I recently got hold of the latest prototype of the above data logger

has 4 MB RAM.

I suppose this signifies that everything in the device is free software.
The device is not in production yet, but I am reviewing it because I
feel that efforts like this need to be encouraged - very good job of
adapting a device for the use of the enthusisastic mapper.
