Reproduction of PPC cards possible??

Sorry, but that is total #### ....

WarpUP needs an 68k, and an 68k-OS running on it.
Something that is impossible when you have no 68k (when you you look at an A4000), or just an 68ec20 (A1200).

So you would atleast need a new (PPC)-kernel with 68k-emu, somthing like MorphOS-0.x for example.

Emulating/recreating the PuP-API on such a beast should be much easier than doing it it for WuP.

-cleanly seperated 68k and PPC binaries instead of chaotic ext-hunks
-limited API instead of a PPC trying to do what it couldn't do (calling 68k-funcs that is)

So anybody still claiming that WuP was a 1st step into the direction of an PPC-native OS is in serious need for a clue.

How should WuP be made aware of the new card, when it can't run due to the lack of an 68k ....

There was no 68k on the AmiJOE, and a pairing between the the 68ec20 and an G3 would have served nothing excet comical purposes ....

Both PuP and WuP heavily rely on the dual-CPU setup (a setup that allready crippled the 603/4-CPUs) and the abilty to complety take over the PPC, which is hardly possible when you also need it to emulate the missing 68k.

@Argus

It IS crippled compared to what the same CPU achieved in pure PPC-systems (early PPC-Macs, BeBox).

Sharing RAM between 2 incompatible CPUs and disabling L2-cache sure do no good....

The point is that there is absolutly no point to design a dual-CPU card with a G3/4 and an 68k, and that a pure PPC-cardwould require a real PPC-OS (and not those oddities known as PuP/WuP).
