You'll need to split up the board into sections (haven't played that game in years myself either, so probably would need to scan it 6-8 times in order to get the full board) at a very high resolution. When I need to stitch together a large photo/poster I'll scan it at 600dpi; what gets difficult is lining up the scans into one large picture where all the edges line up properly and the map is geographically correct. Depending on the version of PS there's a built in function for printing poster by using multiple sheets of paper. Put in the paper size and it'll calculate what sizes it needs to make and once its printed you just line them up.

If you have a small scanner and/or no color printer then its academic. Only solution is probably going to be Kinko's or a local print shop if you can find one. A (real) print shop would be ideal, if you have a local one that's privately owned and been around the neighborhood for many years you'll probably have the best luck there out of all the options. Places like Kinko's have no problems with hitting you hard with the pricing, someone local is more likely to be friendly and give you a discount or charge you at a greatly reduced rate (especially if he/she also was and Axis & Allies player from way back when as well).
