File talk:DEC VT100 terminal.jpg

The data displayed on the terminal is a file listing from a DEC RT-11 operating system disk, probably on a DEC RL-02 cartridge disk drive (10MB capacity, approximately 20000 disk blocks). There are two kernels on the disk: the RT-11 "Single Job" kernel (RT11SJ.SYS), and the RT-11 "Foreground/Background" kernel (RT11FB.SYS), which can execute two programs concurrently. The RL-02 was a massive disk drive for RT-11. A minimal RT-11 operating system setup could be created on a double-density 8-inch floppy disk (480 disk blocks [240kiB] after initialization). — Preceding unsigned comment was added by 192.100.51.131 (talk) 17:56, 25 September 2018 (UTC)
