Ok how do you tell the version of Apple Scsi. I suspect I have a revision c, but after looking at the modification faq I'm not to sure. the mod diagram shows pin 24 an c16 close to each other, but on the card I have they are on opposite ends. The model no. is 607-0291-c which is why I figured its a rev c. The only other apple no I find on it is 341-0437-a Sheane
