- I was at a computer flea market this afternoon, and a dealer swore up
- and down that it was an IDE interface of some kind. He claimed that you just
- use the secondary IDE address, and treat it like a normal disk drive. He also
- said that you cannot plug the Mitsumi into a regular IDE board, but you have to
- use the board that it comes with, which implies that it is not plug compatible
- with an IDE disk.
-
- This all sounds like someone would need to try and hack the kernel so
- that it looks at the secondary IDE address. Once you have that working, I
- think you could just "mount -t iso9660 /dev/hdc /mnt" and you should be all
- set.

- For what it is worth, aI saw a NEC 83 scsi cdrom drive going for 300$
- this afternoon. The dual speed drives are still more expensive, but might
- prove worth it if people want to use the cdrom heavily.
