Thanks for all your help in replacing my trackball. It has served me well since 1987. I purchased it after seeing an advertisement in an engineering trade magazine. I was doing contract circuit design and PCB layout at the time and the mouse I was using was very difficult for making many of the precise movements needed. It was also difficult to get much work done in a short time because the mouse was so tedious and caused a lot of wrist ( and mental ) fatigue. I even tried an optical mouse and it was only a little better.

After receiving my Itac Systems trackball, I felt like I had stepped briefly into some sort of celestial glory. After getting the feel of the new device I was able to literally fly through my engineering designs and related CAD work. Now I could start to close the gap between how fast I could think and how fast I could translate thought into action. In 1989, when I took a job as a television systems design engineer at the NASA-Johnson Space Center in Houston, I took my trackball to work the first day. I told them I wanted that trackball instead of a mouse. They bought me one, and soon the other systems engineers and our circuit designers, technical writers and drafters all wanted one too. John our boss finally said, "OK get one for everyone who needs one".

Now I work as a technical manager at the University of Nebraska. I have an Itac Systems Mouse-track B-5xx9P at work and couldn't be without it. Thanks for all your hard work at Itac Systems, in producing the world's greatest computer pointing device.

I will return the old trackball to you under RMA#5633 as soon as I receive the replacement unit. Thanks again for all your help.
