Uxn11

An emulator for the Uxn stack-machine, written in ANSI C.

Uxn11/System

This emulator's system device supports changing a stack's location to a page of memory. The default memory mapping is as follows:

• 0000-ffff, as RAM.
• 10000-100ff, as working stack.
• 10100-101ff, as return stack.

To use the last page of ram(0xff00) to host the working stack:

#ff .System/wst DEO

The stack mapping is 254 bytes of data, a byte for the pointer and a byte for an error code.

Graphical

All you need is X11.
