Hidden Code exists in the ORCH-90 to produce a higher quality output.
Once you start the PAK, hit "SHIFT+ENTER" at the title screen. Once you
are at command, type the following (playing the William Tell default):
"S" + "ENTER"
"P" + "SHIFT+ENTER"

addressing CPU registers to run the 6809 at 2x speed.
"P" + "ENTER" will play at regular CPU speed. The difference should be
very noticable.
