The Toastscans work very well with the Video Toaster when using an Amiga 4000 as the A4000 only came with a 23 pin video out requiring you to use the 23pin to VGA/SVGA adapter. This unfortunantly did not alow usesrs with the Toaster 4000 to use any of the non genlockable video modes. The Toastscan not only alows a person to use the Toaster on any Standard PC monitor so you dont need to us the 1084 or the 1960 Amiga monitors that have lousy image quality but also use most of the video modes available.
