I have got one of these cards.  It has a coaxial-type (like a tv aerial) connector.  is it possible to get this to work on a broadband modem with miami dx and/or genesis and an a4000.  Do broadband modems use the same coaxial connector or do i need and adaptor? if so what sort.  I have very little knowledge of broadband and amigas connected to it

I am bringing this old post back up because i found its easy to convert these to rj45 twisted pair,no thanks to a 20+ year typo on amiga resource and big book of amiga.

Those sites say one of the parts to convert to rj45 is a pt4059 by pulse/vicor.
Looking at the pictures i wasn't so sure of the part number. This IS a typo.. the MB86961 datasheet for the ethernet chip this card uses specifies PT4069.

Datasheet here: see footnotes: http://www.datasheetspdf.com/pdf/534012/Fujitsu/MB86961/7

The PT4069 is still readily available,adding 6 resistors,2 caps and a rj45 jack makes twisted pair work on this board!  

I just bought a PT4069 here:

UPDATE: pt4069 also crosses to HALO TD42-2006Q

UPDATE2: for qn2000 v1.1 cards..If you want to use the AUi PORT WITH A AUI->TWISTED PAIR ADAPTER,IT IS POSSIBLE:
the aui port is missing some ground connections as anthony hoffman mentioned. only pins 1&4 are grounded,you need to jumper from pin 4 to pins

6,8,11,and 14...like this:

Figure 3-23: Ethernet AUI Connector Schematic Diagram  

 

Make sure the fuse is in place on the quicknet board. 500ma will do.
This will get the transceiver working. 3 of 4 lights on the centrecom should be lit.
Centrecom 210ts will fit if you remove the casing,hidden screw on the bottom middle under the label.unscrew and remove the aui port standoffs for it to fit.
Use the MiamiDX mni driver called z2-mb86950.mni,not the sana 2 driver.
in 3000/4000Towers(and A2000) quicknet switch must be down. in desktop models it would be pointing away from the PSU.
Use the miamidx
z2-mb86950.mni driver.
