  Not quite true.  The output of the original TurboSport is plain vanilla
CGA.  The 15.75 kHz variety.  The FTM will only take the 31.5 kHz of a 
tru VGA card.  The VGA system (card/monitor combo) achieves CGA emulation
by double scanning the CGA and sending it at 31.5 kHz.  The monitor senses
this and "stretches" the display slightly so that the resultant picture
fills the whole screen.

  So, even though your TS 386 has a 15 pin D connector (ala VGA) it only
sends out CGA signals.  A small adapter cable is supplied with every
unit to convert back to a 9 pin D connector for connection to a CGA
monitor.  The next version, TS 386/e, put that 15 pin connector to good
use.  It has true VGA output.

  Hope this helps even more. ;^)
