Reasons for reuse and upcycling

There are multiple reasons why our embedded experts recommend upcycling.
Hardware/operating systems are often considered outdated, even though they are still doing their job. In most cases, such applications have been elaborately developed over many years and in some cases have already been in use for 20 years. They have proven themselves, run stably and are now almost error-free. 
In addition, they were often developed at times when quality was the main factor and not only costs determined the development time.
