I acquired two interesting Apple II Rev 3 motherboards. One is a board that was thought to be a clone but I wanted to explore if it was actually a prototype. As with the Apple II Rev 0 prototype, one of the Rev 3 motherboards has no solder mask or graphics.
I've gone through it with a fine toothed comb and I cannot find any difference from a normal Rev 3 motherboard. What I don't know is if there was a clone that was that exact at the time. Does anyone happen to know?
I am attaching some images for review.
For your Question, I don't know...
I have a Rev-03 Apple ][, and an Apple ][+ with a Rev-01 Board.
Those are really nice Photos..... Thanks for Sharing...

Probably a clone, but you never know 100%. Strange that it has different colored slots.
I would be surprised if Apple ever ever made a board without their copyrights on them...
Slots 6 and 7 have been previously replaced. You can see the solder flux on the bottom side. Thanks to Corey986, it has been determined that there were, in fact, prototype boards that did not have solder masks or graphics internally at Apple.
