I still have to get the music into the shop tho!

My pool bar player is actually in the shop. It is wired through the wall to the
monitor and keyboard in the pool bar. I also have speakers in the shop tho. My
"keyboard" is actually a Seeburg 3W1 wallbox running through a keyboard card.
This is a DOS player (MPXPLAY) that can select songs by number. Perfect match
for a jukebox. It defaults to random play but that is all configuration
options.
I run the same software in the cars. "Key on" to "music" in about 15 seconds,
no crashes and no shutdown.
