Early on, Tek listed the 5000 mainfame and display unit seperately,

callibration terminal on the front.
One of the big advantages of the 577 over the 576 is the ease of
the CRT unit if it goes bad. You should be able to find a donor 5000scope
around $50. Despite the huge screens nobody wants them because of
