No, the servers are proper Server GIS technology, although old at this stage. So the rendering for the web application for the ordering was all via ArcIMS. The actual map production, once an order was placed for either hard copy or digital, is done as batch processes on more or less Desktop software, acting in a bank. More recent technology would allow this output process to work on a true server, but it worked/works quite well.
A brewery in Celbridge rings a bell, but I never mapped one. Do you have any references to point us to?
