Ok, since you are pushing for a taker, I'll bite - also assuming you also disallow
stack (cuz that would be obvious), here's a simple way to do it (8080 code):

    ANI 15
    SUI 10
    SBI 0
    ADI 11
    SBI 10
    ADI 11
    SBI 10
    ADI 11
    SBI 10
    ADI 11
    SBI 10
    ADI 11
    SBI 10
    ADI 11
    SBI 10
    ADI '0'+11

Cheers,
Dave
