Feature list:
- 8 different raster images
- 3 resolutions available for each image combination: 640x480x60Hz, 800x600x60Hz, 1024x768x60Hz
- Small size (almost credit card size)
- Portable: battery powered operation (regular 9V-6F22 type)
- DC power adapter operation: 7.5V..12V
- “Designed to box”: fits perfectly into a low cost plastic box
