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. -Dean (dean@u.washington.edu)

The Zenith documentation is astoundingly The TurbosPort 386, not the "386/e", only handles double scanned CGA (640x400) The 386/e has a VGA video card. > What about monitors plugged into the video port on the back?

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 Michel Biedermann michelbi@oregon.uoregon.edu U. of Oregon ZENITH Student Rep.

We've 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.... russ -- Russell Shackelford School of Information and Computer Science Georgia Institute of Technology, Atlanta, GA, 30332 russ@prism.gatech.edu (404) 834-4759

For some reason, I > analog output. But I may be wrong... 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. ;^) > Michel Biedermann michelbi@oregon.uoregon.edu > U. of Oregon Jeff Easton Zenith Data Systems Systems Engineer OEM Engineering easton@andrews.edu -- or -- ..uunet!zds-asg!zds-oem!easton Save the Otters!

does anybody know if there is an upgrade option to make an original Turbosport 386 into a VGA machine???? thanks, russ -- Russell Shackelford School of Information and Computer Science Georgia Institute of Technology, Atlanta, GA, 30332 russ@prism.gatech.edu (404) 834-4759
