seeking docs for Monlithic Systems 303-0158 unibus memory

[Fritz Mueller via cctalk]

Subject line says it all -- I'm working on a restoration that includes one of 
these, and it looks as if it needs some troubleshooting/repair.  I didn't see 
docs posted at Bitsavers.  Anybody have a manual squirreled away?

    cheers,
