=== Mac BinHex ===

When the [[Macintosh 128K]] was released in January 1984, the file upload problem still existed on CompuServe. In April, BinHex was ported to the Mac using [[MS BASIC for Macintosh]].{{sfn|Mann|1997}} The [[Macintosh File System]] had introduced the storage of files as a "[[resource fork]]" and "data fork", and the Macintosh port only supported encoding of files' data fork, meaning it could only be used for data files. Several newer versions were published during 1984, resulting in BinHex 3 which could encode both forks.

Yves Lempereur, author of the first [[Assembly language#Assembler|assembler]] for the Mac, MacASM, ported BinHex 3 to assembly language, increasing its speed a hundred-fold, and released it as BinHex 1.0.{{sfn|Lempereur|1997}}
