 It's not pretty (yet) but this schematic is legible. <guilt> I uploaded a better image, still imperfect but better. </guilt> Might want to ask some questions, a one page schematic will be easier to read.

 ==Proprietary SSM 2000 - mystery chip==
 Check out the schematic shortly before the audio out. You'll find a 16 pin DIP chip marked SSM 2000. It is billed as a 'propitiatory chip' I doubt that Solid State Music was a company with enough capital nor demand to create a custom chip for the SB1. I suspect it was a re branded chip of some sort. In the schematic it looks like a couple op amps with null offsets like LM741.  Note that the envelope comes into the opamp as a null offset while the waveform comes in the + input.
 Can anyone hazard a guess as to what this chip is? I suspect it may be a problem on my two remaining non functioning SB1 boards. Can we match the pinout?

-This is the 'studio' I used to create the following recording. It's an Imsai S-100 running Josh Bendason's JAIR CPU with four (4) SB1 boards. Note: One card in extender. The music is encoded with eight (8) channels. I recorded the first four channels through a Mackie ProFx12 mixer with alternating channels primarily panned left and right and recorded using audacity on Windows 7. I then readdressed the four SB1 cards to channels four through seven recording another stereo track that was synced with the first track and exported to create an eight channel recording of Scott Joplin [[:File:SSM SB1 Enter ch 0-7.mp3|The Entertainer.]]. (<-- click the file name in the next screen to play, while I think about installing an mp3 player in my mediawiki)

 '''Wanted to buy''' I'd like to have a full set of eight (8) SB1 boards. Most of the .MUS music files I have utilize up to the full compliment of eight boards to play all channels in real time.. Please use the [http://www.theretrowagon.com/contact/ contact form] to communicate with me if you have any SB1 cards you're willing to part with.
