If it's a Mac Classic (model 1), then press and hold down Apple key, Option key, letter X and letter O. This will boot up System Software version 6.0.3 contained within the Mac's ROM chips. Don't hold it down forever, otherwise it will ask if you want to rebuild the desktop. This is because Apple key and Option keys held down in normal disk boot-up operation will invoke that procedure. If you end up with that response, simply select cancel.
Btw, this is the ONLY Macintosh model that has System software stored in the ROM chips.
