This piece illustrates the "packaging" arrangement of the logic modules. These three mounting panels, 1: MAR Control 1, 2: MAR-XR, bit n+1, 3: MAR-XR, bit n, illustrate the hardware construction of the TX-0 Computer. The dual register panels each have two large plug-in-units called the flip-flop modules and each flip-flop package serves as one binary digit of a register. The multi-colored plug-in tubular bottles each contain 1, 2, or 3 transistors. These standard gates are wired together on the back of the panel as the logic which controls the state of the corresponding flip-flop. The upper control panel has the logic which gates the time pulses to become the appropriate clear and load pulses. The TX-0 computer was designed and constructed at Lincoln Laboratory and used at EE/RLE until 1975. TX-0 was one of the first transistorized working computers.
