Im the "lucky" owner of an old ARCHOS 24x Pcmcia cdrom.
and last night i took it apart (to bored :) ) and yes, as expected it was a
100% standard ATAPI Drive..
And Clever as i can be. i thought What would stop me from
hacking it to do for a harddrive insted!
there is no "intelligence" in the PCB inside the cdrom case,
so alle conversion ne

A couple of things:
1. In the April 2004 Elektor, there is a project for a PIC16F871 cdrom controller. This just allows selection and playback of selected tracks - the audio output is used for the sound output. Remeber though that almost all cdrom's have a digital bitstream output - same format as S/PDIF, just needs level (...)

cdrom AUDIO controller using Atmel is one project version_2 present to friends.
I've recovered the, ehem, corrupted Eagle files which couldn't be opened. Additionally I've printed the schematics in PDF files for those of you not possessing Eagle.
Btw. some infos are missing: the connections between the boards, some device

I have a problem with a GCR-8521B (Sony CXD3045R controller) cdrom firmw. v1.02, controlled by a custom (8051 derivate) controller.
It seems that the cdrom don't recognize the ATA Packet BBh command (set cd speed).
The other ATAPI commands works correctly (play audio msf, read toc, mode sense etc.)
and also (...)

ok... what about +5V and +12V for hdd (cdrom)?? it need external power supply also?? I think USB can give not more than 500mA!! hmm... or it can be take from computer, but if someone don't want open computer?? eh... :(

interface by IDE
The following article might not point directly to the questions you ask but you may take a look and probably you would find some tips to start your project:
Standalone controller for an IDE cdrom Drive

that depends on what you're going to design.
There are ATA(HDD), ATAPI(CD,DVD,MO) devices
So, if your device is trying to access cdrom - Spec over ATA/ATAPI-4 is required
And, there are 3 kind of access timing
PIO, (S)MDMA, UDMA
Speed is also different...
My suggestion is read ATA-2 spec first, that's enough for old HDD if you do

The code should be provided with the kit. Look at the cdrom that should have come with it.

It depend on the purpose, you are intending the software for. You can e. g. burn it to a cdrom and use the CD to smash mosquitos. In this case, any version would fit. Or you may intend to use the Keil compiler to write programs for a processor. In this case, you should know about the processor type.

I have some stepper motor's from hard disk and cdrom's(I heard that they are not stepper but DC brushless=??). I want to make controller for this 3 motors.
Which circuit is the easiest and cheapest to make DIY controller for this 3 motor's. I would like to make usb driver not LPT(because I don't have LPT port on my notebook
