You don't need a schematic to know about the LM3900's, as later modules
were unpotted.  I've got two broken ones sitting on my bench, awaiting 
the return of my Odyssey schematics so I can figure out the I/O.

Module schematics for Arp stuff are hard to locate - Timothy Smith 
promised me a set when he got ahold of some, but I don't know if he ever 
got them.  Phil Cirrocco (sp?) may have them as well.

I'll let you know if I figure out the topology.
