[Sleeping project:] A Forth for ZX Spectrum +3e.
Sleeping project. Started on 2014-11-03. 20% completed.
The project started on 2014-11, forking the code of the excellent CP/M DX-Forth 4.00. CP/M DX-Forth (there's other version for DOS) is the best Forth I know for the Z80 processor; it's a modern Forth under active development.
My goal is to write a modern and powerful Forth for ZX Spectrum, suitable for the development of any kind of programs.
At the moment there is only a detailed development history in Spanish, with code pieces and screenshots, both commented in English.
So far (2015-08) the main difficulties are:
- DX-Forth has a huge kernel.
- The DX-Forth code is not written for Z80 but for all older compatible processors, like 8080. That means the code is not so efficient as it could be.
- The development of DX-Forth is very active. That makes it difficult to follow the changes, also because the source code format and labels used by DZX-Forth are very different.
That's why I redirected the development effort to Solo Forth. DZX-Forth is not abandoned yet, though.
