PowerPC Liberation

This post has nothing to do with PowerPC

by zen

Over the last few months I've had a bit of an X99 obsession, and to the point that I built two systems. For those who don't know, X99 is a chipset for high end i7 and Xeon systems from the later part of the Haswell generation. Haswell-EP to be specific, which uses DDR4 memory. What originally attracted me to the platform is that these days it's the most cores per dollar that money can buy.

Like I already mentioned, I built two X99 rigs last fall, and I'm really loving them as both workstations and gaming machines. Here are the specs of the two rigs.

Main rig:

-Intel Xeon E5 2670 v3 12C/24T Haswell-EP w/Cooler Master Hyper 212 BE

-32GB 2133MHz DDR4 RAM (4x 8GB quad channel Corsair Vengence 3200 CL16)

-Huananzhi X99-F8 Gaming ATX motherboard

-ASUS RTX 3060 Dual V2 OC 12GB GDDR6

-Seasonic Focus GM-550 80 Plus Gold semi-modular power supply

-WD Black SN750 500GB PCIe 3.0 NVMe SSD

-WD Blue 2TB 2.5" SATA SSD

-WD Black 4TB 3.5" SATA HDD

-3x 120mm intake & 3x 120mm exhaust fans (Arctic)

-Cooler Master Masterbox Q500L ATX case

-Dell Ultrasharp U2415 24.1" IPS 16:10 @ 1920x1200

Secondary rig:

-Intel Xeon E5 2640 v3 8C/16T Haswell-EP w/Cooler Master Hyper 212 BE

-32GB 1866MHz Micron DDR4 (4x 8GB quad channel)

-Machinist X99-RS9 mATX motherboard

-Gigabyte GTX 1650 Super OC 4GB GDDR6

-EVGA 450 BR 80 Plus Bronze power supply

-Samsung 870 EVO 250GB 2.5" SATA SSD

-Crucial MX500 250GB 2.5" SATA SSD

-WD Blue 4TB 3.5" SATA HDD

-4x Arctic P12 PWM 120mm case fans

-Cooler Master Masterbox Q300L mATX case

-Dell Ultrasharp U2415 24.1" IPS 16:10 @ 1920x1200

Gratitude

by fiftysixk

I am sure most of you have heard about the news regarding TenFourFox and Classilla. If you have not here is a link to what I am talking about,
https://tenfourfox.blogspot.com/2020/04/the-end-of-tenfourfox-and-what-ive.html.

Reading this has made me look back over my PowerPC Mac experience. I am left feeling extremely grateful. Prior to my experiences with post Leopard PowerPC Masc I had only dabbled with Ubuntu on x86 and amd64 machines here and there. Running Debian Jessie and Wheezy on PowerPC Macs is what really gave my GNU/Linux skills a solid foundation. Having the ability to hop over to Tiger and/or Leopard and run TenFourFox at any given moment throughout all these years has been nothing short of amazing. One of, if not my most favorite periods of time in my technical journey has been the time spent on PowerPC Macs. TenFourFox was an absolutely integral part of this time.

Feel free to join me in the comments as I close by thanking Cameron Kaiser. We really appreciate the tireless, amazing work you have done for our community. Thank you for everything!

Still A Place For OS9

by Dronecatcher

For years I've used my Macs to produce and write music - generally favouring Propellerhead Reason for purely electronic pieces, Garageband where real instruments need to be recorded and often using both in combination.

The final step to a recording after mixing down is mastering to give it that extra zing and dynamics - for this I use SonicWORX which is an OS9 application.

Initially this would mean copying files to a thumbdrive, moving to an OS9 machine, processing then copying back but now I complete the process with VNC over Ethernet.

My OS9 machine for this task is my 800Mhz G4 iMac which sits in my desk corner keyboardless and mouseless.

I activate sharing between it and my Mac Pro, copy the files to be processed across, then use Chicken of the VNC to open up a remote session on the iMac.

The audio files are processed and copied back in the same manner they were sent.
So, there's still a place for OS9 and it's easy to include it in an OSX workflow.

Updating VLC To Play Youtube

by Dronecatcher

When VLC was last updated for PowerPC it was possible to play Youtube links copied into it - alas that ability has long since expired but you can bring it back with a few updated components.

This only applies to the last PPC iteration of VLC, version 2.0.10 and also requires the ever wonderful PPCMC (for latest security certificates and curl.)

The following code copied into Terminal will do the following:

Make a directory in VLC preferences for the latest security certificates

Delete the old Youtube lua script from VLC

Create a symlink in VLC preferences of the security certificates in PPCMC (this will update when PPCMC is updated)

Finally, using curl, copy the latest Youtube lua script into VLC

mkdir -p ~/Library/Preferences/org.videolan.vlc/ssl/certs

rm -f /Applications/VLC.app/Contents/MacOS/share/lua/playlist/youtube.luac

ln -s /Applications/PPCMC.app/certs/cacert.pem ~/Library/Preferences/org.videolan.vlc/ssl/certs/ca-certificates.crt

/Applications/PPCMC.app/bin/curl --insecure https://raw.githubusercontent.com/videolan/vlc/master/share/lua/playlist/youtube.lua -o /Applications/VLC.app/Contents/MacOS/share/lua/playlist/youtube.lua

From the download here extract the compact Youtube browser, Choob and the VLC scripts, VLSEE and VLLISTEN into Applications and create shortcuts in the dock (right hand side for VLSEE/VLLISTEN as they are scripts.) Open VLC and in Preferences - /Input/Codecs change the Preferred video resolution to Standard and close.

Opening Choob, browse to your chosen video, right click to copy the link then click the VLSEE dock shortcut - VLC will open and quickly stream the video - quit VLC when finished.If you want to stream audio only then do the same but with VLLISTEN.

Virtual PC and Ancient IDEs: Part 1 - Setting up Virtual PC

by fiftysixk

As mentioned in my previous post I have set up a 17 inch PowerBook G4 for Python, Objective-C and C++ development. One of my newfound time-sinks-that-brings-me-joy is setting up old Windows environments and installing very old IDEs. Examples include Visual C++ 6, Borland Delphi 7 and most recently PalmOS IDEs. I thought to myself, why not set up VirtualPC on my PowerBook and see how viable it would be? That is what I will cover here in this post. My ultimate goal is to set up a Windows 98 virtual PC and a Windows 2000 virtual PC then set up the IDEs on both virtual PCs. This will be a good way to compare performance between the two OSs under Microsoft Virtual PC.

Setting up Microsoft Virtual PC was fairly straight forward. I grabbed the Virtual PC 7.02 installer, 7.03 updater and the modified networking kext from the Macintosh Garden. Installing Virtual PC 7.02 and then updating it to version 7.03 was a simple software install. Now onto the Now onto the quirk. As pointed out at the Macintosh Garden, if Virtual PC is left as is on Mac OS Leopard, a kext icon will appear on your dock and bounce up and down while Virtual PC is running. I copied over the modified kext to /Library/Extensions as instructed. When I opened Virtual PC after doing this, Virtual PC said "The software necessary to run Virtual PC for Mac is either missing or is installed incorrectly" and then repaired itself, reverting the kext at /Library/Extensions back to its original state. I opened the original and the modified kexts to see if I could see any differences between the two. I found that the modified kext's info.plist had two extra lines.

Here is the original info.plist...

<plist version="1.0"> <dict> <key>CFBundleDevelopmentRegion</key> <string>English</string> <key>CFBundleExecutable</key> <string>VirtualPCNetworking1040</string> <key>CFBundleGetInfoString</key> <string>7.0.3 (070613), © 2005 Microsoft Corporation. All rights reserved.</string> <key>CFBundleIdentifier</key> <string>com.microsoft.VirtualPC.Networking.1040</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundleName</key> <string>Virtual PC Networking</string> <key>CFBundlePackageType</key> <string>KEXT</string> <key>CFBundleShortVersionString</key> <string>7.0.3</string> <key>CFBundleSignature</key> <string>????</string> <key>CFBundleVersion</key> <string>7.0.3</string> <key>OSBundleLibraries</key> <dict> <key>com.apple.kpi.bsd</key> <string>8.0.0b2</string> <key>com.apple.kpi.libkern</key> <string>8.0.0b2</string> <key>com.apple.kpi.mach</key> <string>8.0.0b2</string> </dict> </dict> </plist>

Here is the modified info.plist...

I opened the original kext in Text Wrangler, navigated to info.plist and added the two additional lines after the nested/inner dict block. Text Wrangler notified me that I did not have the privilege to modify this file. It asked for my password and saved the file after I authenticated. I was then able to open Virtual PC without being asked to repair my install or watch the white Lego jump up and down on the dock.

At this point I was able to make virtual PCs and install OSs on them. I made one for Windows 98 and Windows 2000. After the Windows installs completed, I installed the virtual PC additions for both virtual machines. This is done by clicking the PC menu then clicking the Install or Update Additions option.

This is a good stopping point. I wanted to share my experience with the kext quirk and what I had to do to fix it. As I set up the IDEs on these two virtual PCs I will share my findings and takes here.

As always, thank you for reading. Have fun!

TuneCatcher - A Youtube Audio Player

by Dronecatcher

I've often heard people on the MacRumors PowerPC forum say that they like to use Youtube for audio playback only - listening to albums or gigs etc so don't really require all the CPU intensive donkey work of playing video.

With that in mind I've cobbled together TuneCatcher and TuneStreamer - scripts that play audio only and save on all important CPU cycles.

Included in the install is Choob - a TenFourFoxBox Youtube browser preloaded with a vintage Nokia N90 user agent (hence the groovy app icon) which eschews all the usual Youtube script clutter and allows you to browse for videos quickly and efficiently.

Download and unzip the installer dmg - once mounted there is a choice of two installers. Youtube-dl is a requirement for this package, so if you have it installed as normal or with PPCMC, choose the appropriate installer.

Incidentally, PPCMC is a must have application for any PowerPC Mac - apart from it's core functionality it's also a Swiss Army Knife of essential tools including Python, youtube-dl, ffmpeg, curl and soon, ffplay all in one package without the usual fuss of needing X11 and Macports.

The installer will create a TubeAudio folder in ~/Music and place Choob, mplayer, TuneCatcher and TuneStreamer in /Applications.

Use Choob to browse for your desired clip, right click and Copy Link Location, then click on TuneCatcher in the dock (assuming you made a shortcut earlier.)
The link is passed to youtube-dl, the m4a audio file is downloaded and opened by MPlayer where the normal keyboard shortcuts apply for playback control.
When the clip is finished (or stopped) it is moved to ~/Music/TubeAudio/Archive.

Note, the m4a encoding used on Youtube is problematic to PowerPC Macs - without conversion they'll need to be played in either MPlayer or VLC.

If the Youtube clip you want to play is of a length unreasonable to download, choose TuneStreamer instead but be aware this will not keep a copy of the clip.
Also because of piping the stream via stdin the normal MPlayer controls aren't available.

Download is available here.

Download the G3 compatible version here. Unfortunately, mplayer for G3 doesn't accommodate streaming or playing m4a audio, so using TuneCatcher, a standard 360P video is downloaded which mplayer plays without processing the video.

MPlayer keyboard shortcuts for reference:

Pause/Play.....Space
Left/Right.......Back/Forward 10 seconds
Up/Down........Back/Forward 1 minute
9/0................Volume -/+
[ ].................Decrease/Increase playback speed by 10%
ESC...............Stop and quit
