The company I worked for grew and the System 10 couldn´t. So we looked around. There once was a computer company named Digital. There´s a saying that Digital invented the minicomputer. They had a family of computers under the name PDP, and this was to become my new acquaintance. On this type of computer you could optionally add a CPU panel. When creating the OS you could set a flag to get a Nul-job. It´s only purpose was to sequentially light the lower row of LED´s on this CPU panel. Well, I must admit that it was more than once I entered the computer room without turning on the lights, just to have a look at the rolling lights. Yeah, maybe I´m a disturbed personality.
  By observing the lights on the Nul-job you could actually see if something was wrong with the ongoing work on the computer. I once run across a professor who was so old that he had worked with a computer made with relays. He confided me that he had improved his musical talent by listening to the rhythms of that computer. He developed such a talent that he could hear when the program on the computer had gone into an infinite loop!

  During the time I helped manage the PDP something new entered the world. An outside company, Apple, made a new kind of computer, the Macintosh. It was supposed to be handled by a pointing device. How odd! No commands and no prompt! And the cost for such a thing. The decision to acquire the Macintosh was taken by the company board.
  But it was possible to get around with such a machine. Quite good, after some time.

  A colleague of mine had some other news channel. On it he found out that there´s an alternative to the Macintosh. Something that a company called IBM had begun to market. It was called a Personal Computer. So it was to make a new approach to the company board about acquiring another kind of gadget. It became a little harder this time, as they had already approved that other toy computer. But when they were told that the new one had a prompt and you were supposed to give commands to it, then someone did lower the hammer.
  I was fascinated with the Macintosh, so it took some time to learn the needed commands to maneuver the new box.

  As time passes I´ve seen some other computers. One of the more interesting ones, was the System 10. No, not the Singer System 10 but the Digital System 10. It was powerful and you could do a lot of interesting things on it.
  I once knew two chaps that each had their own DEC System. One had a System 10 and the other a System 20. The one with the System 20 had the computer in his apartment. No, I was never invited there. There was no space to visit that chap. But it was cost effective to have it in the apartment. The electricity was included in the monthly rent!
