These are Carbon Film Resistor with a value of 270k ohm 1/8W and tolerance of ±5%

There are four internal XOR gates in the IC 7486

LM339 - Low Power Quad Comparator Testing The slide switch is forThe LM339 consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2V to 36V, and VCC is at least 1. 5 V more positive than the input common mode voltage. The current drain is independent of the supply voltage. The outputs can be connected to other open collector outputs to
