Wasnt there something called Boxer Amiga 5000 project?
A chap called Mick Tinker designed an Amiga compatible machine based around hardware emulation of the classic chipset. The emulation could be tweaked for improved perfromance, and the motherboard featured all kinds of improvements/enhancements etc.
This would have been an ideal stepping stone between the A4000 and the Amiga One, but unfortunately it never got beyond the prototype stage, and I believe that people who put deposits on the Boxer got their fingers burned. All very nasty.
A shame is it was a great "nearly" machine in concept.
