Not sure exactly where to post this. I have a Dysan PAT 2+ Perfromance and Alignment tester. Its two modules, one main unit with keypad/display and a second Apple Adpater in an identical shell. The connector together in some way. While I did locate the user manual online it was of little help in determing the power supply needed. Hope someone here has one and can help out with sepcs. I will attach the maual. It is an interesting device which I assumed was only for Apple II 5.25" floppy drives, but the version I have can also do 1.44mb and 720k. It can also do Sony OA-D30,OA-D32V & OA-D32W. But I am not certain if those drives also transpate to Mac Drives, the M0001 used a 34v if I recall (memeory made be shaddy here). But like I said, it has no power supply adapter or even proper ribbon cables to make it all work. And there is very little info found online. Primarily I want to at least test the power before posting for sale since the effort to get the test floppies, cables, etc may be too much of a project for myself to take up.
