I have the following one and It has worked flawlessly I use it on a 1200 2000 and 500 without any problems The MV1200 is an external scandoubler for all Amigas which takes the standard Amiga PALor NTSC output and scandoubles it for use on a PC type VGA/SVGA monitor. It supports full 24bit colour in all non 15Khz modes. High precision TTL circuit used for pixel clock generation. The MV1200 also has an optional FlickerFixer module to promote interlaced screens to non-flickering displays
