Tektronix's  TM-500 Series test equipment

The reason for several of the same type of modules was that there were
4 benches setup and each did a different job.  However, as displayed
the modules were randomly placed into the various cabinets after testing.

Manuals for each unit are on disc in pdf format. All include the operational manual
and most include the schematics and service literature as well
.
