Any one know of a simple op-amp circuit i can use to up the output power on the cd rom * stock * OR a simple dac circuit to use with a cd rom ?

I got it from here for simple OPamp.

For Dac I use TDA1543 x 4 you can search in this digital forum so many schematics.

I'll have to look it up to confirm but it depends where the text is encoded. Some of it is accessible through the P-W subcode but I think the larger CD Text region requires a controller with CD Text capability.

what did that start out life as?

i had 3 cd roms i listened to all of them then this one became it. I disassembled it and kept the rubber isolators on the cd module and now here it sit's now i want to build a audio buffer and see what it sounds like then a digital dac .. if that works out then go from there to a nice case top-loaded then a display : O )

Well as i listen to this cd player more and more i like it a-lot. My only problem is i cant tell what track i'm on or pause ir ot skip back only forward and play. Im wondering what my steps are ( im on a mac but have access to a pc and a programer maybe ) to get a display to work on this ide cd rom with out killing the sound from the audio out port. i can build every thing with no problems just need the path to follow..

I have a Optrex red display brand new just dim.

Model number is C-51505 Tm005 If pictures are needed i can provide them..
