I think I actually have a possible solution to this little problem.
If you don't have that proprietary cable that is needed to connect the CD-ROM drive (DTL-H2510) to the developer board (DTL-H2500 or DTL-H2700) it is possible to make the two connect.
You will need to purchase 2 of these HD50 (or Micro D) expansion slots to 50 pin IDC cables such as this here or here or here (sorry I couldn't find any links other than ebay at the moment). You will also need to obtain a 50 pin IDC or SCSI ribbon cable commonly used with SCSI CD/DVD drives.
The expansion cover part will have to be removed by removing the screws on the HD 50 pin side. You may have saw off the liltle clips that keep the external cable attacthed...but that's certain better than trying to solder 50 wires to both the card and the cd-rom drive. Also since there is no notch on the connector to card or drive you need to make sure that don't reverse the pin mapping (pin 1 on the card connects to pin 40 on the drive.)
Now if I only had a solution for the external CD-ROM. (I have the drive but no cable. ) :banghead:
