So...a set of Acube designed schematics for a T2080 based board seems inevitable, and a board layout for a laptop seems likely.
While the laptop still needs more research&funding (battery,charging,case,display etc) I wonder if those schematics could be used by ACube to do a non retarded Tabor.......
Funny you thought of that, when I first mentioned the project to Bigfoot he said he'd like to have one to build a desktop or tower.
I don't see why the basic schematic couldn't be adapted.
But the gpu connections are set for an MXM video card and adapting the design to standard PCIe expansion slots would require reworking it a bit.
And I suppose a SFF board could still use MXM.
The layouts, of course, are specific to the laptop, with the case that has been chosen.
This cpu was one of the candidates I mentioned to Bill Buck when I peepared some initial specs for him.
Actually, it's the second most powerful, while still being relatively low cost.
So, in a curious way, this all moves forward even without Bill's involvement.
And, of course, we had feedback from posters here and on other Amiga forums (and in particular, I'd like to thank Andreas for allowing me to bounce ideas off him since we were discussing the MPC8610 and MPC8640/41 processors).
Once the schematics are made available, whatever anyone wants to do with them is their business, with the qualifier that creating board layouts with their multiple layers is actually a more complicated task than the initial schematics.
This will be (as far as I know) the first completely documented PPC design that our community will have access to, since some of the details of the Pegasos2 have never been released.
There is nothing to prevent Bill Buck or Paul Gentile (or Acube) from building a prototype based on this.
So, how about an Acube produced successor to the SAM460? Well, they ARE the first to have access to the schematics.
Prove to them (or someone else) that there is a market for it.
Bill Buck still has warm feelings for the ISA, but he didn't think it was a practical idea.
Still, I've always argued that we aren't bound by practicality.
Or I wouldn't have been searching all along for a like minded group of fanatics.
Luckily the Linux community still has a few.
It could even lead to some lingering interest in big endian PPC64.
