USB To PS2 Adapters
PS/2 ports are usually used to connect keyboards and mice to personal computers. Their small size makes it impossible to handle extremely large amounts of data at one time; however, they are perfectly able to deal with the relatively low stream of activity created by most input devices. However, because they are so rarely used with devices other than the mouse and keyboard, there are usually only one or at most two of them provided on any given computer.
This is an easy limitation to fix, if you want to. PS/2 adapters are easy to find. They connect to your computer through the USB port and allow you to connect one, or even multiple keyboards and mice to your computer. Both sets of keyboards and mice can then be accessed simultaneously.
There are plenty of different PS/2 adapters to be found here at Byte Runner Technologies. One of the most frequently used is the UC451. This is a simple cord; it is easy to install, requires no additional software, hardware, or additional power supply, and is compatible with all system specifications including Macintosh and Windows operating systems. It adds an additional two PS/2 ports to your repertoire.
The UC451 is only one of the many different adapters that we stock here at Byte Runner Technologies. There are plenty of others, including a fair number of infrared adapters, distinctive ring routers, VGA splitters, and KVM switches--among many others. Each of these products comes with free technical support, a year-long warranty, and a 30 day money back guarantee.
