March 2016 - Note about these pages :

This is a very historic website, originally created for educational purposes in 1996, when it was hosted at www.prodigy.net .
In the 20^th century dial-up internet connections were very slow and all photos had to be scanned into the smallest possible digital files.
Now these pages look even more primitive than back then - some non-functional scripts had to be replaced with plain text,
that is also rather enthusiastic than professional presentation.
So look at this web site with a smile, like finding an old school notebook from the last century.
