Hello!
Have you ever heard something about the A3400 project??
Some years ago a friend of mine has gifted to me his A2000. It had a nice configuration but a particular label on the bezel catched my eyes. It reports "Commodore A3400" with the same style of C= A1200 labels.
Unfortunately he didn't remember how he found that label.
Here is a scan:

Looking into the amiga-hardware archive, I've discovered that
the A3400 should have been an early project name for what eventually became the A4000.
My label looks exactly like the one in this
picture.
Do you know how many and if these babies are around?
It is an interesting story. I've never heard anything about this Amiga version and since I own the label, I'd like to know more about it.
Just to understand what is this label that has arrived to me... :-)
Ciao!
Alex
