This article describes a very simple but quite powerful 32-bit architecture ideally suited for experimental and educational purposes in computer architecture design. It employs a very orthogonal instruction set in conjunction with 16 general purpose registers and a simple interrupt capability. It was developed at the University of Mainz, Germany and a prototype using standard TTL-circuits is being developed --- large parts of the microcode are written and simple assembler and an emulator written in FORTRAN already exists.
