A fine example of Apple's PowerMac G4 from year 2000. 450MHz, 1MB memory, 60GB hard drive, running Mac OS X 10.4 Tiger.
There is a ZIP-100 drive, but it does not seem to work. It didn't recognize the disk I inserted. Everything else (including DVD burn) is good.
Just the pictured tower and power cord. Use almost any IUSB keyboard./mouse and VGA or DVI monitor.
