Damn you PearPC, damn you!

They are currently working on version 7 that will be far better than 6 (direct video card usage)

nt is NOT unix.

No but some of the concepts that inspired it were founded in Unix. However you are right, NT is not in any way, shape, or form Unix by any stretch.

No, the concepts that inspired NT came from VMS, not Unix. The system structure is quite different from Unix. All of the Unix-like stuff was tacked on later. For that matter, so was the Windows-like stuff - it wasn't until NT 4 that the GUI subsystem was integrated into the kernel, to the extent that such a concept has meaning in NT.

Given the circumstances I think we can forgive them for that. The circumstances on the Mac being in part the G5. VPC was previously optimized using the optional little-endian addressing mode of the Motorola PPC chips. The IBM G5 doesn't have that mode, and VPC without it was bog slow. You would have to add something like direct video card access just to catch up with the performance of VPC on the G4. Figuring out how to do that would take time, hence the delays.

With any luck they will be able to carry this video knowledge over to the Windows version of VPC and really give it a boost too.

Version 7 is still under BETA (VPN)

NT is not a UNIX System because it UNIX System are stable and not buggy...NT is a Microsoft's own UNIX Clone operting core aka Kernel which they call it "stable and secure"

also they were waiting for sp2 final release for implementing it on their "Virtual PC 7 with Windows XP Product"

I don't think the lack of this addressing mode is a big thing, since they only need to flip the bits, and this is 1-2 cycles. The lack of this mode only prevents it from running, and the 6.1.2 (I think) update takes care of that.
