Inside the Linksys wma11b
Want to see inside the wma11b? It’s probably the easiest linux device to open you’ll find, much easier than a Tivo..
Just work around the edge of the case from the bottom and it will just pop apart.
Above is what you’ll first see. Very simple pxa250 motherboard with a 802.11b pcmcia card neatly mounted on the top. We’ll see how easy it is to upgrade it to a 802.54g later.. ;-p
This is the view with the pcmcia card removed. You’ll see the xscale processor under the pcmcia card mount. A davicom network 9000e fast ethernet controller on the left, The audio AC97 audio module is a sigmatel stac9750, it’s not visible in the photo but is just left of the Focus FS450 TV signal generator at the centre top. You’ll also see 2 8mb Dram modules on the right.
This picture is a close up of the blanks for a serial package. U2 is for a MAX241, J6 is a serial connection with ground, tx and rx, and JP1 is a JTAG connection.

Looks neat!
Did you ever get to add a 802.54g card to it? if so did have to be a prisim based?
Does the PXA250 feature a PCMCIA controller or the pins used for the PCMCIA card is actually GPIOs?
If the card were to be upgraded to 802.54g is there any possibility for video streaming? i.e. can the Focus FS450 handle that?
Cheers

I tried but had no luck. It’s only a 16 bit PCMCIA interface and the 54g adapter I have is 32. I’d be suprised if there were any 16 cards about that could do that anyway.
Also the video capibilities of the wma11b are not what you’d call fast….
