Good old Computer Based Training

A few days ago I was asked to draft a cost calculation for a good old Computer Based Training program that should be produced for CD-ROM.
The CD-ROM to be produced is meant for our team of the University of Twente that competes in the last round of the Battle of the Universities. Our team is planning on producing a complete learning package meant for 12-16 year old students in secondary education on the subject of Tissue Engineering. The whole package also will include a DVD, lesson plans for teachers, as well as instructions and stuff for practical exercises that students that can do.
Actually it was really great to draft this calculation. It has been years (at least 6 or 7) since I have been involved in producing learning materials for CD-ROM. We now all work with the internet, isn't it? I therefore asked "Why a CD-ROM?". And the answer I got back was very practical: "A lot of schools don't have a proper internet connection; they would all miss out on this.". That really set me back with both feet on the ground!
