They may be tapes for a Sentry tester.  A development system was available
for VMS and there was a program to read and write TDX tapes for exchanging
data and programs with the tester.  If I remember correctly TDX stood for
Tester Data eXchange.
This may be a completely different TDX format.  Is there any other information
on the labels?
