DIY CD drive based on a computer CDROM

[ugolinima]

Dear pradit_p,
thank you very much. I will contact you by email in the next days in order to recive from you your .hex file. I will also be very happy to make a donation as you suggest.
What are the main differences between yout board and the original Mucop one?
Regards,
Ugolinima

Hi ugolinima
Mucop original didn't have LCD display function and Remote control function but my board have.
But for Free Hex file will have LCD display function but didn't have remote function.
If you want to got Hex file please email me to let me know your email address to send you Hex file.
I decided to send 1 time a month for interested people to have fun with DIY CDplayer from CDROM. And also want to know at least your email .

Regards,
Pradit

Cool this thread re-appears. I have yesterday Build a power-supply 5V and 12V for a cd-rom and attached it to my stereo having 3 cd players plus this computer cd rom i have to say that the computer cd rom sounds best.. Only fed audio with left and right output at the cd into a tube pre-amp to a tube power amp with my new speakers it sounds better than a store bought cd player.. So far.

Now i want to build a dac the something that can pause the cd player and maybe a small buffer to up the cd-roms out put a little. It's kinda weak on the output..

BTW, I have add remote function to my cd-rom player (using RC5 decode)

Would any of these controllers work with the NEC Multispin 602 (6Xi or e)?

[davesaudio]

those are scsi , are they not?

the above all have "ide like" interfaces

although the atapi commands are a scsi subset I don't
know that the interface would work without some
modifications?

All of those are using IDE Interface to control CD-Rom Drive. What control interface of NEC Multispin 602?

I'm planning on building a transport, and was thinking of using a gutted NEC 602 in the case below donated from my old AA transport. Don't know of a newer IDE-based CD-ROM drive that I could gut and use - anyone know? The NEC has that nice solid metal chassis. It is that or a Philips CD-PRO2, but they're so so expensive. Problem with the NEC is the display board (too small for my application and not enough information for me, like track number, etc). Take a look at the pics and I'd love some advice! The box is perfect for a top-loader, and has internal metal shielding around some of the boards. The controller board and display board were in one box, and the mechanism in another.

It is SCSI, and is well built and suited for a CD transport, but the display that it has (both size and the information) are poor for CD use.

If you accept that whatever route you take some additional electronics will be required, then you might as well stick with the '602 and channel the effort into adding a better display. That the information is already there is shown by the limited display it has. It is just that NEC chose not to display it. The subcode data that carries all the disc information is available from the cdrom controller,either directly or embedded in the SPDIF datastream.
