 I have a little info about the card that started this thread. The information
is two data sheets obtained from Diamond Computer Systems, Inc. I got them
by calling (408) 730-5750. All info below is directly from this source,
however it's not a complete copy just random phrases that I thought were 
important.

Data about SpeedSTAR 24 from it's data sheet.

 "The SpeedSTAR 24 comes with 24 bit, true color capability, full super VGA 
  compatability, and includes a studio quality multimedia option. All this at
  a super VGA price"

 "The SpeedSTAR 24 uses Diamond's proprietary technology to provide 24 bit
  - true color - in Windows 3.x or other programs which display 24 bit color."

 "The multimedia option attaches easily to the SpeedSTAR 24 and delivers
  professional level NTSC and PAL video signals with a flicker filter for a
  rock solid, studio quality signal. The Multimedia Option even provides
  simultaneous output of video and VGA signals. This lets you view the NTSC
  in flicker free, non-interlaced mode while recording or editing."

 "The SpeedSTAR 24 comes with drivers to optimize Windows 3.x abd AutoCAD 
  performance, along with a complete line of drivers for other popular
  application programs."

From the spec section:

 "Bus 8/16 bit slot, 16 MHz bus speed"

Note it also says in other section:
 "Standard PC bus compatible: YES"
