Sigma RealMagic DVD Decoder (added to my collection in 1998 or 99)

• Hardware DVD MPEG decoding
• VGA pass through overlay

This was used to playback DVD video on my old IDT WinChip 200mhz PC (which was soon upgraded to an AMD K6-2-400mhz), it allowed for either windowed, or full screen perfectly smooth playback of MPEG DVD video, with near zero CPU utilization, which meant I could work on other things while watching movies with no slowdowns.  The PC is long gone, but I have kept this card all these years.
