Old Roland Drum Machine

[Matthew Porth]

        Hello,
     
        This is my first post to this list and I have enjoyed what I have 
     read so far, the archive is very interesting. I am interested in 
     analogue electronics, but am no purist, I have FM keyboards that make 
     wonderful sounds :)
     
        Anyway, I hope my first message is too much of a daft one but there 
     you go. I have a Roland 606 drum machine that I use to generate 
     allsorts of noise. Put through a small amount of overdrive, a nice 
     analogue delay (the worse, the better as it were) or a digital pitch 
     shifter and it makes a nice rhythmic backdrop.
     
        I couldn't find this info in the archive but what I need to know is 
     the pin outs on the roland sync socket. From the circuit board I get 
     the feeling that there is some kind of beat advance signal (I need to 
     sync this to a PC based software synth). Could someone furnish me with 
     the details please. Also are the schematics for the 606 on the net 
     anywhere???
     
        One more question, In the archive someone had been studying the 
     kick circuitry of both the 808 and 606 with a view to boosting the 606 
     kick a little, anyone else know anymore about this??? I would be most 
     interested. I am sure the kick on the 606 is not as loud as it used to 
     be, abuse and overuse perhaps ;)
     
        Thanks,
     
                Matthew.
