| The Amiga 1000, released by Commodore in 1985, was the first model in the Amiga line of personal computers. It was powered by a Motorola 68000 processor running at around 7.16 MHz (NTSC) or 7.09 MHz (PAL), and came with 256 KB of RAM, which could be expanded internally to 512 KB and further via external memory expansions. One of its unique features was that it did not have its operating system in ROM. Instead, the “Kickstart” portion of AmigaOS had to be loaded from a floppy disk into a special 256 KB RAM area on each boot. This allowed updates to the OS without replacing hardware, but made the startup process slower compared to later Amiga models that had Kickstart in ROM. The system used the Original Chip Set (OCS), which supported advanced graphics and audio capabilities for the time, including multiple display resolutions, up to 4096 colors in Hold-And-Modify (HAM) mode, and four-channel stereo sound. The case design was distinctive and allowed the keyboard to be stored underneath the main unit. The Amiga 1000 also featured composite video out, separate RGB and monochrome outputs, and a variety of expansion ports, including external floppy and memory ports. Some versions also included a slot for a Zorro expansion board. The Amiga 1000 established the technical foundation for the entire Amiga family and was praised for its multimedia capabilities and multitasking operating system, even though it was eventually overshadowed by more cost-effective and integrated models like the Amiga 500. |
