PPC Developers Board

I dont get it. I also dont get the point of UAE with PPC emulation to run OS4 - why emulate the old Amiga hardware when OS4 was made to not need it? Why bother with PPC on the MiniMig, when OS4 doesnt need it? (Hohum, does it even support ECS directly, or does it rely on the CVPPC?)

It should really be alot easier to hack OS4 to boot on PearPC and old Macs than to build new "old" PPC acc-boards. I'd guess it's even easier to build new proper PPC boards using modern chips, than to build old acc-boards.

Yes, 060's come at up to 100Mhz now

You have reference for this, other than slightly vapored CT60?

Freescale certainly has no clue about this, they sell full 060 at 50MHz and 60MHz, and have LC (broken FPU) and EC (broken FPU and MMU) available up to 75MHz.

Kolla, OS4 does need PPC to run.

What I meant is that OS4 doesnt need MiniMig :-)

Kolla, OS4 definitely needs more hardware capable of running it. Minimig could be one of those solutions.

OK?
Let's say you've made a MiniMig with PPC - now what?

After a PPC Minimig was created, we'd probably need to do some work to get OS4 working on it. After this, the OS4 h/w problem is solved.

So, let's ignore that there is no PCI or Zorro bus for gfx cards, no networking, no disk controller, and only glorious OCS for OS4 to display its 24bit icons on. Yay!

I'd say you have _a lot_ of work to do still. And after that again you have to make OS4 work on it. Why not just skip directly to "make OS4 work on it" and replace the hardware with something that exists already?

Grab an efika or something, it's a heck lot better starting point than the MiniMig!

More OS4 h/w means more users of OS4, which means more OS4 development. How hard is that to understand?

The hard bit is that I dont see the point in wasting time with OS4 for MiniMig. The point of MiniMig is to be able to run old amiga software. The point of OS4 was to move to PPC and get away from legacy hardware!

OS4 for classic is a nice treat for those of us with capable PPC cards in our amigas, but that's really all it is!
