    Do you have an idea how to get an used 7272 control unit ? It should be connected to an
    IBM /370 model 125 channel (not to the integrated interface, that is unusable)..
    This is for museum purposes, connecting 3270 terminal to BTAM batch programs.
    Thanks in advance for a nice answer.
