Here is a description of the monitor, from this website: http://www.sourcesecurity.com/docs/fullspec/AMC21.pdf
ADEMCO Video’s AMC21 is a deluxe 21-inch color monitor that provides crisp, detailed images. Its large viewing area and high resolution is advantageous for applications requiring detailed picture-in-picture or multi-screen formats typically associated with quads or multiplexers. The AMC21 features easy to use on-screen display (OSD) menus and convenient front-panel push-button controls that make setup quick and easy.
The AMC21 is ideal for worldwide applications. Installers can choose setup menus in English, French, Italian, German and Spanish. The monitor also features an auto-sensing feature that automatically detects whether a PAL or NTSC video source is connected, and a universal power supply, allowing it to be powered by sources ranging from 90 to 245 VAC and 50Hz or 60Hz. An illuminated green LED beside the power button confirms that power is being supplied to the monitor.
The AMC21 also features a latching power switch which remains in its set position–either on or off–regardless of incoming power status.
The monitor has S-VHS capabilities for the highest quality video when connected to a compatible VCR, such as ADEMCO Video’s AVR960SV, and an audio input and output that allows operators to listen-in as well as view the monitored area. This is especially convenient for secured entry areas.

A quick Google search shows this monitor currently selling new for $470 and up. The only thing that's missing is the power cord, but it takes a standard computer power cord, like pictured below, which can probably be purchased for $10 or so.

I have this riding in the trunk of my car, and will hang on to it until Monday. If nobody indicates that they want it by then, I am dropping it off at Best Buy to be recycled. I can meet most places near downtown, or the north metro, but I am not inclined to drive all over town, since it's free.
Send me a PM with any interest, or questions. Thanks!
