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 (https://groups.google.com/forum/?hl=...w/RLDTexh-nSUJ).

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.

It's very similar to a Rev6.

Not my machine and these are the only pics I have.

Nevertheless, not very exciting.. Just a minor revision that didn't live on for very long.

The rev4 has also been spotted in the wild, it was also apparently very short lived. Didn't get good pictures of it from the owner so the evidence isn't archived. As far as I remember, it was closer to rev3 than rev5.

I've only ever held these revs in my greasy hands: 3, 5a, 6, and 8.

(EDiT: That might be Rev 5 and 6a... memory is a little weak on this one...)

I suppose that 1mb chip hack is easy as rev6 mobo to do? I've one, just changed 1mb agnus 8372a and 2,05 roms to it
