Good evening, oops good night from Belgium to you.

I think you might find what you need on Zanchetta's Site: Just go from here to "Links" (bellow, on the left), then "Links rund um das Thema Schachcomputer", scroll down to Zanchetta's Sitebutton, enter that. On this site you'll find a button manuals/documentation. Go for Mephisto. There you can download an PDF of a Vancouver 68020 in Englisch (second from the bottom). That should do nicely for the Lyon 68020 and Genius 68030 as well, as they are after all very similar (awfully close to identical, let's say).

Nice buys!. You... payed in pounds?

Greetings
Xavier
