Virgil Dupras 650481f849 z80/8086: extract 2>R code from stable ABI zone
Only its jump at 0x33 remains.

I've also fixed a strange offset oddity in 8086's (n) placement.
It was off by 2, but strangely, it ran properly. Anyway, now it's
fixed.

emul

This folder contains a couple of tools running under the libz80 emulator.

Requirements

You need ncurses to build the forth executable. In debian-based distros, it's libncurses5-dev.

Build

First, make sure that the libz80 git submodule is checked out. If not, run git submodule init && git submodule update.

After that, you can run make and it builds the forth interpreter.

Usage

The ./forth executable here works like the one in /cvm, except that it runs under an emulated z80 machine instead of running natively. Refer to /cvm/README.md for details.

Not real hardware

./forth doesn't try to emulate real hardware because the goal here is to facilitate "high level" development.

These apps run on imaginary hardware and use many cheats to simplify I/Os.

For real hardware emulation (which helps developing drivers), see the hw folder.
