Title: Anyone know which A2000 Zorro II pin is #1 and which is #50?
Post by: orb85750 on January 02, 2009, 01:52:42 AM

I have no diagram.  Under all 4 possibilities, my voltages are wrong, but I'd like to hammer down exactly which voltages are wrong on which pins, and by how much.  I don't have an A2000 manual and cannot seem to find such a diagram on the internet.  Thanks, -Dave

Hi Orb85750; Unless you have a really old MB the Zorro II slots have pin 1 marked on the MB. Located in the far back left. I can never remember if the pin numbers run down the left side first and then up to the back right or flow from the back to the front in odd||even combinations.  Use the pinout list here;Zorro II (http://pinouts.ru/Slots/ZorroII_pinout.shtml) to identify the 5v and 12v pins. And that should set you straight.
(Make sure you dont short the 12v pin when measuring)
Good Luck.

Thank you.  Yes, in addition to needing a new Amiga 2000, I apparently need to buy eyeglasses.  -Dave
