The really interesting thing about Forth is just how minimalistic a bare-metal Forth implementation can be - not even an interpreter, but literally a few words handcoded in machine code, and the rest built from there (and then possibly optimized with more machine code, if you need that).
Given the ease with which Forth can be ported to other platforms and architectures, I often wonder why there's no C-to-Forth translator - it seems like it would be just about the easiest way to bootstrap things.
Bare metal like on the Ace.:)
Interesting. But in iphone we do not have arrow keys sadly. Possibly can hack ... but not forth.
I try to find a better way to try this and after reading hackaday on Forth 2017 which highlight the latest (2017) update on Forth development:
https://hackaday.com/tag/forth/ (mainly this: https://hackaday.com/2017/08/04/take-the-blue-pill-and-go-fo... )
I find this and you can run the whole thing on my MacBook in 5 minutes. It is great:
