Dammit, I saw "PPC board" and assumed they meant board for an A2000, 3000 or 4000 or even 1200.

tl;dr came here was disappoint
Back away from the EU-SSR!

This is great news! Well done, it gives us even more options :D

You could always ask what programs works and what do not under the regular ppc32 Linux with the FPU instructions emulated to get an idea .

Working include
Webrowsers Qupzilla and Midori .
Libreoffice

Trapping direct FPU instructions would be a fraction of the speed of direct FPU support. Using the IEEE math libraries would be much faster (maybe half the speed of direct FPU use). Are developers going to compile for an incompatible FPU? It is sad that A-Eon is this desperate to keep PPC alive and affordable. Now PPC will not only be incompatible with the 68k and Amiga custom chips but also the existing PPC platform. The new board is too weak and incompatible to appeal to the classes and too incompatible and expensive to appeal to the masses. Full speed ahead with incompatible embedded PPC processors though :(.

IF you were posting on a Linux forum, this would be valid.
So, the question then becomes, what programs will run under Amiga OS and its derivatives without re-compilation?

I am referring to what runs under normal Linux PPC32 (Ubuntu 12.04) on the Tabor board.
Not the Debian 8 powerpcSPE.
So many of the regular powerpc32 binaries work with emulated FPU handled by the kernel without having to be recompiled .
The ones that do not would include Firefox and Mplayer.
Iceweasel work under Debian 8 powerpc32 .
So  one could expect many AmigaOS powrepc binaries might also work
once the emulation was implemented.

Just booted AROS powerpc hosted under Debian 8 PPCSPE on Tabor.

1.2 Ghz in 2015/2016? .

A 2014 Intel cpu:

Ok, well, not 1,2 but 1,3 only; not big difference
There is even 2015 intel chips with mere 1,4



*I know GHZ says nothing to compare different cpu power. i only respond at the (contempt)question quoted

You really want to push the Linux argument, but AROS is the only NG OS that can run under a Linux kernel and FPU trapping/emulation under OS4 will still incur a performance penalty (on an already relatively slow cpu).

Linux is the only OS that I can speak about :) .
You need to forgive yourself for being so sure that the CPU would from the T series. If you need to bang your head against something find a wall not another person .

Hooray more fragmentation in the Amiga market!  :(


How else could they justify high prices on technology that is a decade old?

In spite of the obvious concerns, I'd still prefer to see OS4 running on this before making any kind of judegement on it's abilty to run current software well.

It's possible that software like OxyPatcher/CyberPatcher/MuRedox for the 68k could keep the PPC FPU instructions from trapping but it is still a poor choice of processors which makes Amiga support, development and keeping compatibility more difficult. Emulation is faster than trapping so PPC emulation on an i7 would have even more of an advantage in performance and price.

That is assuming that running incompatible FPU opcodes will even trap (I don't have any idea whether it will or not).

Otherwise you're looking at recompiling when loading anyway, which if you're doing that you really might as well just switch to x64.

It's hot, slow and power hungry, so hopefully not.

You can't install 64 bit windows on it because of a crippled UEFI. They make the excuse that with 2gb you don't need 64 bit, but there are other benefits to running x64 code. They destroy their own argument by selling a 64 bit Linux version with only 1gb of ram.

I'm not sure what point you're trying to make, but it's not the type of cpu you even want to compare against. If it beats you then you're in real trouble and there is no kudos in beating it.
