What has happened to KeyStone Professional, Keystone 99 and KeyStone 2000?
KeyStone Professional was designed for Windows 3.11 and was modified slightly in 1997 to operate in Windows 95 and Windows 98. The program was completely rewritten in 1999, was renamed KeyStone 99 and was made available last summer. As the Millennium date approached it was considered prudent to rename it KeyStone 2000. Due to confusion over whether the KeyStone product included voice recognition it was decided to establish two new product names: KeyStone SpeechMaster and KeyStone ScreenSpeaker, supplied with and without DNS voice recognition respectively. Some of our existing leaflets still refer to KeyStone 2000.
