I tried to e mail Mark Friedman but it did not work so I hope the respons
will be of interest to all.
 
Mark - at the Marine Museum of the Great Lakes at Kingston we are now
seaching for a laserdisk system. I am interested in  the equipment
your are using at the Mariners and if you are giving viewers a
choice of programme material from the same disk - if so what
kind of control devices are in use.
 
Thank you.
Maurice Smith, Curator.
