So many great (and bad) things: The Aminet repository. AREXX language. Directory Opus utility customizable file manager. Ability to sync w/ TVs. Hundreds of rich assembler coded video, audio, and graphics Demos of international origin. Cinemaware games. NewTek DigiPaint. Diga telecomm tool. Miami TCP/IP (I helped H.K. to get PPP working with NT Server). Unixy and open source tools available. Lattice C. Very capable multi-tasking. Hardware accelerators, FPU, SCSI boards. Dragging dropdown virtual screens. A single fixed root vector for OS (I no longer remember why important but the obvious), Logical Volumes and automatic mount requesters; good for small storage systems as the system knows to search and otherwise ask you to insert the correct disk, data or program. Dungeon Master. FA-18. Music Tracker and mods. Good enough quality sound. Again Directory Opus and Im sure I missed a lot.
