Input devices

Devices used to point, indicate or input text, coordinates or data to computer. The first such devices were keyboards and, for coordinates, light pens. In 1980s mice became popular. But mouse is not the only option - some stylus-based tablets or touch screens may be used. Also keyboard may be not simple alphanumeric, but e.g. programmable keyboard for quick automation of common tasks in embedded system.

Genius EasyPen  
Manufactured by: Genius

Type: Tablet with stylus
Interface: COM Serial port
Information: These graphic tablets were popular in 1990s, when they became affordable by average customer not being a graphics studio. Unfortunately it was cheaper by the cost of poor pressure detection and small area.
This tablet, when plugged in, can operate like a mouse or can be configured with driver.

It was bought in Germany. In a box, there is a print of an e-mail sent in 1999 about incompatibility with Windows 98. Genius (KYE Systems Europe) recommended running GTEST.COM DOS tool. I tested it in Win95 and it works.
