Mimi Dvi Out


hello I have an older model imac, 15 in.lcd display, 3 years old, 700ghz processor, 256ram .My problem is it has a mini dvi video out port I would like to get working but the new hardware does not support my computer I was wondering if you could refer me ,to perhaps a place online I could find an older adapter , a used mac equipment website , any suggestions are appreciated , I seem to have exhausted most of my options. thanks .
I think this is the correct part number: M8639G/A

Doing a search for that on the Apple Store site will help. I don't think we can link directly to it as the sessions time out after a few hours, like DeltaMac's.
thanks much for your help seems to be mini vga as expressed by deltamac,stay safe ElDiabloConCaca .druid.
