Select a IBM PC BASIC file from your machine and click Convert.
This page uses the BASFile.js module to convert encrypted and/or binary IBM PC BASIC program files to plain-text, with the option to convert any CP437 non-ASCII characters to UTF-8. The module is also built into the DiskImage.js command-line utility (in conjunction with the --normalize option) as well as the DX.js utility.
