What is Apple Macintosh II Video Card utility?

This unsupported utility is a "Monitors CDEV Extension" which may be of assistance in obtaining interlaced, RS170-compatible video output signals from a Macintosh II-class machine equipped with the Macintosh II Video Card.  It may support 1,2,4, and 8 bits-per-pixel interlaced video.  In also may provide an optional "no flicker mode" for the 1 bit-per-pixel mode.  This mode eliminates the flickering caused by thin horizontal lines (like the racing stripes at the tops of windows) that occurs when Macintosh video is transferred to video tape.

Audience:

This video utility allows developers and video-knowledgeable  users to obtain medium quality video output at extremely low cost.  This is not intended for the unsophisticated user.  If you don't know how to make a video cable, this software is not for you!  
 
Pluses:

+ Supports 1 to 8 bits per pixel RS170 video output
+ This type of video can be video-taped
+ Flicker filter improves image quality in 1 bit per pixel mode.
    
Minuses:

- Requires a special cable.
- Flicker filter slows the computer down 20% to 40%.
- Flicker filter uses about 48K of RAM
- Not 100% broadcast-quality RS170 signal.
