Alive Dead Media 2020: Tracker and Chip Music
Alive Dead Media 2020: Tracker and Chip Music 1st day introduction, Markku Reunanen Pics gracefully provided by Wikimedia Commons Arrangements See MyCourses for more details, but for now: ● Whoami, who’s here? ● Schedule of this week: history, MilkyTracker with Yzi, LSDJ with Miranda Kastemaa, holiday, final concert ● 80% attendance, two tunes for the final concert and a little jingle today ● Questions about the practicalities? History of Home Computer and Game Console Audio ● This is a vast subject: hundreds of different devices and chips starting from the late 1970s ● In the 1990s starts to become increasingly standardized (or boring, if you may :) so we’ll focus on earlier technology ● Not just hardware: how did you compose music with contemporary tools? ● Let’s hear a lot of examples – not using Zoom audio The Home Computer Boom ● At its peak in the 1980s, but started somewhat earlier with Apple II (1977), TRS-80 (1977) and Commodore PET (1977) ● Affordable microprocessors, such as Zilog Z80, MOS 6502 and the Motorola 6800 series ● In the 1980s the market grew rapidly with Commodore VIC-20 (1980) and C-64 (1982), Sinclair ZX Spectrum (1982), MSX compatibles (1983) … and many more! ● From enthusiast gadgets to game machines Enter the 16-bits ● Improving processors: Motorola 68000 series, Intel 8088/8086/80286 ● More colors, more speed, more memory, from tapes to floppies, mouse(!) ● Atari ST (1984), Commodore Amiga (1985), Apple Macintosh (1984) ● IBM PC and compatibles (1981) popular in the US, improving game capability Not Just Computers ● The same technology powered game consoles of the time ● Notable early ones: Fairchild Channel F (1976), Atari VCS aka. -

IEEE Spectrum: 25 Microchip
IEEE Spectrum: 25 Microchips That Shook the World http://www.spectrum.ieee.org/print/8747 Sponsored By Select Font Size: A A A 25 Microchips That Shook the World By Brian R. Santo This is part of IEEE Spectrum 's Special Report: 25 Microchips That Shook the World . In microchip design, as in life, small things sometimes add up to big things. Dream up a clever microcircuit, get it sculpted in a sliver of silicon, and your little creation may unleash a technological revolution. It happened with the Intel 8088 microprocessor. And the Mostek MK4096 4-kilobit DRAM. And the Texas Instruments TMS32010 digital signal processor. Among the many great chips that have emerged from fabs during the half-century reign of the integrated circuit, a small group stands out. Their designs proved so cutting-edge, so out of the box, so ahead of their time, that we are left groping for more technology clichés to describe them. Suffice it to say that they gave us the technology that made our brief, otherwise tedious existence in this universe worth living. We’ve compiled here a list of 25 ICs that we think deserve the best spot on the mantelpiece of the house that Jack Kilby and Robert Noyce built. Some have become enduring objects of worship among the chiperati: the Signetics 555 timer, for example. Others, such as the Fairchild 741 operational amplifier, became textbook design examples. Some, like Microchip Technology’s PIC microcontrollers, have sold billions, and are still doing so. A precious few, like Toshiba’s flash memory, created whole new markets. -

Chapter 3 Microprocessors in the 1970's The creation of the transistor in 1947 and the development of the integrated circuit in 1958/59, is the technology that formed the basis for the microprocessor. Initially the technology only enabled a restricted number of components on a single chip. However this changed significantly in the following years. The technology evolved from Small Scale Integration (SSI) in the early 1960's to Medium Scale Integration (MSI) with a few hundred components in the mid 1960's. By the late 1960's LSI (Large Scale Integration) chips with thousands of components had occurred. This rapid increase in the number of components in an integrated circuit led to what became known as Moore’s Law. The concept of this law was described by Gordon Moore in an article entitled “Cramming More Components Onto Integrated Circuits” in the April 1965 issue of Electronics magazine [338]. -

Oral History of Charles Ingerham “Chuck” Peddle Interviewed by: Douglas Fairbairn and Stephen Diamond Recorded: June 12, 2014 Mountain View, California CHM Reference number: X7180.2014 © 2014 Computer History Museum Oral History of Charles Ingerham “Chuck” Peddle Doug Fairbairn: OK. So it's June 12, 2014. We're here at the Computer History Museum. I'm Doug Fairbairn and we're talking with Chuck Peddle, who's the creator of a number of very important things in the microprocessor and personal computer and other things we'll be discussing as part of this oral history. So Chuck, we're delighted to have you here. And thank you for coming over and spending the time with us. Chuck Peddle: Yeah I'd like to go on record right now saying what you guys are doing-- the idea about getting all the old men to come over and talk-- is a great idea. I don't know who came up with it, but it really is something that needs to happen. And it's consistent with-- Fairbairn: Well thank you. Peddle: --it's consistent with what you're doing with the museum. But catching these guys while they're still alive-- I suspect you thought probably Jobs brought it home to you. Stephen Diamond: Well we actually didn't get Jobs in an oral history like this-- Peddle: That's what I'm saying. That's what I'm saying. Fairbairn: --but that's an example. Peddle: Yeah, I think that may have been one of the things that triggered you starting it.
