Interesting prototyping approach
I thought this Crowd Supply project, the ELLO 2M, might spark a few ideas for those who have been constructing their own calculator prototypes. The approach taken by this builder is to construct a simple computer using a stack of six PCB's. The processor, memory, keyboard, keys and display are all contained within or constructed from one of the PCB layers. Here's a link to the project

Looking at the second posted video, the keyboard certainly doesn't look "HP quality" but it would be adequate, and obviously easily changed. Certainly a fairly clever twist on the task of producing a prototype.
