摘要

今年是英国首个面向学校的微机接口诞生十周年。这是一台Commodore设备，它有四个数字输入和四个数字输出，通过一组简单的控制程序从PET 2001微型计算机的用户端口运行。PET 2001本身有8K的内存，它的屏幕分辨率是4000点，它将程序存储在盒式磁带上。

Microcomputer interfacing—past developments, possible ways forward

This year marks the tenth anniversary in Britain of the first microcomputer interface for schools. This was a Commodore device, which had four digital inputs and four digital outputs and ran from the user port of the PET 2001 microcomputer via a set of simple control programs. The PET 2001 itself had 8K of RAM, its screen resolution was 4000 dots and it stored programs on cassette tape.
