Can we use our own laptop and router to run the Difference Engine?
> Not at the moment – in due course we expect to turn it into a downloadable software package, but as things are changing so rapidly at the moment as we continue to develop it, and to ensure any problems encountered are not due to hardware, we’re only making it available on our kits for now

Can we buy our own Difference Engine system?
> The Difference Engine is only available to hire. In due course we expect to turn it into a downloadable software package (see above)

How much does it cost?
> Hire fees vary according to length of time you need it for and the size of your organisation.  Get in touch and let us know your needs and we’ll quote you a price.  The aim is to keep this very affordable, especially for small companies!
