                     10: You can get to the ROM monitor or break into the debugger (once the

1.1       mspo      105: 
                    106: For monochrome systems (NeXT Computer, NeXTcube, NeXTstation, NeXTcube
                    107: Turbo, and NeXTstation Turbo) without a NeXTdimension board, a 19 pin
                    108: cable connects the system to the mono MegaPixel Display. The cable
                    109: carries power for the monitor, video for the monitor, sound in and out,
                    110: and the keyboard/mouse connector. The keyboard plugs into the monitor,
                    111: and the mouse plugs into the keyboard.
                    112: 
                    113: For color systems (NeXTstation Color and NeXTstation Color Turbo) a
                    114: funky "Y-Cable" connects the system to a soundbox and to a monitor. The
                    115: monitor end of the cable is a 13W3 connector. You can use any multisync
                    116: monitor (with the appropriate adapter) or a fixed frequency monitor
                    117: supporting the appropriate refresh rate. NeXTstation Color supports 68
                    118: Hz refresh at 1280x1024. NeXTstation Color Turbo supports 72 Hz refresh.
                    119: The soundbox provides the additional functionality of the mono MegaPixel
                    120: Display (sound in and out and keyboard/mouse connector). The keyboard
                    121: plugs into the soundbox, and the mouse plugs into the keyboard.
                    122: 
                    123: For cube systems with a NeXTdimension board, the refresh rate is 68 Hz.
                    124: If the cube is using a mono MegaPixel Display in addition to the
                    125: NeXTdimension driven display, a simple 13W3 cable is used to connect the
                    126: monitor to the NeXTdimension. If the cube is not using a mono MegaPixel
                    127: Display, you must use a "Y-cable" and a soundbox connected to the
                    128: NeXTdimension board.

1.2     ! wiki      130: #### Differentiating ADB and non-ADB keyboards and mice
1.1       mspo      131: 
                    132: Currently, only non-ADB keyboards and mice are supported.
                    133: 
                    134: Non-ADB keyboards use a mini-DIN connector with 5 pins. Non-ADB
                    135: keyboards have a black power key between the brightness and volume keys.
                    136: Non-ADB mice use a mini-DIN 8 connector. Non-ADB mice are rectangular.
                    137: All NeXT hardware supports these peripherals with the original mono
                    138: MegaPixel Display (N4000 or N4000A) or a non-ADB soundbox (serial number
                    139: prefix ABN). The ADB monitor and soundbox cables will work with non-ADB
                    140: monitors and soundboxes. Non-ADB monitor cables (part numbers 150 or
                    141: 1532) and soundbox cables (part number 2286) only work with non-ADB
                    142: monitors and soundboxes.
                    143: 
                    144: ADB cables have mini-DIN 4 connectors. ADB NeXT keyboards have a flat
                    145: green power button. ADB NeXT mice are rounded. Apple Macintosh ADB
                    146: keyboards and mice should also work. ADB peripherals are only supported
                    147: on NeXT hardware with ROM version v.74 (most turbo systems and some
                    148: later non-turbo systems). You also need a newer mono MegaPixel Display
                    149: (N4000B) or ADB soundbox (serial number prefix ADD). Additionally, you
                    150: need an ADB monitor cable (part numbers 4534 or 4535) or an ADB soundbox
                    151: cable (part number 4536).

                    162: FAQ](http://www.peanuts.org/faq-serve/cache/189.html). Also, see this
                    163: [post](http://mail-index.NetBSD.org/port-next68k/1998/06/30/0000.html)
                    164: describing how to build a better switch.
                    165: 
                    166: The procedure is to just touch pins 6 and GND on the DB-19 NeXT monitor
                    167: out with a 470 Ohm resistor (450 is the actual resistance, but 470 ohms
                    168: is more commonly found in resistors). The touching with the resistor
                    169: will be momentary, you shouldn't try to set up a resistor so that it's
                    170: always touching.
                    171: 
                    172: Pin 6 is the power sense, and pins 13-19 (and the DB shell) are the GND.
                    173: Just say "pin 19", it may be easier. There's a pinout diagram of the
                    174: DB-19 in the NeXT Users Reference Manual, as well as
                    175: [below](#monitor-pinout).
                    176: 
                    177: If you have an old Cube (serial number below AAK0016370), the power
                    178: supply needs to have more power drawn from it than an 030 (and 040?)
                    179: board uses to stay on. So: On the DB-19, attach a Power Resistor (20
                    180: Ohm, at least 20 Watt) between pins 12 and GND. (Pin 12 is -12V, pin 13
                    181: works well for GND). Then just "momentarily touch" the 470 ohm resistor
                    182: as described above, and you're set. The 20 Ohm resistor draws enough to
                    183: keep the power supply happy - just don't touch it (\*HOT!\* ;-)
                    184: 
                    185: To power off, type "halt -p" as root on the machine (either through a
                    186: terminal connected to port A, or over the ethernet connection).
                    187: 
                    188: Also, you need to use the NeXT keyboard to set up the [ROM
                    189: Monitor](#rom-monitor). The important ones are:
                    190: 
                    191: -   Wait until keypress? N
                    192: -   Sound out tests? N
                    193: -   Port A as alternate Console? Y (if you have one, it's nice)
                    194: -   Verbose mode? N (this may need to be N to work)
