[comp.ivideodisc] Info on ADAC VDR4120, OKTEL signal processor

Need info for ADAC videodisc file, OKTEL signal processor
One of the clinical departments at Duke has given me an ADAC VDR4120
videodisk storage rack, manufactured Jan '82, but with no documentation.
The guts are an OKTEL 3112-01 signal processor.  Neither of these companies
are in business at the California addresses marked on the chassis.
Can anyone supply me with info on the companies or hardware?
I need a programming info for the RS232 control port. Thanks in advance.
