Commodore's first member of the Amiga line, shown here, launched for US$1295 with a base unit, a keyboard, and a mouse. The base unit included 256KB RAM and an 880KB floppy drive. This system shipped under the sole name "Amiga" at first, but Commodore rechristened the machine the Amiga 1000 after the launch of the Amiga 500 in 1987.
The Amiga series ran a 32-bit preemptive multitasking graphical operating system known as AmigaOS. However, AmigaOS also included a command shell called AmigaDOS for more-powerful keyboard-based input.
