Apple IIc Technical Reference Manual (Apple Computer, Inc., 1985; Addison-Wesley). Apple's own hardware reference for the Apple IIc.

The source this wiki cites for the IIc's published hardware figures, including:

• Table 11-2, external power supply - line voltage 105 to 129 V AC, 60 Hz; maximum input power consumption 25 W; supply voltage +15 V DC nominal at 1.2 A nominal; connected to the machine by a 7-pin DIN connector.
• Table 11-4, internal converter - input +9 to 20 V DC; maximum power 25 W; supply voltages +5 V +-5%, +12 V +-10%, -12 V +-10%; maximum currents +5 V 1.0 A, +12 V 0.6 A continuous / 0.9 A intermittent / 1.5 A surge under 100 ms, -12 V 100 mA, (-5 V 50 mA); maximum case temperature 60 degrees C. -5 V is derived from -12 V on the main logic board, not produced by the converter.
• Table 11-1, environmental - operating temperature 10 to 40 degrees C, relative humidity 20% to 95%.
• Table 5-2, video - low-resolution 40 x 48 in 16 colours; high-resolution 280 x 192 black-and-white or 140 x 192 in 6 restricted colours; double high-resolution 560 x 192 black-and-white or 140 x 192 in 16 colours with no restrictions. Video is available at both the RCA phono jack and the 15-pin D-type connector.
• The note that a IIc with 32K of ROM uses soft switch $C028 to bank the extra 16K in and out - the original IIc has 16K.
