Description
R47/C47 was originally forked from the WP43 project under the name WP43C, then changed to C43 and eventually in 2023-01 to C47. Much of the underlying math capabilities are originating from WP34S, most of which identical with WP43. A major aim of the C47 project was to use the default key labels of the DM42, which will also be very familiar to users of the HP-42S. No key stickers are required, and the user interface is modified to work with a single shift key.
