Afera

Afera stands for “Abersoft Forth Extensions, Resources and Addons”. It's a library for Abersoft Forth, a fig-Forth system for ZX Spectrum from 1983. I started writing it in 2015, in order to make the development of Tron 0xF easier.

Some of the main features of Afera are the following:

• Many common words and tools found in modern Forth systems.
• Improved tape support.
• 1 KiB of additional free memory on Spectrum 48K.
• 11 KiB of additional free memory on Spectrum 128K.
• Two 16-KiB RAM-disks on Spectrum 128K.
• Improved blocks handling.
• Full screen mode.
• Faster color commands.
• G+DOS support.
• Fixes some bugs of the original system.

You can browse the source code or download the zip archive below with all the files of the project. There's also a development history in Spanish.
