Hmmmm. I remember that SOMETHING in the game console world from about, erm, 1994 used the PPC 602. It may never have seen the light of day, but I'm sure it wasn't the Apple/Bandai thing.
INTERESTING. The 602 was 64bit, and was the heart of the M2 add-on module to the 3D0.
602 was not a 64 bit processor in the sense that it could adress 64 bits of memory. It had a FPU that processed 64 bit data types though and I guess that's what the 3D0 blurb was all about.
The 602 user manual on IBM's website shows that the 602 was an entirely 32 bit architecture. It didn't execute 64 bit FPU ops in hardware:
In the 602, all double-precision arithmetic operations, floating-point load or store operations that involve double-precision operands that cannot be expressed as single precision values, and operations producing denormalized numbers are handled by emulation software. The 602 traps to an exception handler when it encounters these operands or operations.
I think I'll trust the user manuals and technical summaries before the 3DO press release. Certainly very strange.

I'll bet they were talking about a bus width somewhere in the processor... that was back in the days where some companies were claiming silly things about the "bitness" of their game systems.

Yes, that certainly rings a bell... interesting that it has only taken IBM another 11 years to finally get a 64-bit PowerPC back into game consoles.

The early 7400s were even pin combatible with the 750s. I could have stuck a 7400 G4 in the ZIF socket of my B&W G3.
Would that really work and where could i get one for my B&W?

Check it out. For $300 you can be at 1GHz.
