The earliest VGA cards tended to be 8bit, or 8/16bit
autosensing. Paradise was the main supplier, though Oak and Tseng
Labs produced some as well. They generally had only 256k of RAM
onboard and would do 16colors at 640 x 480. No acceleration either,
as it was before Cirrus and the others started trying to speed up
Windows screen draws using the graphics chipset. VGA actually had
it's beginnings on the MCA bus with the PS/2 but was then adapted for
the ISA bus by the 3rd party vendors.
