György Sándor

In September 1969, he joined the Computer Reactor Control Department of the Atomic Energy Research Institute of the Central Physics Research Institute (KFKI) of the Hungarian Academy of Sciences. His first work was the hardware design, project management and software development of the interface unit of the hybrid computer system based on the TPA minicomputer and the MEDA 80T analog computer. At the same time (within the framework of the Intercosmos space research program) at the Budapest University of Technology (BME) he wrote a program in assembler on a LINC-12 computer for the high-precision adjustment and final inspection of R-2R ladder networks. This was followed by the design of the 3-mode electronics controlling the intervention in the R-10-based measurement data acquisition and control computer system. With this device, the group was the first in Europe to implement DDC (Direct Digital Control) mode nuclear reactor control.

Under his leadership, the 200-channel real-time measurement system for the reactor compartment tightness control of units 1 and 2 of the Paks Nuclear Power Plant (PAV) was designed and built - based on TPA/i CAMAC and RT-BASIC. For units 1 and 2 of PAV, he adapted the nuclear data acquisition subsystem to the central data acquisition machine. In order to ensure the necessary high reliability, he also developed the automatic switchover solution for redundant systems.
In 1986, he participated in the development of the PAV nuclear power plant training simulator in Helsinki, programming the training subsystem in RT Fortran.

In 1987, he switched to the world of personal computers, PCs, and small business. He worked in the small cooperatives Adatrend, Next, and Montana, where - in addition to his main job - he began collecting documentation for obsolete PCs and their components, as well as large program systems.

From 1998, he worked as an IT manager at the subsidiaries Hydro Hungary Kft. and then Alcatel Hungary Kft. He retired in 2007.

He joined the activities of the Informatics History Forum (iTF) in 2009. He donated a significant part of his PC collection to the Szeged Informatics Collection, László Kutor and Károly Nagy.
