# Sentinel 65X ROM Firmware

This source tree builds the 512KB .bin file used to burn the system ROM for Sentinel 65X. It consists of several modules:

  • boot: initial boot code
  • irq: interrupt handler vectors and trampolines
  • bios: essential hardware driver code and IRQ handler implementations
  • bdos: core operating system

In future, more modules are planned:

  • A 65816 macro assembler
  • A text editor
  • Your idea here!
