Re: Commodore 65 and DIN8 cable

Furthermore, although PS/2 keyboards and mice use a 6-pin mini-DIN, only 
four pins are used and just about every cable you will find only has 
those four pins connected.

For what it matters, some video games like the Turbo-Grafx 16 tend to 
get modded with 8-pin mini-DIN for RGB output, and it is some kind of 
"standard" when it comes to RGB cables on various systems.

Sun SPARC workstations use 9-pin mini-DIN, if I recall correctly, or 
were those 8-pin just like the SGI's you refer to?

Best regards
