Check out this guy's page for all of the info on it (and then some). http://www.onfreq.com/syntorx/syntorx9k/index.html

Is there an updated link to that, when I click it it just goes to a blank page. Yes I know it's years old, but if there are other resources that contain similar info, please post.

Also, how does one get a historical "file" on a DPS unit to know exactly what equipment it had when in service?
