Starship Modifications in TNE

Hi All,
          I'm new to the list, so perhaps I missed this if it's been discussed
already.  I have been poring over the T:TNE rulebook and can't find any formula
e for calculating fuel usage by starships, either interplanetary or inter-
stellar. Is this going to be covered in a future rules manual?

Also, can anyone tell me how to successfully unarchive the FTP files at the
ftp.engrg.uwo.ca archive site?  I tried the VMS/CMS port of Uncompress but
the files still come out as garbage. Help! :0
