Newton OS 1.0 was first released with the original MessagePad on August 3, 1993 and used the CalliGrapher handwriting recognition engine. Rapid releases of early patches were focused on stability. Version 1.1 added German language support in October 1993. Version 1.3 was initially released with the MessagePad 120 for the German market in October 1994, and then became available as a downloadable software update on January 30, 1995 for existing users of the MessagePad 100 and 110. It also added French support.
In December 1995, the MessagePad 120 became the first model to be upgradeable to Newton OS 2.0 through the replacement of a socketed ROM chip for US$109. Handwriting recognition was greatly improved and could recognize both printed and cursive script. Version 2.1 was the final public release in March 1997 and added grayscale support. The ROMs from Apple's eMate 300 and Schlumberger Watson were discovered to be version 2.2, but patched in software to identify as 2.1. The Newton product line was discontinued on February 27, 1998.
