Sequential circuits samplers

So, I had the floppy cable in upside down, but now I get a Lh (Locked
Head) message.  I'm buying the Teac 235HF drive and hopefully that
will be that.  Also, I'm hoping that I may be able to add individual
outs on this ala the tr-606 with the switching jacks.  I read
something about this on a search, but saw no post revealing the
results.  Has anyone successfully done this?  I don't want to mess
with the traces on the PCB so this seems like the only way I'll get
individual outs.  I will also save money.  I could really use the
schematics as well if anyone has them.
