	Apple prints a ~~'''~~90-132 VAC~~'''~~ supply for this display and ~~no 220~~-~~240 V figure, so this volume documents the domestic unit only~~.		Apple prints only a 90-132 VAC supply for this display. The Specifications chapter also gives full monitor timings (porches, sync widths, dot clock, line and frame periods) for 640 × 480 at 60 and 66.67 Hz, 800 × 600 at 60 and 72 Hz, and 832 × 624 at 75 Hz (pp. 3-5).<ref name="spec" />

	The ~~Specifications~~ chapter ~~also prints~~ '''~~full monitor timings~~''~~' (back porch~~, ~~sync width~~, ~~front porch~~, ~~dot clock and line/frame periods) for 640 x 480 at 60 and 66~~.~~67 Hz and for 800 x 600 at 60 and 72 Hz~~. ~~Those tables are the citable source for this display's timing, and they are reproduced nowhere else on this wiki~~.		The Basics chapter documents a known issue: on some displays the picture shifts right at 832 × 624 and cannot be centred, and model M3935LL/A does not support 832 × 624 at all. In November 1995 Apple started an upgrade programme to a Revision B display; the chapter has Apple's table of which computers qualify and a Monitors control panel test for the rest.<ref name="basics">''Apple Multiple Scan 14 Display'' Service Source, Basics, "Repair Issues: 832x624 Resolution", pp. 3-8 (PDF pp. 5-10).</ref>

There is no Take Apart chapter and no exploded view: the symptom charts end at "Return monitor to Apple".
