Sure, here is the assembly code converted into binary machine code:

Address | Machine Code | Assembly Code
x3000   | 0010010000000001 | LD R0, ASCII

x300C   | 1111111000000110 | DDR .FILL xFE06

Note that each line of assembly code is converted into a 16-bit binary machine code instruction. The address of each instruction is shown in the first column, followed by the machine code in the second column, and the original assembly code in the third column. The data values (.FILL directives) are simply represented in binary form.
