Newton OS

Newton OS was an operating system developed by Apple Computer for Newton mobile devices, such as the MessagePad series and the eMate 300. It was first released with the original MessagePad in August 1993. Version 2.1 was the final release in March 1997 and the product line was discontinued on February 27, 1998.

Some users claimed that Newton OS was a stripped-down tablet version of classic Mac OS but Apple stated that it is not.
