3) I'd like to see an Amiga make use of the same connector the Mac users. There's probably licensing issues involved to do this however, that may prove limiting. But, as Mac users discard their processors it'd be cool to pick up a used one for the Amiga. Consequently, you could make a faster G5 card and sell to Mac and Amiga users both.. Probably never happen but cool.

I actually sent an email to PowerLogix on the same subject, but never received a reply. If a few Amigans would send similar emails, that might get their curiosity started on looking into the Amiga market as well.

Though I haven't looked at the PPC970 Eval board in depth, what does it lack in regards to a normal mobo configuration/chipset?

The chipset used by the Momentum evaluation boards which this design will be based on is the IBM CPC925, this is actually ready for prouction round about now, compared to the Articia I which is still just a dream in Mai's eyes as far as I can tell from talking to them and considering that the P and Sa haven't been released yet and again don't seem to be likely to be ready any time soon. I was never considering building my own northbridge, at least not for a long time as I simply don't have the skills to do that at the moment, I was simply pointing out what would be required for a modular PCI-Express design.
Different form factor boards would not be dificult once the first has been completed, Eyetech have shown this with the speed at which they completed the MicroA1, despite having to wire RAM and a graphics card in!
The classic upgrade certainly has a questionable market at best and so wouldneed more research but wouldn't be that much work over a standard G3/G4 board, the hardest bit would be the Trapdoor to PCI-X interface, which I would probably need Jens Schofeild's help with.
Getting Apple pinouts probably does require licensing and I doubt they would license them to a competeing motherboard manufacturer but an Apple to Mai converter would be a more realistic optcion, that way wither connector can be used and cheaper more common place Apple CPU modules can be used on our A1 boards. I have no idea how the G5 CPU's are connected as I have never seen one of the machines in person nor any clsoe up photos, if someone could take some or point some out to me I would be gratefull. Maybe I will look through Apple's technical/developer info and service manuals when I get home
I once treid talking to KMOS and Amiga Inc. about getting AOS4 on Macs and whether it was the manufacturer taht needed to licesnse it or anyone could taht could produce a dongle but never got a resonse. Maye someone from Hyperion could answer this for me. I will email Thomas Freien when I get back to see if he can answer this for me.
