It would by no means qualify under today's acceptance of the term computer, and is by no means a "system".

Why do you think you need to train the world when it is you that refused to get an upgrade? All the while, at the same time, claiming to have worked with the world's most renowned "bit gods". What happened to *you*?

Electronics inside the TV can detect these pulses and use them to trigger the beam's horizontal retrace. The actual signal for the line is a varying wave between 0.5 volts and 2.0 volts, with 0.5 volts representing black and 2 volts representing white. This signal drives the intensity circuit for the electron beam. In a black-and-white TV, this signal can consume about 3.5 megahertz (MHz) of bandwidth, while in a color set the limit is about 3.0 MHz. "A vertical-retrace pulse is similar to a horizontal- retrace pulse but is 400 to 500 microseconds long. The vertical-retrace pulse is serrated with horizontal- retrace pulses in order to keep the horizontal-retrace circuit in the TV synchronized." See the referred to figure on the web page. |
