This is a memory circuit that can store 2 different 3 bit binary codes. To set it for the first code, use the SPST switches, and then press the first NO push button at the top. To set it for the second code, use the SPST switches again, and then press the second NO push button at the top. To reset the first code, use the first NO push button at the bottom. To reset the second code, use the second NO push button at the bottom.
Any of the 2 codes that are set, will show on the output (simulated by the LED's) at the same time, so for example, if you set the 1st code to be: 101, and the 2nd code to be: 010, then the output will be 111, until one of the codes has been reset, then it will only show the code that has not yet been reset.
