Working memory was realised with a magnetic drum memory providing 4096 words of 33 bits. Moreover, the system was comprised of a command desk with keyboard, lamp array for displaying operational states, switches for locking certain tracks of the drum memory, two paper tape readers and one puncher, and a typewriter-like printer. It needed about 9 sqm space in an air conditioned and noise insulated room. Power consumption was 1500 VA.
The system could be programmed in pure machine code, or in interpreted pseudo-code using a program called GIPS I, Gleitkomma-Interpretationssystem einfacher Wortl鋘ge, i.e. floating point interpretation system with single word length. It simulates floating point arithmetics as well as a number of pseudo data registers. The GIPS I interpreter had to be read into memory before use.
Moreover, it was possible to program the system in PS 2, which probably meant programming language 2. It was developed by VEB engineers. This language implemented various data types, mathematical operations, I/O commands, and control statements equivalent to GOTO, IF...THEN GOTO, labels, subroutines, and FOR-loops. The source program had first to be punched on paper tape, and then compiled. As the PS 2 compiler occupied the complete memory, the resulting object code (in GIPS I format) was immediately punched out on paper tape. After that, the object code could be read and run with the GIPS I interpreter in memory.
