OK. I bought one this afternoon. I can give you all the information that I can get from outside. I am not such a hacker so I am waiting but I was willing to put my ante of $20 (a bit more with CA sales tax..)
The model # is as everyone knows, Dakota digital PV2 but actually from the technology from Pure Digital Technologies, Inc located in San Francisco. I have no idea who made the first version.. but assume that it is the same..
The package says that I can take as much as 25 picture and the ad misleaded as if I can erase any picture that I took but apparently I can erase only the one that I just took. not sure if I can browse old pictures.
The bottom of the camera says it is model 410.. is it the same as the old one ? The shop that I bought PV2 claimed that they also have PV1 but I could not find one and the clerk disappeared before showing one to me.
There's a little door at the bottom of the camera that would look like a door for battery. I am afraid if this battery isn't rechargeable but even in that case we should be able to use a stock NiMH.. The size guggests that this camera uses just one or two AA battery. Yes it is battery door that contains TWO AA alkaline batteries. No marking for polarity. so be a bit careful.
The signal connector is hidden with a paper tape and the tape says that:
To protect your pictures, this sticker should only be removed by a Ritz Associate. Camera CANNOT be connected to a home computer.
My gut feeling is.. the connector is compatible with PV1 because otherwise the whole infra structure has to be reconstructed. But there is a possibility that they incorporated a simple encryption scheme to the picture.. not quite likely though.
I asked the picture quality but the clerk answered that the picture quality is pretty good while he failed in showing me any example.
The connector has 10 silver pins.. (I removed the sticker but that is OK because I didn't take any picture and the sole purpose of the sticker is to protect my pictures

) if I call the bottom most pin as #1, pin 2, 7 and 10 are longer than the others. I would assume that they are GND or VDD wires. There are 7 signal wires left.
That is about it..
