Analogue-sequencer

After a while of  my P3 circuit boards waiting for some attention I can now give them some 
time, ready to order parts and get the soldering iron switched on. However I'm wondering if 
the bill of parts is the same regardless of the board revision? How can I tell the board rev? 
The P3 chip has a sticker on it reading P3-2033 if that helps - Colin?

Many thanks in advance, looking forward to posting questions about aux events and all the 
other stuff that I can;'t wait to get into with the little beastie.

Yours, comfortably not "normal" human,

Pete.
