looks like tektronix test system - the cpu box looks fully loaded
possibly with the fp11 and or 11/34c cache board, 2RLs and
a DEC 9 track tape drive, controllers, semi ram., two short racks.
you should be able to squeeze these into a single tall rack if you're
careful.
Should run Unix V7 quite nicely!
