The A2000 ROM chip is also fully compatible with the Amiga 500 and 500+, which were both designed as economical all-in-one solutions with an integrated keyboard resembling the Commodore 64C/Commodore 128. More information on the Amiga 1000 can be found at OLD-COMPUTERS.COM, the Amiga Hardware Database, and the Amiga Interactive Guide.Ī2000: The first 'big box' Amiga, this advanced the design of the Amiga 1000 by offering more traditional card slots (Zorro 2 for Amiga expansion cards, a CPU expansion slot, a video expansion slot, and IBM XT slots intended for use with Commodore's Bridgeboard PC compatibility card) instead of a single edge connector, updated custom chips, 512KB of chip RAM standard (on the motherboard, later upgraded to 1MB), three internal floppy bays (two 3.5', one 5.25'), and Kickstart in ROM (originally 1.2, later 1.3 and 2.04). This tune (amplified by 10dB, as the actual tune is rather quiet) can be heard in WAV (53K), MP3 (20K), and 8SVX (105K) formats. Among its other unique features (such as the keyboard 'garage', the 'pencil holder' on the keyboard and signatures of the designers molded into the inside of the plastic case lid), the 1000 was also the only Amiga to play a short tune (in stereo!) when powered up, prior to requesting the Kickstart floppy. A single Zorro 1 card slot was available on the right-hand side of the machine, aligned 'backwards' from the Zorro 1 slot on the later Amiga 500. Because of the limited size of the WCS, end-user Amiga 1000 owners were limited to use of Kickstarts 1.0 through 1.3 inclusive (although several 3rd party hardware ROM solutions and freeware software soft-kick solutions quickly appeared to overcome this limitation). Once written, the WCS was write-protected and the contents were not lost until power-down (without special utilities to clear the WCS at run-time). Unlike any other Amiga (with moderate similarities to the original Amiga 3000), this machine (unless modified with aftermarket enhancements) required that Kickstart be loaded from floppy disk into a 256KB RAM space called the WCS (or Write-Control-Store) area. Following is a list of the machines this site is concerned with:Ī1000: The original Amiga. However, in many cases (particularly in earlier releases), ROM code was interchangable between 'like' machines, such as the Amiga 5 (and in some cases the 1000).

This column indicates the first machine intended to use each Kickstart ROM.
