A few of the things which are currently missing from this:
* Apple DOS, 1978-1983 * Apple SOS, 1980 (the Sophisticated Operating System for Apple III) * Apple ProDOS, 1983-1993 * MacPaint, 1984-1988 * MacWrite, 1984-1994 * MacTerminal, 1984-1987 * Apple GS/OS, 1988-1993 * Macintosh Portable, 1989-1991 * Apple Dylan, 1992-1995 (lives on as OpenDylan…) * Taligent, 1992-1998 * Apple Workgroup Server, 1993-2003 * Macintosh Application Environment, 1994-1998, a $549 software package which allowed running System 7 on Solaris and HP-UX * QuickTime VR - 1995-? …to my surprise, apparently still playable until Safari 12 in 2018 * MkLinux 1996-2002, a port of Linux to run under the Mach microkernel on PowerPC * Twentieth Anniversary Macintosh, 1997-1998 ps: anyone reading this who wants to open a github PR to add these things to the site, please do :)
