I would like to if anyone out there has upgraded their GIS system from PC ArcInfo 4.0 to ArcInfo 9.X? We are presently in the process of implementing a budget and we could use any information that would be of use to us. We are upgrading our desktop computer and are in the process of purchasing ArcInfo 9.2 from Esri Canada. We have a Calcomp 111 digitizing board and a HP design jet 450 C printer. I am not sure if these are compatible with ArcInfo 9.2. I look forward any suggestions.
