Heinz' advice is sound, I've found major differences that aren't 
reflected in the manual backdating change sheets.  I'd suggest that you 
get your serial number and then compare with the copies at 
http://www.hparchive.com/hp_equipment.htm    But check the backdating 
details in Appendix C rather than relying on the cover sheet, which for 
my s/n block was never updated.
