You may "How to blink a light extremely inefficiently 10 different ways." ;-)

Seriously, not even one Asm example? If you have a PC that has a parallel port and can boot to DOS, you can stick a LED in series with a 100-ohm resistor across pins 2(+) and 18(-) and do this:

        mov dx, 378h
        xor ax, ax
    blinkloop:
        out dx, al
        mov cx, 36
        call delay
        not ax
        jmp blinkloop

    delay:
        hlt
        loop delay
        ret

I find it somewhat amazing that this program, in Assembly, is actually shorter than the 10 HLL programs in the article.
