A program that inputs musical scores and outputs sound using a PDP-8 either by radio frequency interference, or a special IOT instruction that would be implemented in hardware.
A collection of scores is included.
Originally distributed as DECUS 8-804.
Upstream source: Vince Slyngstad's DECUS archive 8-804.
There is another set of sources on the dbit ftp site.
The score files are also available in an RK05 image at Dave Gesswein's Archive: diag-games-kermit.rk05.
I'm not quite sure which source I used. This set of sources includes a patch to CCL
PLAYOV, (that may not work for some versions of CCL) to add a
SIMH does not have support to get useful sound from this program. However Randy Dawson in 2017 came up with a hack that enabled SIMH to output something that was post-processed into audible sound.
A detailed instruction manual can be found in the file decus-8-884.pdf.

Author: Richard Wilson and others Digital Equipment Corporation, Maynard, MA Operating System: Paper Tape or OS/8
Source Language: PAL-8
Memory Required: 4K
MUSIC is a program which will play music in four part harmony on any PDP-8 family core memory computer, except the 8/S or PDP-12. The music to be played is input to the program as a standard OS/8 ASCII file. The music may be picked up by the use of an AM radio, or by a simple interface. The OS/8 distribution media include the source of the player, which can be customized for various configurations, along with approximately 45 minutes of music, such as Joplin, Bach, Beetho- ven, movie tunes, etc.
The binary paper tape is intended for any 1.5 microsecond PDP-8, and runs in 4K, but will only play short tunes. Several short tunes are available on paper tape.
