   Not true, there are several, and all better cards autosense when in a
8 bit slot and `disable' the 16 bit extension.

   Most all Super VGA cards have enough memory onboard. Being in a XT only
slows it down by about 1/2 due to a 8 bit slot.  The big factor is clock 
rate of the system, and more importantly, the speed of the bios.  If the
XT system were using a inboard 386 pc, the video would be quite fast.
