[34S] Proposal for Entry RPN mode with dynamic stack

The more important question is do you want these saved and restored using the STOM/RCLM commands? We're limited to 64 bits here since that is how long our registers are. Adding new status bits is possible but something will have to go.

Personally, FAST is one I'd want to keep.

The LCD contrast, on the other hand, isn't something likely to be altered by a program and need restoring. In fact I don't think programs can change this currently.

So that means moving these four bits elsewhere -- what do we lose by doing so?


I suspect this is all moot unless someone volunteers to code the proposal
