I have one of these... came from a Sony branded WebTV unit I got at a garage sale. I use the keyboard with my DishNetwork satallite decoder (their Dish Player 7000 model... their original PVR model... it has a webTV unit built in along with the ability to pause and record TV... and no, I don't use the webTV features... I wanted the keyboard to make my life easier in spelling out TV shows I was searching for, so when I saw a webTV for sale for $5 I grabbed it). Since I think my decoder is made by JVC, that should tell you that at least all the webTV keyboards are cross compatible and not manufacturer or model specific. Beyond that tiny tidbit of info, I can't help much more until monday. I don't have a little screwdriver at home right now that can open it up to see if there is any better info inside. -chris <http://www.mythtech.net>
