In March 2008, I was lucky enough to snag this system off eBay less than 3 hours after it'd been listed.
Unfortunately, since the system was decomissioned after use in a government agency, it didn't come with any drives. This is pretty standard practice and not a big deal except that the DS20L requires a slim (laptop style) CD-ROM drive with a strange JAE 50 Pin interface. I tried and couldn't find a double ended JAE cable anywhere except some 3rd party HP parts dealers. They wouldn't sell it for less than about $30.
I also was unable to find the hard drive assembly rails necessary to secure the internal SCSI drive. Another issue is that the system only has a single 4 pin molex power connector. The JAE cable provides the data interface and power to the CD-ROM, so if you have this cable, one 4 pin molex is all that is needed. Since this JAE cable is no where to be found now, I bought a molex splitter to power the SCSI drive and a standard desktop CD-ROM drive connected to the internal IDE during the Linux installation.
Unless I find a pressing need for a CD-ROM drive after the operating system installation, I'll buy a standard laptop CD-ROM drive and a JAE to IDE adapter commonly found on eBay.
For reference, the JAE cable and hard drive assembly kit are Compaq part numbers:
- 17-05140-01 - CABLE ASSY,FLAT,CDROM,50CND,(2)POL RCPT
- 17-05142-01 - Harness Assembly, Disk Power, 4 Cond, (2) Receptor Connector
I think one reason I had such trouble finding these parts was because I was using Compaq part numbers instead of HP part numbers. These appear to be the relevant HP part numbers:
- 3X-PBXRZ-AA: 600MB 24X slim CD-ROM drive and installation kit
- CK-DS20L-AA: One drop DS20L SCSI cable kit
- 3X-RZ3ES-SA: 18,2GB 10000rpm Ultra3 SCSI 80 pin SCA2 HDD DS20L drive
- 3X-RZ3FS-SA: 36,4GB 10000rpm Ultra3 SCSI 80 pin SCA2 HDD DS20L drive
- 3X-RZ3GS-SA: 72,8GB 10000rpm Ultra3 SCSI 80 pin SCA2 HDD DS20L drive
Addendum: 18 July 2008
I found another DS20L owner who bought four of these systems when a local tech center was decommissioned. One of his is nonfunctional, and he was kind enough to (1) put up with my questions and (2) send me the parts I didn't have including:
- The weird 50 pin CDROM cable
- A slim Samsung CDROM drive
- CDROM drive backplane
- Hard drive mounting kit
- Short SCSI cable for the hard drive
- 80 - 68 pin SCSI backplane
