[Premium-Rx] WJ-9490 DSP

[Dave]

Hi Folks,

Picked up one of this interesting little boxes recently.  It's got a 56K DSP 
along with a 16 bit A/D connected to the video input and a dual audio D/A 
connected to an 1/8" headphone output.  Anyone have any documentation on 
these?  Looks like  you talk to them via an RS-232 DB9 connector and I'm 
betting you also load the firmware that way.  This might me a nice general 
purpose demod as I've got 56K dev capabilty here.
