Size and weight detail
Size and weight detail	Published UK brochure metric measurements retained: 15.2 cm high, 33.0 cm wide and 41.9 cm deep; 11.3 kg varies with installed internal devices	Apple catalogue: 455 × 343 × 419 mm (height × width × depth), 18.3 kg, varying with installed devices. Service Source rounds the same 17.9 × 13.5 × 16.5 inch case to 455 × 344 × 420 mm and 18.4 kg; headline follows the catalogue’s published metric values
Power supply
Power supply	UK Apple brochure gives 100–240 V AC, 50–60 Hz single phase and 112 W maximum excluding monitor. Archived Apple support lists 230 W maximum; shared service manual lists 200 W AC and 112 W DC. Preserve these different ratings rather than treating them as measured consumption. 3.6 V lithium clock backup battery	Automatically configured 100–240 V AC mains; service supply operating range 90–264 V rms, 50–60 Hz ±3 Hz
Power use
Power use	–	Service Source: 120 W maximum for all line and load conditions. Current support article describes a PowerPC-upgraded configuration and lists 60 W, so that figure is not transferred to the original model
In the box
In the box	System 7.1 and System Enabler 001, documentation, mouse and microphone; keyboard and monitor sold separately. Apple announced the IIvi on 19 October 1992 for selected countries outside the US. UK ordering brochure is printed September 1992; neither its print date nor introduction establishes first actual retail sale, so released is omitted	Original 68LC040 model is offered in Apple’s April and October 1995 catalogues; the latter identifies US education-only sales and varying worldwide configurations. Current Apple support article describes an installed PowerPC 601 upgrade card. It records introduction on 3 April 1995, while contemporary Macworld says education shipping was planned for that day; exact actual first retail delivery is unconfirmed, so release retains supported year precision
