我厂将微型机应用在计算机外部设备方面,已有三年了,去年开始用在调试汉字打印机逻辑线路。汉打机线路由拼凑式改为微机控制式后,信息线增多,时间分配要求严格,使得老一套的调试方法无能为力了,所以要应用微机来进行调试。其原理为,将汉打机线路的地址,作为微机地址的扩充。其方法,按图1所示进行联线。由于汉打机线路是采用M6800型的,故调试用的微机亦用 M6800型的。把微机的母线(一般都能引出来)引到汉打机印制板的微处理器(已拔掉)插座上。利用程序自动查找故障,自动指示故障的地址。这种自动化的调试方法,不仅速度高,而且能确保质量。
I plant the microcomputer used in computer peripherals, has been for three years, started last year in debugging Chinese characters printer logic. Hank machine lines from patchwork to computer-controlled, the information line increases, the time allocation of strict requirements, making the old set of debugging methods can not do anything, so to use the computer to debug. The principle is that the address of Hankai machine line, as an extension of the computer address. The method, according to Figure 1 for connection. As the HANJI line is using M6800 type, it is also used to debug the computer M6800 type. The computer bus (usually leads to) Hankuang printed board microprocessor (unplugged) socket. Use the program to automatically find the fault, automatically indicate the address of the fault. This automated method of commissioning is not only fast but also ensures quality.
