Looking for Zilog S8000 stuff

Hey all -- Got myself a Zilog S8000 Model 31 in operable condition. It's a bit of a mongrel (I'll get into that later) and of course the drives have been wiped. I know this is a long shot, but does anyone happen to have any media for this thing, in any format? There doesn't appear to be much out on the 'net about this thing so I'm guessing that software is going to be hard to come by, but I have to try, right? I'm also looking for an ECC controller for this thing -- when I got it it had several random (and possibly mutually incompatible) boards installed in random slots. I have one 1mb ECC board (no controller), one 1mb parity memory board (that I have no documentation for -- nothing on Bitsavers matches this thing) and one 128K parity board that appears to have been upgraded to 512K (4 rows of 18 64kbit DRAMs). There's also an "I/O Processor" board (with its own Z8001 cpu) which I have no information on. I'll be dumping the EPROMs from this once I get my stuff unpacked from my recent move, I can also take pictures of stuff if anyone's interested... Thanks as always, Josh
