32x lead for mega drive 1?

i have a 32x here but no lead to connect it to the mega drive 1 is it possible to make one or buy one somewhere? if its possible to build one coul dyou give me the instructions on how to do it or list the codes for the parts on www.maplin.co.uk

i know this isnt much help to you, but when i got mine (32x) it came with a converter from md1>2, then the normal md2>32x cable

i have a question though, releated to it, should this cable output rgb( atm it only works in composite)
