I was just telling the young guy here in PrePress about one of those.... LOL
Do you remember the "Mondrian" that never made it to the mainstream.
Unfortunately, I don't know of any "Barco" technicians off hand but do know a wide variety of servicemen that have worked on the likes of Scitex, Creo, Screen, etc. What location are you in as I'm in Canada but could ask these gents if they have experience for you.
Cheers!
