Size and weight detail
Size and weight detail	Original brochure lists 40.6 × 19.8 × 42.8 cm (height × width × depth), matching the service manual. Weight is 20.18 kg without the monitor and varies with installed devices; the service manual explicitly excludes the CD-ROM drive. The technical booklet transposes depth and height labels.

Power supply
Power supply	Exact specification page and ordering brochure list 220 W maximum, 100–125 or 200–240 V AC at 47–63 Hz. The shared service manual agrees on 220 W maximum continuous but gives wider voltage bands; the original technical booklet instead states 140 W input and 98 W DC output. These conflicting ratings are retained rather than treated as measured consumption.	Maximum 30 W; 100–240 V AC, 47–63 Hz; 3.6 V lithium clock battery
