The speaker jack on a real Apple II has +5v on one pin and the other pin is the sound output from TTL logic routed thru a bunch of passives. I don't know what the IIe card's output looks like.

Other than R899, which appears to be a pull up resistor. That may be a show stopper from using this pin as-is.

What does the circuit look like between the PDS slot pin and the audio output? Its likely it attenuates the 5V TTL signal down to line level before mixing it into the main audio output.

Kinda stumbled across a utility suite that came with the Columbia AppleTalk Package: https://github.com/mabam/CAP/tree/master/contrib/AufsTools

The HFS MacFUSE file system would be a good starting point to see how to natively integrate resource forks and FinderInfo into the macOS port of afpfs_ng. https://github.com/thejoelpatrol/fusehfs Other platforms shouldn't attempt to do this. The existing method of throwing the resource fork...

ProDOS used 7 bits to store the date, but intentionally limited the date field to 00-99. GS/OS expands this further, but the onboard clock is still limited. https://prodos8.com/docs/technote/28/

MMX CPUs require split voltage supply. They just won't work in a standard Socket 5 motherboard hence why Pentium Overdrive MMX CPUs exist (they have the proper VRM are part of the chip).

Looking at period documents, this would sold under APDA #M7047/B. I also found references back in 1989 for an earlier document called "Script Manager Developer's Package" under APDA #M7047. This is likely an earlier revision of the document going by the order number and might also cover...

Yes, this machine came standard with a SuperDrive. I'm not surprised a consumable would go missing after all these years.

Of note, my Late 2003 15in Powerbook G4 1.25Ghz (first gen AlBook) came with a blank Apple branded DVD-R disc. I have to pull the box down the next time I'm in the attic.

megatron is part of Netatalk 2.x and was removed from newer versions due build issues. Don't know how it would have appeared on a macOS machine!

The STB Horizon+ is a generic Cirrus Logic CL-GD5430 based card. That happens to be the same chipset hypervisors like QEMU have support for.

IIRC, if the FinderInfo is entirely null bytes (or set as such), the OS will hide the com.apple.FinderInfo extended attribute from xattr and the C functions. The extended attribute itself is a system abstraction as stated previously.

As mentioned before, this is common with Apple II files stored on HFS volumes as they usually don't have resource forks (only GS/OS supported them), but still needed to store ProDOS filetype/auxtype information. Also many cross platform document formats are data fork only, so rely on FinderInfo...

Eck, I meant to say 2 bytes (16 bits).... whoops.
