Got a old first model CED.
Still works fine, just has the serial port and the old software is only for old versions of windows.
I fixed up a very old work laptop with Linux and use a serial port console set up on it. Then dump the data (shot strings) when I get home or plug the laptop in the truck and grab them right there.
Don't use it much anymore, I used it a lot when I was competing in LR matches.
Don't shoot whatever you get!
Good luck
