Does this actually work?  Do you get NTSC video output which includes the
EGA graphics in full resolution? (or as close as NTSC can get, anyhow?)
Seems fairly unlikely to me, especially for only $400 - remember, EGA
graphics are produced at entirely different horizontal and vertical 
rates than NTSC, and conversion between the two is NOT trivial.  What
does this card actually do?
