#!/bin/bash
# Version 5
#
# Purpose: Assemble, Link, & Copy a binary to a DOS 3.3 .DSK image without all the cc65 library crap.
# Usage: src2dsk.sh {sourcefile}
#
# Example:
# 1. src2dsk.sh barebones.s
#
# foo.s <- input assembly source file
# foo.o <- output of assembler
# foo.bin <- output of linker
# foo.dsk <- DOS 3.3 disk contaning binary 'FOO'
#
# 2. Mount 'barebones.dsk' in your emulator
#
# If you try BRUN'ing the file the RTS won't exit to DOS 3.3 / BASIC properly.
# A simple work-around is to BLOAD, then run it.
# 3. BLOAD BAREBONES
# 4. CALL -151
# 5. AA72.AA73
# 6 Use whatever addres is displayed (bytes are swapped):
# 1000G
#
# The 'barebones.s' exits via 'JMP $3D0' to warmstart DOS.
#
# You can get a blank DSK here
