Hi all

I never looked into this before on my Apple Cube, but just for the sake of information: ARC 1.0.1, 1.0.2, 1.0.3. installs on PPC Mac. All later releases exclude PPC macs.

Hello, first post for me... I have searched, but getting a little lost!

I've managed to get my Powerbook 'Aluminium' 15 inch 1Ghz booting into Mac OS9 using the open firmware hack detailed below. I have everything working, except there's no audio device (so no sound, internal or external). Is there anything I can do to get the sound working? The post I followed was years old, so I'm hoping there's a better way to do this... or possible updated audio drivers?

Any help very much appreciated:-)

For what it's worth (and you probably know this already) there are a few pages about Inter-Poll here:

Thanks for sharing the Inter-Poll reference. This is the information I was looking for. Very useful information.

Thank you @aBc for responding. I have been working my way through some of that information. Of course I was kind of hoping there might be an answer along the lines of, "90% of the time it such and such dohickus that is bent out of shape." But reality tends more along the lines of fiddling around with a half dozen or so minor hard to see, hard to get right tweeks that are needed to get things working.

I did notice the pictures until I logged in to reply. What is the logic behind requiring a login before displaying pictures? In any event thanks for the suggestions and the pictures.

The drive is working fine and is the one from this PB G4. This unit was a lucky and rare find. From what I can tell from files on the hard drive it was in service for about 6 months before being stuck on a shelf and abandoned. The battery was stone cold dead, but took a full charge having ~80 cycles on it and now with a full charge it gives ~4 hours run time. There is not a scratch or dent on it. There was a missing keycap and the unit was filthy (from sitting for years in an attic?) And now I have been using daily.

Ultra-Fast SCSI (narrow FAST20), with theoretical speeds up to 20 MB/s. However, real-world performance tends to be around:

Read speeds up to ~18 MB/s

Write speeds up to ~11 MB/s

thats even faster than BlueSCSI v2
Supports Ultra‑SCSI FAST20 sync up to 18 MB/s (with overclock)

Pre-release of firmware for BlueSCSIv2 from July 2025 opens up similar opportunities. There is information about the tests here.

i love it, after restoring apple floppy drives, my tibooks need to have their cdroms serviced as well,

they all sort of work mechanically

No dings or external dents in the outer case, especially near the right internal mounting point or along the front of the case where drive ejects? (Had one here with a fairly severe right corner dent that changed the position of that right front mount just enough to interfere with eject.)



Other than that, a very sparse light coating of lithium grease applied to the drive’s internal metal pivot arms and other moving parts can do wonders.

If the keyboard being properly installed interferes -  that suggests the drive is somehow “higher” or otherwise out of normal position (from other possible damage?) for some unknown reason or another.

Is it an original optical drive or a replacement of some sort?

All red-dotted tabs correct and no other obstructions (rubber pads, etc.) to interfere here on the bottom side of the top?

Thanks for the link, J. Great to see (and hear) the “old man” being creative… even if he’s in his pajamas originating from the new Inter-dimensional Retirement Center for Forum Masters.

And yes, an added ripping guitar solo break might have just set the video completely on f-f-fire!

Of course, I’m mostly kidding here. But honestly, big thumbs up!

You owe us a guitar solo, DieHard!
