IBM 1130

I wrote my first computer program in 1981 as a part of Programming course in School of Electrical Engineering, University of Belgrade.

That took place in this building behind the monument of Nikola Tesla.

The program was in Fortran, executed on IBM 1130 ("half past eleven"). Computer had 4K memory, punched card reader and primitive console

with big red "Emergency Button" (just bellow IBM label). Purpose of the program was computation of cosine function without referring to any library.
