電気・電子・情報系の学生にノイマン型コンピュータの動作原理を教えるために,実機を用いた機械語教育を行うことが提唱されてきた.しかし,現在のコンピュータ・システムは教育用には高度で複雑すぎる.そこで,筆者らは,高専や大学において,機械語教育に使用する演習用のマイコンを設計・開発した.開発したマイコンが備える,内部を2 進数で観察できるコンソールパネル,命令セットアーキテクチャ,入出力装置,クロス開発環境は,どれも教育用に配慮がされたものである.また,学生が個人で所有できるように小型・安価に実装した.実際に徳山工業高等専門学校の授業で4 年間使用し,教育効果があることが判明した.To teach students the principle of the von Neumann窶鍍ype computer, the machine language education with a real computer has been advocated conventionally. However, present computer systems are too advanced and complex to educate them. According to the demand for the higher education, the authors have designed and implemented an educational microcomputer system to satisfy the demand. The implemented computer has a console panel, that can be used to observe the inside, a set of instructions, I/O devices and cross development environments that are appropriate for education. Moreover, it has been implemented small size and at a low price so that the student might own it individually. It has been found out that there is a feasible education effect because of the practical usage in some classes for four years at Tokuyama College of Technology.

According to the rapid progress in the performance of the microprocessors and their cost-down, the Engineering Work Station (EWS) and Personal Computer (PC) have been applied to the various problems in the computational mechanics. The finite element method (FEM) is the relatively popular technique of computational analyses among various numerical methods which are aided by the EWS and the PC. The FEM will require the preprocessing to discretize the analyzed domain into triangles. In the paper, we shall present the development of highly interactive and portable pre-processors for 2-D FEM analysis. The present system works on X Window System Version 11 Release 5 (X11R5) on EWSs. Since that tool makes the best use of Graphical User Interface (GUI), even a novice user can make the mesh data and visualize the calculated results readily. The high portability of this GUI is ensured because we adopted the licensefree Athena Widget set as the fundamental GUI gadgets.
