Based on a system of SCM, realizing the input of digits (including of symbols and decimal) which is less than six bits, the system of SCM is composed of 80c196kc and matrix keyboard.

在一个单片机系统的基础之上，实现不多于六位数字(包括符号和小数点)的输入。该单片机系统由80c196 KC单片机和矩阵键盘电路组成。

Keyboard input from a decimal value, to determine its parity, if odd, the screen output 1, otherwise to 0.

从键盘输入1位十进制值，判断其奇偶性，若为奇数，在屏幕上输出1，否则为0。

Producer and microhouse master Matthew Herbert's own attention to detail shows here: Even though "Calculator" is chaotic, each resonant guitar strum and keyboard bleep remains as integral as a decimal place.
