To boot from a SCSI disk, type bsd(). To boot from the ethernet, type ben()netbsd.
NeXT ROM Monitor 2.5 (v66)
CPU MC68040 25 MHz, memory 100 nS
Backplane slot #0
Ethernet address: 0:0:f:0:fb:90
Memory size 40 MB
NeXT>?
NeXT ROM monitor commands:
p inspect/modify configuration parameters
a [n] open address register
m print memory configuration
d [n] open data register
r [regname] open processor register
s [systemreg] open system register
e [lwb] [alist] [format] examine memory location addr
ec print recorded system error codes
ej [drive #] eject optical disk (default = 0)
eo (same as above)
ef [drive #] eject floppy disk (default = 0)
c continue execution at last pc location
b [device[(ctrl,unit,part)] [filename] [flags]] boot from device
S [fcode] open function code (address space)
R [radix] set input radix
Notes:
[lwb] select long/word/byte length (default = long).
[alist] is starting address or list of addresses to cyclically examine
Examine command, eith no arguments, uses last [alist]

Pin 6 is the power sense, and pins 13-19 (and the DB shell) are the GND. Just say "pin 19", it may be easier. There's a pinout diagram of the DB-19 in the NeXT Users Reference Manual, as well as below.
If you have an old Cube, the power supply needs to have more power drawn from it than an 030 (and 040?) board uses to stay on. So: On the DB-19, attach a Power Resistor (20 Ohm, at least 20 Watt) between pins 12 and GND. (Pin 12 is -12V, pin 13 works well for GND). Then just "momentarily touch" the 470 ohm resistor as described above, and you're set. The 20 Ohm resistor draws enough to keep the power supply happy - just don't touch it (*HOT!* ;-)
To power off, type "halt -p" as root on the machine (either through a terminal connected to port A, or over the ethernet connection).
Also, you have to have the ROM Monitor settings done correctly. The important ones are:
