Hej Johannes,

I've been into 303:s since the late 80's and have done a fair bit of research about this. 
These are my findings; The audio circuitry and powersupply are fairly easy to clone, best bet is using the Oakley 3031 method with modern non-obsolete semiconductors, it gives a very authentic sound.
The sequencer is hard (but not impossible) to clone since there is no way to read the code from it.
You have to write your own software, easiest method is propably to use cheap PIC or AVR MCU's. To my ears half the magic of the "TB sound" is the sequencer so you have to clone the sequencer with all of it's weird quirks and functions.

I ended up buying a real 303 (actually two), there was no good soulution for the sequencer  part...
