It started life as a dream in 1947, ran its first test program in 1949 and played #music in 1950 or 1951.#CSIRAC was a very primitive computer by today’s standards. It was very slow (1,000 cycles per second); it did not have very much memory (about 2KB of RAM and 3KB of disk memory); it filled a room and; it had no display like a modern computer.Most output from CSIRAC was via punched paper tape that was later converted to text on another machine. The only familiar output device was a speaker (called the hooter), and it was used to track the progress of a program.Programmers would place a sound at the end of their program so they knew it had ended (this was known as a blurt), or they would program progress-indicator blurts into a program.With stock Ortofon 2M Red Cartridge, the Pro-Ject Debut Carbon gives a vibrant and clean sound quality which holds it’s own and makes it a remarkable turntable. For those purchasing a budget table, Pro-Ject Debut Carbon is the perfect one.
Despite being primitive, CSIRAC performed groundbreaking work, including running the calculations to find the centre of our galaxy in 1953, and for the engineering of our first skyscraper building.
