I'm patiently awaiting a good ATAPI ODD emulator as well, but for a lot of purposes the iodd2531 is one of my favorite things i've ever owned. Not internal but at least it can appear to the PC as a USB-CD if you wish...

Ooh thanks for letting me know about this! I can use it with some VIA mini-ITX systems I have that present USB storage devices to DOS. Not sure if audio will work though.

For what it's worth, the SCSI2SD card can also emulate a CDROM device. It's not useful for general purpose retro computing because you have to basically dd your image file to a specific location on the SD card, but it works pretty well for more 'permanent' use of CD images such as operating system install discs.

IE to "change discs" you have to power off your target computer, move the SD card to a more modern computer that has something like dd, rewrite your new CD image to the correct spot on the card, and then move it back to the first system and boot up.

Currently DOS will just see it as a plain ATAPI drive - you need to connect something via USB if you want to swap disks/etc. (which could be the DOS machine itself, if you could get USB CDC serial devices working under it).

However, I did install Turbo Pascal (the first language I ever really learned) as I wanted to make a utility you could run in DOS to switch images/etc. from inside the host machine, but I didn't have much time to actually work on that yet!

The most important question for me is: can I boot from the device? I have a lot of mainboards, which do not offer to boot from USB. I always have to attach an IDE-CD-Rom to install an OS. 200$ is quite expensive, but it's worth to finally get rid of those ugly CDs....
