Sun Diagnostic Computer help needed

I was thinking the same thing and havent had a chance to hook up a car yet. There is one more disc that I didnt pull from the computer. It does the 80-86 GM's. So my plan is to hook the 80 Trans am up and see what all it allows me to look at. The one thing I noticed so far is the screen is not very bright. Maybe that will change once you go into the programs. This week I didnt run into one shop that ever used one. With me being a rep for tires I go into 10 -15 shops a day. Its just hard for me to believe no one used these things. That means that the old guys that did are gone and since the equipment is obsolete no one kept them. Damn, that makes me old because I used the old analog one that we had in the late 70's.
