What video modes are available on the LCD display of the Zenith
TurboSport 386?  The Zenith documentation is astoundingly
uninformative.  As far as I can tell, it only seems to be able to do
CGA emulation.

What about monitors plugged into the video port on the back?  We've
tried a Zenith ZCM-1492 VGA-capable monitor with no success (obviously
gross mismapping of characters on the screen).

Any info would be most appreciated.  Thanks.

The TurbosPort 386, not the "386/e", only handles double scanned CGA (640x400)
The 386/e has a VGA video card.

The fact that the FTM Z-1492 is a VGA monitor has very little to do with the
quality of its output.  This depends on the video card.  Thus, should the FTM
pins fit your CGA adapter, you should get CGA output.  For some reason, I
think you should have trouble connecting the two given that the FTM expects an
analog output.  But I may be wrong...

I hope this helps

on mine, onboard display does some sort of kludge CGA, with 400 lines
vertical, while the optional expansion box can take an EGA card with
appropriate ROM-based video mode setting....
