norstar digital to analog converter for voice recording

[Richard1]

I am looking for information on a DAC part# 500-5068-103 rev. B made by digital techniques inc. back in the mid 90's.
The company no longer exists and I need the manual for it. I am using it for the recording of an attendent at a police station using a m7324 set.

Thanks
