Coin-operated shooting game machine circuit
Source: InternetPublisher:他们逼我做卧底 Keywords: Game console circuit counter BCD Updated: 2020/05/14
Circuit working principle: When the power is turned on, the current passes through the C1 and R1 differential circuit to
clear the counter D1, and only the Q0 terminal outputs a high level . The coin input signal clears the display circuit
and provides a counting pulse to D1, so the Q1 terminal of D1 outputs a high level ,
and the first round of the game is entered. The shot count counter D4 has the same structure as the hit count counter
D5. It is composed of two independent counters . 1Q0 to 1Q3 are the ones-digit BCD
code output terminals.
