I've got all of the Concussor percussion modules and a Vermona DRM1, 
the Concussor modules are exact clones of 808, 909 and CR-78 
circuitry, even down to using correct japanese transistors, but they 
have a few extra mods and controls to increase the tonal ranges. 
There are two things to bear in mind though, the trigger pulse 
length can alter the sounds a bit, use 1ms pulse and they will sound 
very near to Roland. Other thing is they run from +/- 12v supply 
rather than +/-15v that the 808 and 909 used, this has a slight 
bearing on the sound too, makes them seem a little bit softer to me. 
The DRM1 can make some noises that the AS modules can't and they do 
complement each other quite well.

I sequence these modules from my Schaltwerk sequencer, but the 
Schaltwerk needs some trigger outputs adding to work with them, the 
gate outs don't trigger successfully. My Schaltwerk trigger mod pcb 
and circuit is in the files area of Schaltwerk yahoogroup, this 
gives the correct 1ms long pulses that these modules work best with.
