Are you going to clone the sequencer part too?
Why don't you take a look at http://www.techrepairs.freeserve.co.uk 
There's a TB303 clone (only the synth part) complete with PCB and (good)
documentation. It's more than just a clone, it also features a suboctave
generator, HF modulation of the filter, adjustable slide time, a distortion
unit etc. Check it out.
