Mac monitor help

[47ronin]

Ok this isnt exactly specifically a music question....but I hope someone can help me. I recently bought a blue and white G3 mac off of ebay that i want to use for recording. I need to hook it up to my old powermac display which has the larger 15 pin connector...I need an adapter from this to the smaller 15 mini sub VGA on the G3....my question is does such a thing exist, and if so, where can I get one?

Thanks in advance
