The April 1998 datasheet and archived support sheet give the later figures; the later revision-specific technical note is followed here. PowerPC Mac with Mac OS 7.5 or later, or Windows 95/NT; see manual exclusions for older Macs and graphics cards.	Apple support dates introduction to 5 January 1999 and the revision-specific technical note identifies the 1999 San Francisco Macworld launch.
