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).
