Svideo is mini din 4, as are the adb cables used in most mac 68k and early powerpc systems. PS/2 is mini din 6, rather than 8. Mac and end-user SGI systems tended to use mini din 8's for their serial ports, with similar pinouts- similar enough that a person could use most mac serial cables on SGI systems equipped with the din8. In fact, I use an old Mac laplink cable for my origin 2000's console. -David On Wed, Feb 10, 2016 at 4:28 PM, William Levak <wlevak@sdf.org> wrote: > > S-video is mini DIN 8.
