Vintage Texas Instruments TI Cassette Tape Program Recorder PHP-2700.  Comes with AC power cord, Cassette Interface Cable, instruction manual, and original box.  Tested - works, meaning that it powers on and reacts when buttons are pressed.  I have not hooked it up to test it.  Clean; no defects. One of the male ends of the Cassette Interface Cable shows some light surface corrosion (see pic).  Box has wear from being used to store the machine in.  Cords have some slight discoloration (yellowing) in places.
