众所周知,使用计算机算题必须在上机之前把源程序和数据穿成二进制编码的纸带,然后再通过光电输入机输到主机去。厂方为TO-6机提供穿孔用的是CFX-5型穿复校机,该机无印字的功能,按错了键穿错了孔不能及时发现,使用者感到很不方便。为此我们考虑利用已有的NOVA 840使用的ASR 33电传机穿纸带。但CFX-5穿复校机采用“奇校”,即穿出的纸带的每一排全部为奇数个孔,代码为8单位“自然码”编码,而ASR 33电传机
As we all know, the use of computer code must be put on the machine before the source code and data into a binary coded tape, and then lost through the optical input machine to the host. The factory for the TO-6 machine to provide perforation is CFX-5-type wear school machine, the machine does not print the function, press the wrong button to wear the wrong hole can not be found in time, the user feels very inconvenient. For this reason we consider using the existing NOVA 840 ASR 33 fax machine to wear tape. However, the CFX-5 wearable machine with “odd school”, that is, each row of paper tape out of all odd-numbered holes, the code is 8 units “natural code” coding, and ASR 33 fax machine
