Mainframe Computers Quotes

IBM existed a good 50 years before mainframes - we started with scales.

Today, your cell phone has more computer power than all of NASA back in 1969, when it placed two astronauts on the moon. Video games, which consume enormous amounts of computer power to simulate 3-D situations, use more computer power than mainframe computers of the previous decade. The Sony PlayStation of today, which costs $300, has the power of a military supercomputer of 1997, which cost millions of dollars.

I used to collect computer punch cards from the data centers.

There were no PCs when I started programming on computers.

UNIVAC: a device, which contained 20,000 vacuum tubes, occupied 1,500 square feet and weighed 40 tons; there was also a laptop version weighing 27 tons.

Right up till the 1980s, SF envisioned giant mainframe computers that ran everything remotely, that ingested huge amounts of information and regurgitated it in startling ways, and that behaved (or were programmed to behave) very much like human beings... Now we have 14-year-olds with more computing power on their desktops than existed in the entire world in 1960. But computers in fiction are still behaving in much the same way as they did in the Sixties. That's because in fiction [artificial intelligence] has to follow the laws of dramatic logic, just like human characters.

Every disruptive innovation is powered by a simplifying technology, and then the technology has to get embedded in a different kind of a business model. The first two decades of digital computing were characterized by the huge mainframe computers that filled a whole room, and they had to be operated by PhD Computer Scientists. It took the engineers at IBM about four years to design these mainframe computers because there were no rules. It was an intuitive art and just by trial and error and experimentation they would evolve to a computer that worked.

GIS started on mainframe computers; we could get one map every five to 10 hours, and if we made a mistake, it could take longer. In the early '90s, when people started buying PCs, we migrated to desktop software.
