[Software Engineering] TypingGame DL : 0: 打字游戏设计采用DOS功能调用（INT21H）中的AH=2CH得到系统时间，系统时间除模26得随机数，在此基础上加上基准字母，就可以得到随机字母。再利用BIOS功能调用中的INT10H AH=02H、06H、09H、0AH就可以控制字母的下降及判断字母的正确与否。利用8253的方式2进行计时和8259A中断就可以控制每10分钟打印，而打印则采用并行接口芯片8255A与中断芯片8259A以中断方式打印。-Typing game design using DOS function calls (INT21H) in the AH = 2CH get the system time, system time, except for 26 were random numbers, on this basis, with reference letters, it can be random letters. Re-use BIOS function calls in the INT10H AH = 02H, 06H, 09H, 0AH can control the decline in the letters and the letters to judge right or not. The use of 8253 means 2 for timing and 8259A interrupt can control every 10 minutes to print, while the print is applied parallel interface chip 8255A and 8259A interrupt chip to interrupt printing.
