What is an HR file?

An HR file is a raster graphic created for use on a Tandy TRS-80 computer. It contains an image that is exactly 640 pixels wide by 240 pixels tall. Some modern image viewers can still open HR files.

More Information

Tandy produced TRS-80 computers from 1977 to 1981. To allow their computer to display HR images, TRS-80 users needed to install the Grafyx expansion card or another suitable hardware upgrade.

NOTE: HR stands for "high-resolution."
