This is a demo tape that came with Philips MSX computers. It consists of the following basic programs by W. Vliegenthart:
- Lanceer
- Adresboek
- Nederland/Aardrijkskunde

Note that there is also a different version of De Demo, with different programs. The manual/inlay describes a DEMO and an OEFEN (practice) program.
