The Framegrabber 256 is an external digitizer which is available in both NTSC and PAL versions. It connects to both the parallel and the Amigas monitor port. The monitor in turn connects to the digitizing unit. This allowed the digitizer to be operated using one monitor to switch between the video source and the Amigas video by means of a switch on the front. It can digitize in both 256 greyscales or 24-bit colour. In order to digitize in colour, an RGB video source is required which was rare on household equipment. There is also a similar model called the Framgrabber PAL (there may also be a North American version called the Framegrabber NTSC) which features a built-in RGB splitter for domestic purposes.
