Yep.

A seven segment display component would be a nice introduction to
using the SID API.  Please consider porting your component.  There is
plenty of programmer documentation on the web pages.

These would be great to have in SID, if you're feeling like it!

In general, this is the philosophy of SID components: only simulate
sufficiently for target software to execute correctly.
