Thanks and I will start a new post shortly. Thanks for your advice.
Yes, from what I've read/heard, this was the first personal computer with a fan. To make sure the computer was getting adequately cooled, they would filter smoke though the computer to see how it moved through the machine. So yes, its sort of both testing the cooling. The machine was sold to me buy a friend who worked on the original project. I have all the manuals, the carry case, working correct 20MB HD, 8mhz board, etc. I even have the ethernet card but don't have it hooked up right now. The guy had some really cool stories about the machine and seeing how I know there cannot be more than 3 in the real world it has to be one of the rarest/most iconic Mac ever produced.
