The quick summary of major differences:

- The 32SII supports equations -- editing, evaluating, solving, and integrating.
- The 32SII supports mathematics with fractions.
- The 32S was made between 1988-1991, in the USA and Singapore. The 32SII was made in the USA, Singapore, and Indonesia from 1991-2002.
