What did I do with a PowerPC today? I moved it (!), as part of reorganizing my work space. I am doing more and more work on my G5 AirQuad (I am porting the latest version my VE text editor to (n)curses, using the AirQuad as the development environment), and it was in a space in the room that made it quite an eye and neck strain to use for any extended period of time.
SO... I moved it into my main desk area and used the opportunity to swap my 30" Apple Cinema HD display from my G5 Dual 2.3 to my AirQuad. I then swapped another set of monitors, so that my G5 Dual 2.3 GHz uses my next best DVI monitor, a LaCie 324.
Here is what the work area looks like from the user (me!) perspective:
The two paired monitors are connected to my Mac Studio. The 30" Cinema HD display is connected to the AirQuad. The AirQuad keyboard and mouse are a vintage Logitech S530 set, wireless, and with wonderful key press feedback (for the keyboard) and hand feel (for the mouse, which has a satisfying heft to it). The Mac Studio keyboard is standard Apple stuff; its mouse is a recent Logi offer which is quite good.
You can also see the iSight camera that I have posted about to the lower right of the Cinema display, and the wonderfully large wired remote volume control for the system's speaker set.
Finally, just under the point where the two paired monitors meet in the middle, you can see a USB Zip drive, which is connected to my Mac Studio, and which provides the Mac end of the "SneakerNet" I often use to transfer files from my DOS machine to my Mac Studio (for archiving).
... and here is what it looks like from the back, as you walk into the room:
You can see the AirQuad to the left, and the Mac Studio to the right. The Mac Studio is sitting on its own box, which itself is sitting on a 1990s vintage Logitech subwoofer. It's speakers can be seen to the left and the right on the desk above the machine.
In the very foreground of the above photo you can see my 2008 Mac Pro, an 8 core Intel Xeon machine. It runs Snow Leopard, which it was delivered with, and High Sierra, which I slowly and painfully upgraded it to.
It is a "busy" space, but it works well.
