Acrobat Reader 1.0 for Macintosh, later for DOS and Windows 3.1. This was not available in single copies and was not initially free. After a while the IRS purchased a right to distribute Reader 1.0, effectively making it seem free to those who obtained it that way.
PDF version 1.0 supported.
Acrobat Exchange 1.0 (included PDFWriter printer driver and Acrobat Exchange application).
Acrobat Distiller 1.0. Created PDF from PostScript (no printer driver at this stage).
