作者曾在本刊1988年2期上刊登“PC—1500机窄行绘图程序可直接在宽行打印机上执行”的简讯,很快得到多家用户的采纳。现经过不断改进革新,研制出比火柴盒略大的硬件替代比较昂贵的CE—158接口,使用原有的磁带接口(而不占用60线总线接口),通过本接口直接向CE—515P宽行机传送程序指令,并由再次优化的窄行转宽行的机器语言相辅助(不会干扰机内常用程序),就能在主机上用窄行机绘图,程序随意选用窄行机上绘图或宽行机上绘图。性能可靠,安装使用极其简便,尤其能节省价值六百余元的CE—158接口的投资,
The author has published in the 2 issues of 1988 “PC-1500 machine narrow row drawing program can be executed directly in the wide-line printer,” the newsletter, quickly adopted by many users. Now through continuous improvement and innovation, developed slightly larger than the matchbox hardware instead of the more expensive CE-158 interface, the use of the original tape interface (without occupying 60 bus interface), through the interface directly to the CE-515P wide line Machine transfers program instructions and is aided by a re-optimized machine language for narrow lines to wide lines (without interfering with common programs in the machine), allowing drawing on narrow lines on a host computer. The program is free to draw on narrow lines or wide Plotting machine. Reliable performance, extremely easy to install and use, in particular, can save the investment of more than six hundred yuan CE-158 interface,
