As a hobby I've still continued small research projects. Few of them were done in field of embedded computers.
In 2007 I've purchased one of the first ARM based MOXA computer.
With program written in GNU C and using uC-Linux operating system this small device was able to record my car route and store it in simple text format for further processing. At the time this MOXA PC had no build in graphic card. The only option you could use to interface them was the www interface over ethernet or terminal connection.
