None of amiga hardware sites has any pictures or infos about rev 7 mobo. Some doesn't seems to know that it exist.
Is it rare? Does anyone know how it differs from rev 6 mobo?
It's a mystery, here are my theories in order of likelihood.
There may have been a revision 7 designed, but it might not have made it to production before revision 8 was done. The Amiga 2000 revision 5 suffered a similar fate.
Or it was designed around the a3000 agnus (8372ab) and they had problems with it (

Or it might have suffered some other mystery problems.
Or they may just have skipped a revision, in case they pushed back the a500+ launch but wanted a blank space.
Or they wanted to create a conspiracy.
