Paper Abstract

This paper describes a new microprocessor system, to be known as the "4MS" (4.2m Microprocessor System), for instrument control which is primarily intended for the instrumentation being developed for the new observatory in La Palma, Canary Islands. The Royal Greenwich Observatory Electronics Department intend to supply this system to interested Observatory and University groups throughout the U.K. and Europe. The system to be described is an integrated hardware and software package utilising a simple and highly reliable technique for the generation of "target" software without the process of target compilation. Traditionally the transfer of software from a development system to a target system has been a process subject to errors where fault finding can be a very time consuming process, this step has been virtually eliminated. The hardware is based on a series of Eurocard modules compatible with the G-64 bus and the hardware forms both the development system and the target system. The software is based on the language polyFORTH and is supplied as a TURN-KEY system having a system console and disk drives. In this day and age, cost can be a significant factor in instrument design, this package eases this problem because the cost of a separate development system has been dramatically reduced.
