WP 34S --> WP 31S

[Paul Dale]

The software all comes down to how far you want to optimise and change things. There is a lot that can be taken out of the 34S to produce the 31S. Most of this is fairly pointless but it would make for a cleaner internal design -- why get rid of complex mode without the complex prefix being present e.g.? It would save flash space but without being programmable, there isn't much point in that even.

I doubt I've got time to recode things to make it work at present or anytime in the near future. The more changes that are made, the more software rework is required.

Of course a full 128kb of flash dedicated to a non-programmable scientific calculator might be fun to try eventually.
