DACICC-1 (1963) electronic computer, in complete configuration
The DACICC-200 computer (1968), installed at Bucharest (1969), operated by engineers Petre Soreanu, Mircea Bocu and Gheorghe Farkas

Some of the first electronic computers in Romania built here:

  • MARICA, ’59, relay computer;
  • DACICC-1, ’63, 3rd in Romania, but 1st with transistors & RAM memory;
  • DACICC-200, ’68, most powerful Romanian computer; 1st with OS & compiler.

The first ionic implantation device from Romania

In the seventies was constructed a ionic implantation device.

It was subsequently improved at ITC, in 1976.
