Abstract
This paper describes the characteristics, instructions and peripheral devices of the NEAC-3100 (MC-1) and the NEAC-3200 computers which have been produced by Nippon Electric Co., Ltd., and which have been applied to laboratory data handling in physiology or bio-medical engineering, and to continuous monitoring systems in the clinical field.
The NEAC-3100 and the NEAC-3200 are integrated circuit general purpose digital computers with magnetic core memory, and are designed for both open-shop scientific application and real time on-line data processing and control.
The prototype of the NEAC-3100 central processor is the MC-1 computer. The NEAC-3100 is a 18-bit binary word machine with 2 μs cycle time and has an instruction repertoire of 45 commands.
On the other hand, the NEAC-3200 is a 16-bit binary word machine with 0.96 μs cycle time and has a flexible instruction repertoire of 88 commands.
Fast processing, modular design, a flexible I/O structure, and command repertoire make the NEAC-3100 and the NEAC-3200 adaptable to a broad variety of application in medicine both on-and off-line. This includes data reduction, process control, instrumentation, simulation and scientific computation.
