There is no way to have NTSC-out on a Macintosh LC if an Apple IIe Card is
installed. RasterOps, Truevision, or the Computer Video RGB-to-NTSC converters
won't work because they require an RGB signal with NTSC timing. The Macintosh
LC doesn't have this kind of video port (that is, it doesn't have NTSC sync
timing rate built into the board).
Here are two workarounds:
* Use an Apple IIe or Apple IIGS as your NTSC projection system.
* Use an LCD overhead projection panel compatible with the Macintosh LC.
Any panel compatible with the 12-inch monochrome or 13-inch RGB monitor
will work with the Macintosh LC video port. This solution has the
advantage of being a Macintosh environment projection device. We are
unaware of any LCD projection panels compatible with the 12-inch RGB
monitor.
Another option is using a video card such as the Spectrum/8 LC Card. You have
used the slot, but now have a video board that supports not only large screen
monitors, but also supports video-out with the addition of the RasterOps video
expander or the Computer Video NTSC encoder. It gives you 256-color graphics
for the Macintosh LC. This still doesn't allow for both the Apple IIe card and
NTSC video-out.
The Spectrum/8 LC Card supports the following displays:
- SuperMac 19-inch Platinum Display
- 21-inch Platinum Two Page Display
- 16-inch Trinitron Display
- 19-inch Dual-Mode Trinitron Display
- 19-inch SuperMatch Color Display
- 21-inch SuperMatch Two Page Color Display
- Apple 12-inch RGB
- Apple Color 13-inch
- Apple Macintosh Portrait Display
- Apple 21-inch Monochrome
- RasterOps 19-inch
- Radius 19-inch (1152 x 882)
