随着微型计算机在我国各行各业的普及和计算机辅助设计(CAD)的不断发展,微型计算机辅助绘图的重要性日渐突出。计算机辅助绘图不仅提高了人的工作效率,同时也改善了绘图精度。因此微型计算机辅助绘图是一个很受欢迎的课题。我们在Cromemco-D系列微型计算机上,完成了和SR-6602六笔智能绘图机的联接。同时配置了一个基本绘图软件库。通过一段时间的实践证明,这种配置不仅提高了Cromemco-D机的使用效率及应用面,并且能够完成一般计算机辅助设计及绘图任务。在联接过程中,我们采用了并行接口,其目的在于能使用Cromemco-D机系统中原有的打印机驱动程序。 SR-6602的并行接口共有16根输入输出信号线。
With the popularity of microcomputers in all walks of life in our country and the continuous development of computer-aided design (CAD), the importance of microcomputers aided drawing has become increasingly prominent. Computer-aided drawing not only improves people’s work efficiency, but also improves drawing accuracy. Microcomputer-assisted drawing is therefore a very welcome topic. We have done a link with the SR-6602 six-pen smart plotter on the Cromemco-D series of microcomputers. At the same time configured a basic drawing software library. After a period of practice has proved that this configuration not only improves the Cromemco-D machine efficiency and application of surface, and to complete the general computer-aided design and mapping tasks. During the join process, we used a parallel interface that aimed to use the original printer driver in the Cromemco-D system. SR-6602’s parallel interface has a total of 16 input and output signal lines.
