I bought a 21S last night and seached the web and this site and found very little info. A couple of manuals were on ebay that seem to sell for more than the calc. Why is isn't there more coverage? Just because it's algebraic?

I managed to get it to power up using the info in my 32sii manual and ran the tests using the same keys.

I bought it for the case and battery door but it is too nice to cannablize.

The 21S isn't even included in the museum CD.
