@Plaz and Mark

Thanks for the info, I will contact both Davey and amiga.org, although I wouldllike to keep it here on AmigaWorld as this is where I sugested it and I generally prefer these forums (hence why I hang out here)

This is the perfect time to compete, competition bring lower prices and more choice both of which bring more people to the platform (Look at the apple clones for example). This would be a brilliant incentive for Eyetech to risk a bit of cash and shift production into high gear.
At the moment these boards would be more expensive than the A1-XE and uA1 but also offfer much more processing power, higher clock speeds and a wider, faster bus. These would not compete with the XE, or even the XC (If it exists, I haven't actually seen anything from eyetech on it, although they are amlost certainly working on something to succeed the XE)

The 90nm G5 consumes 45w per chip @ 2.0ghz IIRC, compare that to a P4 Prescott which consumes ~103w at 3.2Ghz (i think, it may be 3.0 ghz or 3.6ghz)
A while ago, before I did any major work on real world systems, when I was just a dreamer, such a system would have been my idea of perfect. Back then I wanted to design a whole new processor to use such a system with all new busses etc. and no legacy whatsoever, make my own custom chipsets, build them into my own purely SIMD (Think AltiVec) processor which would have mutliple cores and run in limmitlessly scalable SMP environments. I soon realised that it would be a mamoth effort for anyone to acheive such a design, just look at Intel's Itanium.
Such a design would be possible but would take so long to create, a lot of ASIC's would ahve to be designed and made, which would cost a not so small fortune. When I have learnt VHDL or Verilog (Haven't decided which yet) then amybe we could mess arround producing prototy[es of such a system, but I doubt it would ever reach a production stage, not that it amtters, it would be fun to do! One way to cheat would eb to license a lot of IP cores, for example USB, AGP, PCI-Ex etc.ad then just build your own modular system, but for that you need money, anyone know a good venture capitalist?

A mini-itx G5 board is a possibility as Apple have said they are coming out with a G5 iMac soon (IIRC the iMac base is slightly smaller than the mini-itx form factor but someone would have to measure one fore me), but such a board would be very dificult to make and woulld only be on the cards after an ATX or micro/flex-ATX board has been released.
I have been in touch with may about an Apple to A1 CPU slot adapter but I can't get the nessacery info without buying a board so that's another $3,900 that I would need. I will probably use the Apple CPU interface spec for the G3/G4 developed by XionIS. The G5 almost certainly has to have it's own CPU inferface as it would need more power and more pins, I haven't seen the insides of an Apple G5, if someone could send me a photo of the CPU slot I would be very grateful.
I spoke to Jens a while ago and he doens't want to *make* a board to compete with the A1 but I will ask both him and Elbox if they would stock such a board. If Eyetech were allowed to rebadge a board as their own they may sell i.
Someone from Hyperion has allready been in touch with me, I will reply as soon as I have had breakfast.
A toyed with the idea of a PowerPC upgrade for classic systems (1200's mainly). My idea was to use a Marvell Discovery III northbridge, a Marvell SATAII chip, an NEC USB 2.0 chip and a Texas Instruments Firewire 800 chip to make a tapdoor expansion for the A1200. The problem is I would need to either design an interface between the PCI-X slots on the Discovery III and the Tradpdoor slot. The best way to do this would be in VHDL or Verilog and an FPGA. I don't have any knowledge of VHDL or Verilog so I would be learning from scratch, whcihc I would be willing to do but would take time. In preperation for this I just got my hands on the Amiga Hardare Reference Book, all I need now is a PCI-X spec book such as http://www.amazon.co.uk/exec/obidos/ASIN/0201726823/ref=wl_s_3/ref=cm_mp_wli_/026-9823326-6748410?coliid=I3OVUKR07TSH24
I also thought about building a couple of Zorro slots in for legacy upgrades and then why not throw a AGP slot in using the same method Genesi did, a PCI-X to AGP converter, again I would be willing to try it but woukld need an AGP spec book such as http://www.amazon.co.uk/exec/obidos/ASIN/0201700697/ref=wl_s_3/ref=cm_mp_wli_/026-9823326-6748410?coliid=I1AQRO9P37A5O3
