DIY CD drive based on a computer CDROM

is there a way to control the cd-rom playing mode (start/stop/next/prev) without using the ide interface controller? what about a "dummy" portable cd player? how are its commands implemented? it's all about the built-in controller.. isn't it applicable to all cd drives (including cd-roms)?
i need at least a "play" button because my cd-rom drive has only the "eject" button. any help please?
 
Some CDROM chipsets/firmware support a play button.
I suppose if the traces were on the board for such a button
you might be in some luck...

I don't see how trying to graft another cd player onto a cdrom
would be easier than building one of the ide projects?
:xeye:

Why not get a cd rom with the play stop and ff Button ?

Well, i just have two teac cdroms which only have the eject button..

Is there any other method?! Do you have any cdrom drive schematics? The autoplay function are built inside the controller or it could be triggered from outside? I just need the "play" function for implementing the "repeat" mode..

Thanx everybuddy for the answers!

I bet you would pay no more than 2$ for a old 8x cd rom with ff button and eject : O ) that is what i did. and i also have a 48x one i see no sound difrence at all.

Possible solution to Red_Alert's problem

To Red_Alert:

I recently acquired a 24x Pioneer slot-in CD-ROM drive which only seemed to have an eject buttion. My intuiton told me that this couldn't be the whole story so I removed front cover and...TADAA! 😱 ...a second button was reveiled! Should you definitely look for one, too.
 
I've partly finished the MCLL CD-Rom controller. Here is a photo how it looks like
