MemoPad

Memo Pad under Windows displays the files using the same font used on the Atari 8-bit computers. Memo Pad is named after the memo pad found on the Atari 400 and 800 computers. It was written to allow Windows users to read ATASCII files. Memo Pad displays the files using the same font used on the Atari 8-bit computers.

Memo Pad can also display ASCII files that contain a common end-of-line character. The common end-of-line characters are CR+LF used in Windows and DOS files, CR used in Apple II and MacOS 9 and earlier files, and LF used in UNIX files.

At this time Memo Pad does not support editing and is mainly for viewing files but it does have the ability to convert end-of-line characters and re-save the files.
