How do I read old star office 5.x spreadcheet documents today? (*.sdc)

"I found a nice package in Ubuntu 10.04 that is called ""openofficedotorg-filter-binfilter"".

The description tells us that I can handle the old StarOffice format.

This package contains the ""binfilters"", legacy filters for
- the old StarOffice 5.2 formats

And after I installed it I could actually read the old file in OpenOffice."

"If you choose to install the so-called outdated filters you can mostly read the files... but if there is some formula in which a text-field is included (which was allowed in 5.x), you will get errors in all the further results.

For example if you have typed a dash in a column ('-') noting that you don't have a value (like 0 or 99), you have this errors in OpenOffice. If you can open it in StarOffice, you will not have the errors (since they are no errors) until you save it and re-open the file.
Also, included linked files will get errors after re-opening them.

Actually you can open the files in LibreOffice with the same limitations."
