There is not much special about this computer, except that this type was used in the advertising with Katja Schuurmans to promote the Laser Computers brand and also this computer.

There is also a tower variant, the Laser Expression 514P, with the same hardware and also a sticker of Katja on the front.

By default, this computer was supplied with a CD containing the games and software which are shown in an explanatory film by Katja. In addition, there was also a Laser mouse pad and an audio CD with the hit 'Maar nu heb ik er één' (But now I have one), known from the advertisement for this computer.

Thanks to this marketing, Laser Computers became a very well-known brand in the Netherlands.
