ISO: Sun 386i color video/keyboard/mouse cable

[Josh Dersch]

Subject line says it all...  From my research this is an oddball cable 
with a  "DB21W4" connector on one end that breaks out into 4 BNC plus a 
keyboard / mouse connector for the lamentable Sun 386i series (with 
color video).  (Part number 530-1366.)  I have acquired one of these 
machines and have an odd inclination to make it do something... anyone 
have one going spare?

Thanks,
Josh
