I have listed in the Buy/sell a CD Player that can be added to a Rowe R90-R94. I know this section isn't for Buy/Sell, but this is a pretty specific item for Jukeboxes.
http://forum.arcadecontrols.com/index.php?topic=95236.msg1002386A Rowe 45 R90-R94 can add a CD player and make it into a 45/CD Combo. As best I can understand, these were at the beginning of CDs. They ran both 45s and CD in the same jukebox. Either a 6 CD Pioneer, or a 10 CD Sony. It's actually a neat setup. I have a similar setup in an R90. That uses the Sony. It will play burned CDRs. So it can have 200 selections of 45s, plus whatever you want to burn for the 10 CDs.
"IF" you EPROM is the right version, and
"IF" you have the correct model Sony, and
"IF" you can make the cables
You can hard wire in a CD player without the interface board. It took me a long time to make that work, and I'll post directions at some point in the future. Getting the right model will probably be as much as this Pioneer kit, so if you want to just get something to plug and play, I have that in the buy/sell.
I'm not sure what model Sony's work, but I'll post pics of what I got to work for me.
