Wow, LMK when you get a PCI audio Interface (like 2496) to work via pass-thru, this would finally make a full working DAW a reality; currently all my "Virtual DAWs" do not perform with "real hardware"

Mostly that should work out of the box, maybe if the cards do Bus Mastering or some other funky PCI functions I don't fully understand it would need a few mods, but the cards do not have option ROMs or I2C busses that require firmware( OpenBIOS ) level mods.

Mostly the OS's runtime drivers for Audio cards are going to take care of everything for you.

Had you ever tried to pass a PCI audio card to qemu-system-ppc? It would likely help is a I finally track down the issue with OS 9 freezing on access to the 2nd CPU, but I've got a pretty good idea what the issue is now, just need time to go back over my work and make sure the interrupt-parent is routed through Uni-North and not directly to Mac-io interrupt-controler.

After an extensive amount of modifying OpenBIOS and a few mods to qemu I was able to get PCI Passthrough of a GeForce 7800GT PCI-E card to work with Mac OS X Leopard 10.5.8.

Mostly everything is untested and there are a lot of bugs wot work out, but QE/CI are reported as working and I was able to confirm the ripple effect in Widgets does work.

Due to my motherboard having issues with passing a USB keyboard to the guest I have largely not been able to test 3D gaming, but I'll get those issues sorted over time as I have it.

This opens the door for much better graphics performance in emulation, I've also started work on Geforce 3 emulation and 3dfx voodoo2 emulation, but a host system is going to have to be 20x faster than the fastest systems we have today before 3D acceleration like OpenGL in hardware is going to be anything but a slide show even if I complete that much of GeForce 3 emulation.

Turns out that 3D acceleration on an emulated GPU is one of the most taxing things you can do even on a modern host CPU. Without drivers to offload OpenGL calls to the host system you are stuck with a slide show. That's why work on PCI Passthrough is vital to emulation of PPC systems.

is there traces of ADB still on the mobo? maybe we can solder a ADB cable to that and then use WOMBAT to convert back to usb

There's a novel based on this business (TekServe) that I read a few years ago. It's called Laserwriter II. Here's my review of that novel if you're interested:

No problem. Much obliged.

Hopefully this ”404 Not Found" situation is only temporary.
Have checked it just now and two hours ago and still reporting same.

In the meantime, you might try the Hotline server…

Apologies for any inconvenience. 

Given the recent problems (hacked) with the Internet Archive…
may I suggest you try “our” download to see if you fare better?

Try this: http://macos9lives.com/downloads
and opt for the second listed download.

"404 Not Found" for all download links

It does take a bit of time (and effort) to navigate this site but as you become more familiar with it… even as it can be a bit quirky — there are a many absolute mountains of info and insight(s) to be had from such effort.

Have you recently changed any (even seemingly minute) preferences for Adobe Acrobat or Mosaic?

Whatever the case, I’d possibly use the backup drive (or restore) it’s content to your primary drive AFTER backing up everything that’s currently on your primary drive, so that work files or saved files (and some applications) could then be moved back to the “new” primary as needed.

You might also consider allocating more available memory (RE: the Type 2 error) for use by Mosaic, etc.

And then there’s always trashing related preferences.

Hope you get it worked out… if you’ve not done so already.

If the following link works for you, I’d very strongly suggest a read of this NY Times article about David Lerner (and especially all of the comments there too). Sounds like a much more personal and friendlier precursor to what some of us know as the “Apple Store”. (Only muy much better.)

Or, brief Wikipedia info here:

Wonder if DieHard knew or ever met this guy?

And I think maybe David Lerner had some of the same spirit that some of us here often exhibit?
