To my knowledge there is no HP-20S AFH. The printed and PDF manual I have is edition 5 from 1992. I also have a low quality B&W scan of edition 6. I haven't seen any differences.

The 20S is pretty much ignored here and elsewhere. You won't find out much about it. It is algebraic and a lowly "student" model so...

Not rare but not really common either. Not "collectible".

Small and light enough to fit in a shirt pocket but the classic portrait shape and not landscape like the Voyagers.

Mine is an early US made version. From my research later ones were made in other countries and can have a lower build quality. Mine is nice. Comparable to my Voyagers. Not a "plastic fantastic".
