newRPL is different from RPL most noticeably in its speed (runs natively on the target hardware), use of 16 level greyscale, and two separate levels of soft menus that are customizable by the user. | newRPL is different from RPL most noticeably in its speed (runs natively on the target hardware), use of 16 level greyscale, and two separate levels of soft menus that are customizable by the user. | ||

So, for example, you won't find a **CAS** (Computer Algebra System) in newRPL, nor an equation writer. | + | If you are coming from the latest stock 50g ROM, it should be noted that newRPL is not designed to re-duplicate all the features of that ROM, but rather just the RPL part.
