When it came time to ship the Amiga in 1985, Commodore engineers found the OS too buggy to include on built-in ROM chips in the computer. (And that's too bad, because it would have allowed the Amiga to boot instantly just as other early PCs did.) Instead, the engineers devised a workaround called the "Writable Control Store" (WCS) that fit on a daughterboard attached to the motherboard via long multipin headers where chips would normally reside. The WCS included 256KB of memory used specifically to hold a basic OS that had to be loaded from a floppy disk at boot time.
