RP12C now lives on its own full-width calculator page.

The emulator has moved off the homepage so it can stretch into a more faithful HP12C-style silhouette: a broad display deck, dark keyboard body, and a key layout that feels more like the Voyager calculator itself.

What changed

The calculator now opens on its own route at `/calculator`.
The new `/practice` route adds accuracy-first RPN drills with the real calculator face.
The home page now acts as the hub for calculation and practice.

Example

Basic RPN arithmetic

12 ENTER 3 x

Push 12, duplicate it into the stack, then multiply by 3 for an immediate 36.

Example

Fast percentage work

200 ENTER 15 %

Treat the second value as a percent of the first and keep your workflow in stack form.

Example

Voyager-style calculator page

/calculator

The emulator now lives on its own route so the device can sit wide and read like an instrument rather than a home-page card.

Example

Minimal practice page

/practice

A quiet, Monkeytype-like route for drilling canonical RPN sequences with the real calculator face and live keyboard input.
