Does the computer exist or a backup? In an autoexec.bat or config.sys  
file you could find a Cope Page setting ...

If not, then experimenting could help. Mac OS X comes with an utility  
to convert from one encoding to another one. It's called "iconv" –  
obviously not up-to-date since all lower-case! In Terminal you could  
type:

	iconv -l | egrep 'CP[0-9][0-9][0-9][^0-9]' | sort

It will name all those Code Pages with a three digit number, for  
example:

	437 CP437 IBM437 CSPC8CODEPAGE437
	850 CP850 IBM850 CSPC850MULTILINGUAL

All names on one line are synonyms, so it's OK to use any one name  
from such a line. In a second Terminal you then could invoke:

	iconv -t UTF8 -f 437 «your file» > «output file»

The symbols «your file» and «output file» mean: substitute the  
whole quote with a real file name.

You would need to invoke this line as long as the output is not  
correct by changing the value of the -f(rom) encoding and as long as  
there still choices left. You can create another set of modern Code  
Pages by invoking:

	iconv -l | egrep 'CP[0-9][0-9][0-9][0-9]' | sort
