Of the hundreds of potential softwares that I programmed I only currently have 1 official copyright. That wasn't even for the PC. It was for a TI83 smart calculator. However it wasn't that good. It actually changed the smart calculator into a time keeper. The clock was good for a while however with time it has errors crept in. However for maybe a week it was off by a second! It uses complex extrapolation mathematics to keep track of time. That is the current copyright for Texas Instrument company that I program their calculator.

Now I am seeking my very second copyright for the PC. It is actually small however useful. However the evaluation period is long. It could take up to a year depending on the volume of copyrights being asked.
