Support for FireWire 400 and FireWire 800.500 milliamperes (mA) at 5 V are available for each USB 2.0 port, for a total of1.5 amperesFireWire Specifications.Each rear port is on a separate 480 megabit-per-second(Mbps) USBchannel.Support for Universal Serial Bus (USB) 2.0 and 1.1.Here are the specifications for a 1.8 GHz dual processor Power Mac built in early 2004 (this data is directly from the “User’s Manual” Apple provided with the computer): Later models were equipped with cooling systems made by Panasonic which were more reliable). Some of the dual processor 2.5 GHz and all the dual 2.7 GHz processors were liquid cooled (the early Delphi produced cooling systems were buggy. In 2005, there was a shift from dual processors to dual core processors, and a quad core 2.5 GHz processors was also introduced. The processors were made by IBM and during the production run they created single processors at 1.6 GHz and 1.8 GHz, and dual core processors ranging from 1.8 GHz to 2.7 GHz. The Power Mac G5 is designed for an industrial/commercial customer: labs, schools, photo/movie editing, graphic rendering, desktop publishing, engineering, etc. The Power Mac was released in June of 2003 and ended its run in August of 2006, when Apple switched to Intel processors. From a design and engineering standpoint, even by today’s standards, these are amazing machines. After doing a few Google searches, I ran across some ads for Power Macs, and the more I studied them, the more I knew I wanted a Power Mac G5 for myself. I wanted to stay with Apple, but because of my limited budget for this project, a new or nearly new refurbished Apple computer would be out of the question. Problem solved, now all I had to do was figure out what I was going to use for my second computer. Adding to this is the extra bonus of having the power of the extra computer. I knew I could run two computers from one keyboard and mouse by using software like Teleport, which would also allow me to cut and paste, and drag files between the computers seamlessly. My work-around was to add another computer. My iMac lacks a port for an additional monitor, and though the 24″ screen is big, it does not compare to the two monitor systems I was used to. Sadly, after using the iMac for a while, I missed having two monitors like I used on my Windows computer I liked the convenience of the expanded desktop and it made working on projects much easier. The only thing I have done to it has been to max out the memory to 4 gigs, and keep the operating system current. I still have it and it has been a terrific machine. In 2008, I switched from a Windows driven PC to an Apple computer.
