The HP-37s scientific calculator?

[Paul Dale]

I mostly wish that the 35S could have been repurposed.

• It has the same ROM size as the 20b/30b/34S.
• It has five-eight times the RAM of the 20b/30b/34S.
• It has a nicer colour scheme and keyboard.
• It's a scientific calculator.
  

We could have performed surprising magic using the 35S as a base. Instead we were forced to use the 20b/30b and had to make some (albeit not too many) compromises.
