CompuServe RLE

CompuServe RLE is a bi-level image format that was used by the CompuServe on-line service. In some ways, it is the predecessor of GIF.

The image dimensions are either 128×96 or 256×192. Images are RLE-compressed.

Files consist entirely of ASCII characters, though some are control characters.
