Power and support
Power use
Power use	Service Source and November 1997 maker brochure 150 W maximum; brochure less than 30 W standby and less than 5 W suspend/CPU energy-saving. EveryMac's secondary 180 W figure is not substituted.	Maximum 180 W operating; less than 30 W standby; less than 5 W when the computer is in energy-saving mode
Power supply
Power supply	90–264 V AC, 47–63 Hz; these mains ratings are not screen refresh rates	90–264 V AC, single-phase 47–63 Hz; mains frequency is separate from display refresh
Software
Software	System 7.1 or later and 68040 or later Macintosh processors for AppleVision software; Windows 95 compatibility with supplied adaptor. Maker 5 May 1997 press release says non-AV850 available immediately worldwide while 850AV was expected in June; no AV date substituted. Service Source explicitly describes the November 1997 ColorSync Display rename as the only product change at that point; no duplicate renamed model or unsupported successor link. Brightness and contrast ratio are unpublished.	Maker announced the new Studio Display family on 5 January 1999; January retail precision is used because a distinct first-sale day is unconfirmed. January M6204LL/A datasheet requires the new Power Macintosh G3 with built-in USB and Mac OS 8.0 or later. Brightness and contrast ratio are unpublished and omitted; no pixel density is assigned to this CRT.
