I picked up a couple of Netgear PTV1000's on the cheap recently for those not familiar the device uses intel WiDi to extend your laptop display and audio over WiFi and the out to HDMI or composite.

http://www.netgear.com/home/products/ho … V1000.aspx

I decided to crack one open and take a look and identified the following:

2x samsung 512mb ddr2 dram k4t51163qg-hce6
1x Sigma Designs smp8653a-cbe3 processor (Non marcovision version of the smp8652) http://www.sigmadesigns.com/uploads/doc … 650_br.pdf
1x pegatron Et856 94V-0 Ralink RT3070 802.11b/g/n Wireless Lan Device connected via internal female usb port
1x 24-bit stereo DAC akm 4421aet 3e937 http://www.asahi-kasei.co.jp/akm/en/pro … 4421a.html
1x st nand512w3a2dn6 NAND flash covered in sticker "WiDi 1.056.2 f2 9683f516"
1x sil9002csu hdmi transmitter

1x 2x10 20 pin test pad near CPU marked J18 (JTAG?)
1x 1x4 male header marked con28 (Serial?)
1x 2x7 14 pin test pad marked j15

firmware source: ftp://downloads.netgear.com/files/GPL/P … ar.bz2.zip
firmware readme http://www.pastie.org/1508140

So for $55 USD this device seems to have good potential as a media streamer or otherwise and I plan on getting to work once I have some time.  If anyone has any experience with the processor or device I would be glad to hear form you.

Cheers.

I have one as well.   I downloaded the source, but it didn't build cleanly first try and haven't had time to figure it out.

the 1x4 header is TTL (3.3V) serial.
