Sadly, the Duke website does not have the files for an early SS (Pre-95 I think). Thank goodness for the Bluepoint website - its class, but you really do need broadband for the downloads
Likewise the CD's I've seen on Ebay are to be avoided as I'm told they are all downloads from the Ducati website with some extra piccies thrown in.
Failing that I'm sure on of the SL lads can advise / take a piccy for you.
good luck - Frank
