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.
       =20
        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 (=B15 V/=B112 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?
