Verify against Apple's Macintosh Performa 400 Series Service Source (hosted): corrected case dimensions to Apple's 3.0 x 12.2 x 15.0 in; recorded that Apple documents this machine (the LC III+ under a consumer name) in the Performa 400 Series volume with 1 MB of ROM, 512K VRAM upgradable to 768K and a 114-pin PDS; added Apple's electrical, sound, microphone and battery figures and the fact that the volume has no Adjustments chapter |

'''This machine is the Macintosh LC III+ under a consumer name''', and Apple documents it here rather than in the LC Series volume: 68030 at 33 MHz, 32-bit internal data bus, burst-mode RAM access, coprocessor socket, 4 MB standard expandable to 36 MB in 80 ns or faster SIMMs, 1 MB of ROM, 512K VRAM upgradable to 768K, and a 114-pin processor-direct slot for 020/030 cards.<ref name="ssp400" /> | |||
From the '''Macintosh Performa 400 Series Service Source''', which covers the 400, 405, 410, 430, 450, 460, 466, 467, 475 and 476 together:<ref name="ssp400">Apple Computer, ''Macintosh Performa 400 Series Service Source'' ([[Macintosh Performa 400 Series Service Source]], [[:File:Performa_400_series.pdf]]), Specifications chapter and Additional Procedures, Battery Replacement (below 3.0 volts, replace the battery). This volume has no Adjustments chapter, so Apple publishes no rail tolerance and no power-supply adjustment for these machines.</ref> | |||
* '''Line voltage''' 100–240 VAC, automatically configured; '''frequency''' 50–60 Hz | |||
* '''Maximum power''' — Apple prints only three figures for the whole family: '''Performa 400: 50 W'''; '''Performa 450: 30 W'''; '''Performa 475/476: 26 W''', none including the monitor | |||
* '''Dimensions''' 3.0 in (7.7 cm) H × 12.2 in (31.0 cm) W × 15.0 in (38.2 cm) D; '''weight''' 8.8 lb (4.0 kg) — one case for the whole family | |||
* '''Sound''' monaural 8-bit input at 11 or 22 kHz; monophonic 8-bit generator feeding the same signal to both channels of stereo equipment. The '''Performa 475 and 476 alone''' have a mono input and a '''stereo output''' | |||
* '''Microphone''' electret, omnidirectional, running on '''8 V DC supplied by the microphone port''' | |||
* '''PRAM battery''' 3.6 V ½AA lithium; Apple: '''replace below 3.0 V'''. Neutralise lithium leakage with bicarbonate of soda, not vinegar | |||
'''Apple publishes no rail tolerance and no power-supply adjustment for any of these machines''' — the volume has no Adjustments chapter. The "+5 V 4.85–5.15 V / +12 V 11.90–12.75 V" pair that circulates on this wiki is Apple's Macintosh Plus and 128K/512K procedure, measured at the external drive port with voltage test cable 077-0135. | |||
