Here's a first principles tutorial. You can program your emulator by
doing the same thing that folks did back in the 1970's
programming the Altair 8800:
entering the raw octal instructions. The only
difference is we're using printf instead of those flip
switches. Here's a simple program to get started:
printf '\100\353\375' >prog.bin blinkenlights.com -rt prog.bin
You should then see your program appear in a terminal interface that looks like the following:
You can then press the s key to step through your program.
Be sure to make the terminal font size as small as possible, and to
maximize the terminal window, so that you see all the panels. It’s also
a good idea to enable SSH compression when accessing Linux via the net,
since it’ll increase your framerate.
Here’s how you can build programs using the GNU Assembler and Linker.
echo ' .code16 .globl _start _start: dec %ax jmp _start ' | as -o prog.o ld -static --oformat=binary prog.o -o prog.bin ./emulator.com -rt prog.bin
