  "A late-1980s tour of QRS Music's piano roll manufacturing facility
in Buffalo, New York, originally aired on the TVOntario children's show
'The Acme School of Stuff'."

Especially interesting is watching Rudy Martin working at the stop-tab
arranging piano (later replaced by computers) and the use of Apple II
computers to drive the perforating machines.
