I have just acquired an digital AXPpci 33 Alpha motherboard, which i am
dying to get working so I can get FreeBSD on it!!

Anyone know anything about these, specifically it looks to take a special
power supply, which I am having trouble Identifying.

from it's manual it states...

	The MLB has two power input connectors (J33 and J34). The main power

	connector (J33) is a 12position (1 x 12) vertical malekeyed
connector. The 
	mating connectors required by the main power source are a Molex
90331 
	style housing (or equivalent) for positions 1--6 with a key at
position 4, and 
	a Molex 90331 style housing (or equivalent) for positions 7--12 with
a key 
	at position 1. 
	
	Connector J34 supplies +3.3 V to the PCI option slots. This is a 
	12position (1 x 12) maleshrouded keyed connector. The mating 
	connectors required by the +3.3 V power source are a Molex 90331
style 
	housing (or equivalent) for positions 1--6 with a key at position 5,
and a 
	Molex 90331 style housing (or equivalent) for positions 7--12 with a
key at 
	position 6. 

and the pinning is as below:

	Table 2--1 DC Power Connector (±5 V/±12 V) PinOut (J33) 
	Pin Number 	Function 
	1	 	POWER GOOD 
	2 		+5 V 
	3 		+12 V 
	4		 12 V 
	5 		Ground 
	6 		Ground 
	7 		Ground 
	8 		Ground 
	9 		5 V 
	10 		+5 V 
	11 		+5 V 
	12 		+5 V 

	Table 2--2 lists the pins and functions of the dc power connector
(J34). 
	Table 2--2 DC Power Connector (+3.3 V) PinOut (J34) 
	Pin Number 	Function 
	1		Ground 
	2 		Ground 
	3 		Ground 
	4 		PCI +3.3 V 
	5 		PCI +3.3 V 
	6 		PCI +3.3 V 
	7 		PCI +3.3 V 
	8 		PCI +3.3 V 
	9 		PCI +3.3 V 
	10 		Ground 
	11 		Ground 
	12 		Ground 

Anyone know of a power supply like this or where I can get one, or I'm I
doing some constructing?
