There are competing issues with the first goal. It is very important that the machine's original "character" remain intact. If restoring it to operation should require significant changes, then its better to not do it.
The Computer Museum in Boston restored several machines but this is the first such project in California. We're expecting to learn a lot which will help future projects.
The 1620 web site and simulator are prototypes of what could be done for other machines in the museum's collection.
