Looking to make a 'sinowealth' ic programmer cable (r232 preferably!)

Hello all, I have undertaken a challenge by freind to use only parts from broken equipment already in my possesion to make something amazing! (i thought id better clarify this befre people start replying 'easier to buy a pic or atmel chip) the only reprogrammable chip in my heap is the SINOWEALTH SM69P26K which i understand is an14k x 4bit mc, does anyone know where to find a schemat or how i can wire a basic R232 programmer cable to connect with? Macgyver status awaits! Thankyou for your time in advance!
