"We’ve Heard of ROLMs; But What the Heck is a Dual-ROLM? Recollections of a Pioneering Real-Time Control System" is a document by a "William E. Richardson" that I found on archive.computerhistory.org by accident during a Google search, which appears to be listed nowhere. It is an absolutely fascinating read about an extremely obscure (meaningless to the general public) watershed event in computing.
