Textronix TM515 Mainframe unit, Serial No.  B023347.  Comes with the following components: 1) FG 502 Function Generator.  Waveform frequency generator, Textronix Serial No B037609. 2) PS 503A Dual Power Supply, Textronix Serial No B029800. 3) SC 503 10 MHz Storage Oscilloscope, Textronix Serial No B010928 4) PG 506 Calibration Generator, Textronix Serial No B034852. The TM515 and plug-in modules were acquired second or third hand at one time from a government surplus sale, likely in the late 1990s or circa 2000.  The unit likely was built in the 1980s if not earlier.  I got the unit as part of a development project in the early to mid 2000s, has mostly been in lab storage and seen little use for the past 10 years.  There are calibration stickers on each component dated 1994 and 1996.  A front cover for the TM515 is not included.  The exterior has multiple scuff and dings marks, the controls are intact but used. This is clearly an used unit with cosmetic dings and wear. The TM515 unit and modules appear to be in working order, but I have only performed basic functionality tests.  All four of the modules power up and all controls knobs & switches are mechanically operable. The output of the FG502 waveform function generator showed sine, sawtooth, & square waves varying by frequency and amplitude in the SC503 oscilloscope.  Got signals from the PG506 in the oscilloscope as well.  Checked the voltage output levels of the PS503A dual power supply matched the control settings with a multimeter.  Did only basic checks of the SC503 oscilloscope, but both channels and trigger controls appear to be working.  Selling the TM515 as is.  The TM515 with the 4 modules weighs a total of 34 lbs, dimensions are 20” x 15” x 7”.
