The Apple Multiple Scan 17 Display volume of Apple's Service Source is a 101-page service manual. The PDF was distilled on 21 December 1995.
Specifications as printed
| Item | Value |
|---|---|
| Picture tube | 17 in diagonal Trinitron, 16.1 in viewable; bonded glass panel with antiglare/antistatic multilayer coating; 0.26 mm stripe pitch |
| Screen resolution | 640 x 480, 800 x 600, 832 x 624, 1024 x 768 |
| Scan rates | vertical refresh 50-150 Hz; horizontal 29-82 kHz; Macintosh, XGA, VGA, SVGA and VESA compatible |
| Video input | RGB analogue RS-343A, 0.714 V p-p positive-going; sync on green 0.286 V ±10%; separate or composite sync 1-5 V p-p, either polarity |
| Mains | universal, 90-132 and 198-260 VAC self-configuring, 47-63 Hz |
| Power | 150 W maximum |
| Size / weight | 16.5 in (424 mm) H x 15.8 in (405 mm) W x 17.6 in (452.3 mm) D; 50.0 lb (22.5 kg) |
| I/O ports | two ADB ports plus one ADB pass-through; microphone input and pass-through; headphone/speaker input and pass-through |
Being a Trinitron, this tube has damper wires: one or two faint horizontal lines across the screen are a property of the aperture grille, not a fault.
The EEPROM, and why it matters before you swap a board
The Basics chapter opens with EEPROM Settings, and the Troubleshooting chapter carries a Display Setting Restoration procedure in three parts: connect the hardware, save the EEPROM information, and restore it. This display stores its geometry and convergence alignment in non-volatile memory on the microprocessor board. Save the EEPROM contents before replacing a board, or the replacement will need a full factory realignment that the field procedure does not cover.
