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?
