By trade I work in IT, and I dabble in mechanics as a hobby.  By chance the two crossed when I was called out to look at a computer built into an automotive diagnostics machine.  I fired it up and other than a noisy fan it appears to be working, I was able to guess my way through checking the timing on a car.  The man who owns it knows very little about mechanics and is looking to get rid of it, does anyone here have experience with one of these?
