On the shoulders of giants.... Smile

Well, first I need a firmware image I can give out to people that follows the new keys. I am in the process of developing it, I am basing it on another RPN language core I wrote called 'levity' for an internal project a long time ago. The main thing I am salvaging is the nice compacting GC, so I can use space inefficient but oh so easy to manage linked lists for the youngest generation that lives in the 6k of ram, then garbage collect it compiling it down to linear arrays and compressed bytecode that live in the 2K that are backed up. A further GC moving stuff to flash that has existed at least a day is even possible. But a nice thing about the generic GC core is stack items can be any size, vectors, matricies, complex numbers, it doesn't matter because they are structs in memory that are only compacted when they exist for a certain amount of time.

Heh. the front panel image is auto-generated from the source as I work on the firmware so is in flux, but coming together. The newest version is attached which is hopefully more aethetically pleasing.
