# 65X-DOS

This source tree builds a 512KB .bin file used to burn the system ROM
for Sentinel 65X. It is designed to be modular; the kernel and boot code
use only the lowest 64KB of the 512KB ROM, leaving plenty of room for
additional software in ROM. In future, more modules are planned:

 - A command line shell
 - A 65816 macro assembler
 - A text editor
 - Your idea here!

 To build the kernel and ROM image, you will need the Calypsi toolchain (https://calypsi.cc),
 as well as GNU make. To build the fonts in the ROM image from the image file,
 you will need Aseprite (https://www.aseprite.org).
