I mostly use an Apple and thought other people in a similar position (or Linux users) might be interested to be able to use theirs with Workpad. Apologies to those who've already discovered this. Look in the root directory of the CD (eg click on the CD in finder) and go into the 'M263' and then 'WorkPad' directories. Run the file "M263.jar" (you need Java properly set up but I think that's fairly standard with OS X and a lot of Linux distributions). Workpad should appear. The example files are in M263/Workpad/Examples as normal.
