standard VGA card
although it does mentions an optional VGA Snap-On Module (#9VGA)
so with such a module it could be a stand-alone card
This card is fully populated with 2MB VRAM
(8 soldered KM424C256Z-10 and 8 socketed D42274V-10)
and 4MB DRAM
(8 socketed HM514400ZP10 1meg x 4bit)"
