Hello
9 years ago I created PC + PowerPC hybrid machine, based on YARC SMP PowerPC 601 cards and TAOS AMP (pre-cursor of Intent / AmigaDE). I combined ordinary Dell PC with 2 Dual CPU 601 cards.
Perhaps if AmigaOne G4 Dual CPU card is out, I will combine it with Quad P4 Xeon inside CalPC case. For connection perhaps Myriad, Dolphin or SCSI card or others. I hope to run AmigaDE AMP (Assymetric Multi Processing) on top of such machines.
Another way is putting Omnicluster Pentium 3 cards inside AmigaOne Dual G4 machine. It is also possible to use TotalImpact Quad G4 with PC or AmigaOne.
