The Commodore A1060 Sidecar is an expansion hardware device developed by Commodore and released in 1986 for the Amiga 1000 computer. It features a complete PC XT-clone system mounted in an expansion case which connected to the expansion bus on the right side of the Amiga 1000 computer, sitting beside it similar to a motorcycle's sidecar, hence the name.
The PC side of the Sidecar was built around an Intel 8088 processor. All I/O procedures from the PC side are performed by the Amiga. Software was included to allow data to be exchanged easily between the PC and the Amiga side of the system. The Sidecar was available with an internal hard disk which was accessible from both the MS-DOS and AmigaOS environments. This was the first hard drive produced by Commodore for the Amiga.
