I think daemon/demon came from printers demon, which is carved into the government printing office in Brisbane. the printers demon is the one which stuffed up letters in the tray, to make printers tear their hair out. Did I say tray? I meant case, upper case, the one above, with the big letters, and lower case, the case with the little letters. oh dear. really? is that why they are cases? data bus cables used to be the size of a moderate Dr Who Scarf, and just as colourful. Now we're all settled on terahertz speed 2 wire protocols or even one-wire, Its all a bit moot. At least we still talk about the backplane, but usually now, its connecting the edge of a CPU cluster, to the combination of power and a switch fabric. I dont think people assume a computer spans more than one card any more, unless its Intel struggling to fit the CPU on one chip, mounting two chips side by side and then spreading the power budget into two lines on the bus. Oh dear.. I got given the last generation PDP-11 on a chip, in a 72pin DIP. I gave it to somebody else who could use it. At the time, I thought it was Teh Awesome l33t to have an entire pdp11 on one chip. imagine! my god, the power, the power. I think the day is coming when a CPU has gold pins top and bottom. they have a very large number of pins. Somebody smart will have to invent code to work out how to wire the pins. Oh, hang on, thats why Djikstra's algorrithm which lies at the heart of routing protocols was written back in the day. oh dear.. its turtles all the way down isn't it?
