3.5 inch floppy Amiga Kickstart T-shirt

The Kickstart is the most important part of the AmigaOS operating system in the ROM. Kickstart includes the exec.library (the kernel), dos.library (the DOS), graphics.library and intuition.library (the system libraries for the Amiga GUI). The versions 1.0 and 1.1 from 1985 were shipped only with the Amiga 1000, originally in the form of a bootstrap floppy loaded into a special RAM area (WOM), which was protected from overwriting after loading and could therefore only be read until the next cold start. Version 1.2 of the Amiga 500 and the Amiga 2000, the successor models of the Amiga 1000, was introduced in 1986
