Thank you for finally getting that going! Were you going with the original Cyrix or the Pentium MMX?

My understanding is that this is standard behavior. It can recognize how much is installed, but cant use it. Hence Mac OS "using" half a gig.

Did the Valkyrie even do 2d acceleration, wasnt it just a fancy frame buffer? The ole ATI Rages weren't the fanciest but I always found then to be pretty speedy 2d-wise.

Yeah, im pretty sure it should show a area for the USB bus up near the ATA and SCSI bus areas if it sees a USB bus. It must be able to identify it as a USB card but cant use it.

Just chiming in to the say I'm having the same issues on my PCC Powerbase. This is with a Silicon Image USB2.0 card too (that I'm 99% worked in OS 9 on a G4, as 1.1 obviously).

I apologize, didnt mean to double post.

Would a hardware solution between the 68060 and the rest of the 040/030-based machine be something the Amiga accelerators used. Some sort of compatibility layer.

Was going to say the same, but the previous G3 versus G4 discussion was already linked.

Much akin to Intel Macs, or PowerPC macs during the transition to the next. Why would anyone spend time developing for a dead platform. I'm impressed with the numbers and then much less so. Clock for clock, I was reading that an 060 should be outperforming an 040 by 2 or even 3 times. There...

Im pretty sure no one is using an 040-powered machine for productivity anymore. Unless its in some industrial equipment or something, in which case its very doubtful you'll be throwing some weird third-party upgrade into it. Especially doubtful its a Mac too, anyway. I'm actually excited...

The true question is: How well does it play Doom... theoretically?

Take that Amiga nerds./s I was just saying to myself there's nothing interesting going on in the classic Mac sphere at the moment. Thank you for this. Neat!

I don't think I've ever come across an Apple ZIF with a fixed anything.

I think the Turbo wasnt a real upgrade, so I doubt its a different pinout. They just did some driver trickery with it. I think that's the right one i'm thinking of.

Ive never seen that style, clearly marked as a 750fx too with dip switches. Maybe a weird Japanese brand one.

No, it works fine on mine which had the resistor based overclock.

I agree. I always heard, back in the day when I would send mine in to Apple to get "fixed", that it was only the smaller 17" that suffered from this. I always wanted that huge 21, though. Nice documentation too.

I'm listening in as this is a interesting topic. Did the secondary CPU have to be "MPe" or multiprocessor enabled, akin to Daystars marketing at the time?

I believe that model would need an LC-PDS video card, which personally I've found to be rare and few and far between. Plus, since most were aimed at 68030-era machines, I imagine they're probably not much faster than the 5200s native video. I might be wrong though, but hopefully someone with...
