Do you long for the days when your Mac would start with a smiling Mac logo and a row of INITs along the bottom of the screen? Or perhaps you miss watching a NeXT machine perform its initial memory scan? Pine no more for the past, because The Restart Page will transport you there. Choose from 17 Restart dialogs belonging to vintage versions of the Mac OS, Windows, NeXT's OPENSTEP, ProDOS (on the Apple IIgs), a developer build of Rhapsody, and others. Some sequences even include the old startup chimes.follow link
