None, its a plugin card on the left edge. PCMCIA I think its called.  But 
when I went looking for a different card I found them scarce, and very 
expen$ive, 3 to 4x what the usb dongle from netgear was, and those I was 
able to find that would plug directly back in, nearly all had a similar 
broadcom radio on them.

That drop of water under the bridge has been recycled a few times since.

Last time I tried to use it, nominally 10 feet from a router with a live 
radio in it, one of the neighbors smart phones kept grabbing the routers 
radio despite my having dhcpd in the router set to only accept the mac 
of the dongle.  And I got a bill from my ISP showing I had used 80GB 
more than normal that month.  So I turned the radio off, found it had 
been re-enabled a week later. That router got replaced with a gigabit 
hub. And a 20 foot piece of cat5 replaced the radio dongle. The radio in 
the r-pi running the big lathe has been shut down for the same reason.

Broadcom, spit...
