You can use my program Digitise with any Windows (or DOS) computer that has an RS-232 serial (COM) port, and any digitiser that connects to this serial port at 9600 baud (or less). If you have different hardware, then just digitise with the software you prefer, and then convert the results to my .dig file format with a small utility program afterward. Remember, you are digitising with the Cartesian (x,y) coordinates, not with latitude and longitude. I suggest creating 3 separate .dig files: one for the fault traces; one for the coastlines and/or political boundaries; and one for a representative set of parallels and meridians. I also suggest that you use "_xy" in the name of each file, to distinguish it from the (longitude, latitude) .dig files that will be created in the next step.
