Check out this vintage Sun Analyzer I just found..

I hooked up the hemi to the sun machine and most of the machine actually works. Big information overload when you seing all those guages and lights flashing!

The timing light has seen better days. I think it is the inductive pickup since the magnet seems to be broken inside the pickup and the light does flash once in a while.

I can't get the cylinder cancelling function to shut down individual cylinders for comparson but maybe that is a function of the broken pickup.
