indirect open source vs direct open source
https://vintagecomputing.ch/?browseid=3755
GameArt like other digital media art is distinguished by a technologically induced ephemerality as well as by a decentralised and therefore difficult longterm availability. More complicating, GameArt differentiates even further and orientiates itself towards earlier lines of game culture like play in backyards, malls and high streets. There is a wide range for designing, playing, and experi- encing GameArt that expands all the way back to a mode of playful experience and action. How can this wide range and depth of themes, interactive playing time, and game mechanisms possibly be archived and made accessible?
Archiving for a society with an open end, in other words a „ludic“ society, has to be determined by an open possibility of observing artistic instruments being developed in order to expand it fur- ther or contextualize it in a new way. The suggestion is to try to build an open and playful archive that includes involved parties and works (from a „knocked down“ curbstone pixel to a player) as well as bystanders (spectators) in a comprehensive setting. While there seem to be long known instances of recipients through whom art works only have been able to unfold their meaning (in play), artists with their possible intentions and, finally, the functional systems of society like sci- ence have to be included first. These instances would only be the first traces and layers among many in an open archive. Subsequently a new „philosophy of archiving“ will be drafted that origi- nates in specific phenomenons and questions of GameArt.
These emerging levels and models describe diverse and partly disagreeing strategies of GameArt. The works span from the game as a medium of artistic discourse to the outright subver- sive criticism of a pronounced „ludic“ society. Therefore a „Mille-Plateaux“-archive is at the same time the base we are standing on and the future we are developing (as a tool).

This is a start to collect data from vintage computing in Switzerland. It is a bottom up approach to collect and organize data. It is also a research for how to collect and store data. 
The data/information can be stored as nodes. The nodes can be as a tree (hierachy) and/or rhizome. 
This data is open for everyone who wants to also add his/her/its own data. Just create content. We will than try to bring it in an order. 
 
Listing Cultures

The listing culture is a hybrid between gutenberg galaxis and software. Software was often distributed in the mainframe time as source code ( c ). each system had a different set of hardware, processor. c and co were the platform. You could compile it for your system. 

The listing culture brought source code to the magazines and could be published. first with basic and co for homecomputers, later with checksums, than basic with assembler inlines, than only shortcodes. 
of course by typing in you could learn how to code and solve problems.

Hah, I might not be the best to explain Amiga history, but I’ll do my best :) Fish disks were the main way to distribute public domain, open source, shareware etc. before the internet was wide-spread. People would send Fred Fish software, and he’d compile them into individual disks that people would copy. Magazines would have lots of companies that would allow you to order copies of these disks etc. He ended up creating over a 1000 disks this way. When cd-roms became a thing, you could order the whole collection on those. Those were strange times :)
Aminet was the most famous ftp-archive for amiga software. It was run by the same guy that made Brainfuck, Urban Müller. Rather than chronologically like fish disks, it was organized by topic, with readme’s for every file. You could upload to a staging area, and he’d put them in place. Much like fish disks, companies would print cd-roms with the latest from aminet for those not hooked up to the internets (or on 56k modems, which was most people).

Question: When this demo was created?

Facts

  • TTV1 was the first file-based Amiga virus
  • Its creation was a fun experiment. It was inspired by the boot block based SCA virus which had reached dubious fame due to its very successful spreading and the flaw of overwriting the boot block. Would it be possible to create a self spreading file, thus breaking out of the boot block dread?
  • Development took place between spring and fall 1988.
  • The early code name was HOUZ virus.
  • Thinking up the name we tried to find something that would sound mean and at the same time on the verge to ridiculous. The final name was inspired by a rap band called The Terrorists.
  • The virus does not harm the system. In fact, care was taken to avoid any even unintentional damage.
  • Identity of the authors was kept secret for 30 years. It was officially revealed on March 9, 2019 at the Demonights 008 event in Bern Switzerland
  • "The names have been changed to protect the innocent" shown in the message was inspired by the song Beat Dis by Bomb the Bass. They have sampled it from the Dragnet radio series.
  • The "BGS9" was in fact a clone. Its code is almost identical even including the resident name "TTV1". It got more reach and thus was regarded as the origin.

About the life of the beast

  1. TTV1 installs itself as a reset proof resident module (KickTag/ROMTag) named "TTV1"
  2. On reset the resident module (virus) is called
  3. Execution gets delayed in order to gain disk write access. Therefore Intuition's OpenWindow function is redirected.
  4. As soon as the AmigaDOS tries to open the CLI window the OpenWindow gets called the virus looks for the startup-sequence on the booted disk
  5. The virus is looking for the first command (A) in the startup-sequence
  6. File request windows (e.g. "Disk is write protected") are being temporarily disabled
  7. Virus renames A to $a0202020a02020a020a0a0. This is a combination of none breaking spaces and spaces. The idea is that the user will oversee this "invisible" file.
  8. Virus writes itself as an executable command with the name of A to the disk
  9. Eventually A gets loaded and executed with all its parameters by the virus
The next time the user will boot the disk the virus gets loaded into RAM and step 1 takes place. On reset the horizonal beam position gets evaluated. If the beam position is smaller than a certain number the screen turns black and a message in white letters appears.
Market WAR
2023-03-20 16:48:40
https://vintagecomputing.ch/?browseid=7642
The Tandy Color Computer was the runner up. The Apple II was the winner in the category of home computer over $500, which was the category the Commodore 64 was in when it was first released at the price of $595.
n the United States, the greatest competitors were the Atari 8-bit 400, the Atari 800, and the Apple II. The Atari 400 and 800 had been designed to accommodate previously stringent FCC emissions requirements and so were expensive to manufacture. Though similar in specifications, the C64 and Apple II represented differing design philosophies; as an open architecture system, upgrade capability for the Apple II was granted by internal expansion slots, whereas the C64's comparatively closed architecture had only a single external ROM cartridge port for bus expansion.
Aggressive pricing of the C64 is considered to have been a major catalyst in the video game crash of 1983.
The price war with Texas Instruments was seen as a personal battle for Commodore president Jack Tramiel.[25] Commodore dropped the C64's list price by $200 within two months of its release.[6] I
Meanwhile, TI lost money by selling the TI-99/4A for $99.[26] TI's subsequent demise in the home computer industry in October 1983 was seen as revenge for TI's tactics in the electronic calculator market in the mid-1970s, when Commodore was almost bankrupted by TI.[27]
Although many early C64 games were inferior Atari 8-bit ports, by late 1983, the growing installed base caused developers to create new software with better graphics and sound.[34]

Subject:
'Re: VIC-II colors'
From: Robert 'Bob' Yannes
To: Philip
'Pepto' Timmermann
Date: 27.09.1999
I was involved with the development of the VIC-II, however the actual implementation of the design, including the Color
Palette, was done by someone else. I have forwarded your message to him, but it is up to him if he wants to respond.
I can tell you that the design was based on the principle that adding a sine wave of a particular frequency and amplitude
to an inverted version of the same sine wave at a different amplitude produces a phase-shifted sine wave of the same
frequency. The amount of phase shift is directly proportional to the amplitudes of the two sine waves.
The VIC-II used the 14.31818 MHz master clock input (4 times the NTSC color burst frequency of 3.579545 MHz) to produce
quadrature square-wave clocks. These clock signals were then integrated into triangle waves sing analog integrators. The
triangle waves were then integrated again into sine waves (actually rounded triangle waves, but good enough for this
application). This produced a 3.579545 MHz sine wave,
inverse sine wave, cosine wave and inverse cosine wave.
An analog summer was used to create the phase-shifts in the Chroma signal by adding together the appropiate two waveforms
at the appropiate amplitudes. The Color Palette data went to a look-up table that specified the amplitude of the waves by
selecting different resistors in the gain path of the summer. The end result was that we could create any hue we wanted by
looking at the NTSC color wheel to determine the phase-shift and then picking the appropiate resistor values to produce
that phase-shift.
Color Saturation was controlled by scaling the gain of the summer. When we picked the resistor values to determine the
output phase-shift, we also scaled them to produce the desired output amplitude. Luminance was controlled using a simple
voltage divider which switched different pull-down resistors into the open-drain output. We could create any Luminance we
wanted by choosing the desired resistor value.
I'm afraid that not nearly as much effort went into the color selection as you think. Since we had total control over hue,
saturation and luminance, we picked colors that we liked. In order to save space on the chip, though, many of the colors
were simply the opposite side of the color wheel from ones that we picked. This allowed us to reuse the existing resistor
values,
rather than having a completely unique set for each color
I believe that Commodore actually got a patent on this technique. It was certainly superior to the Apple or Atari approach
at the time, as they ended up with whatever colors that came out--ours allowed the designer to freely select Hue,
Saturation and Luminance.
Since all of this was based on selecting different resistor values and resistance varied from chip lot to chip lot, there
was variation from one Commodore 64 to another. It wasn't as bad as it could have been though, since all of the Chrominance
selection was based on resistor ratios, which could be kept constant even if the actual resistor values varied. Luminance
was more of a problem. A trimmer resistor should really have been used to pull up the output. This would have allowed the
Luminance to be adjusted for consistency from unit to unit, however Commodore didn't care enough about consistency to
bother with adjusting each unit

Games waren am Anfang einfach kopierbar. Ein Kopierschutz existierte nicht. Die Games wurden dann auch kopiert, was das Zeug hielt. Die Schweiz war prädestiniert dafür, denn sie kannte kein (digitales) Copyright – die Privatkopie lässt grüssen! Damit war das Feld weit offen für alle. Berüchtigt und bekannt waren die sogenannten Kopier-Parties. Häufig waren sie ein Missbrauch der Treffen in den Computerclubs. Erst mit der Zeit entstanden komplexere Schutzmechanismen wie nicht kopierbare Anleitungen oder Disketten mit Löchern. Diese ließen sich nun nicht mehr so einfach umgehen – und so entstand eine Szene von «Crackers».
Abbildung 11: Rudolf Stramm alias Hcc prüft den Code des Spiels WAR HELI und zeigt, wie gut der Kopierschutz eingebettet wurde. So gut, dass das Spiel nicht kopiert werden konnte, in der Konsequenz aber gerade deswegen auch keine sehr grosse Verbreitung fand. Screenshot aus de SRF Doku (Schlumpf/Trinkler 1989).
Crackers dis-assemblierten den Code und hatten damit den unkommentierten Source-Code vorliegen. Nach und nach entfernten sie die Schutzmassnahmen und gaben die Software frei. Meist handelte es sich dabei um Games.
Das Cracking war für viele selbst eine Art Spiel mit einer Spielmechanik. Rudolf Stramm alias Hcc beschrieb es als ein Duell zwischen dem Entwickler und dem Cracker:
“Man misst sich mit dem, der den Schutz gemacht hat. Es ist im Prinzip ein Wettkampf. Darum strahlt es einen gewissen Reiz aus. Es ist eine Sucht”.
Hcc, Rudolf Stramm, Min 15:09, in: (Schlumpf/Trinkler 1989)
Im besten aller Fälle integrierten die Cracker auch noch einen sogenannten Trainer. Damit konnte man sich eine unendliche Anzahl Leben geben oder sich an bestimmte Orte im Spiel teleportieren. Viele Spiele waren mit ihrem hohen Schwierigkeitsgrad nur so wirklich spielbar – so zum Beispiel das berüchtigte Rick Dangerous.
Der Name der Swiss Cracking Association singt im Namen von dem allem ein Lied. Und sie betätigten sich auch im ‘Schweizerischen GameDesign’. So crackten sie die Summer Games (C64, 1984) und ersetzten eine der Flaggen mit der schweizerischen Flagge und fügten dazu noch eine instrumentale 8 Bit Version der Nationalhymne ein. Wer auf die Schweizer Flagge klickt, hört diese Hymne. Das ist gleichzeitig Schweizer Game Design als auch die inoffizielle Hymne für das Schweizer Game Design.
Abbildung 12: Summer Games für den C64 (1984). Mit der Schweizer Flagge und Hymne gecrackt von der Swiss Crackers Association SCA.
Cracken bedeutete letztlich, eine Software und damit Spiele verstehen zu lernen. Und langsam aber kontinuierlich begannen diese Cracking-Gruppen die Programmierung von Spielen zu verstehen. Angefangen hat das bei der Darstellung von Grafiken und dem Abspielen von Musik, dann ging es weiter zur Integration von Spielmechanik – alles war erkennbar und letztlich auch wiederum einsetzbar. Wurden Grafik und Musik anfangs aus den Games extrahiert, kamen je länger desto öfter eigene Grafiken und eigene Musik hinzu. Unter den Mitgliedern von Cracker Gruppen entdeckt man viele spätere Grafiker und Musiker. Cracken von Spielen und Entwicklung eigener Spiele diente also durchaus auch als Startbrett für eine Karriere im Bereich der sogenannten Kreativwirtschaft sowie der IT.

la1n was the direct next step from imp89. New maschines and a new platform macosx. “Therefore i learned objective-c and coded real object orientated” and switched now to 3d games with opengl. The games were now more an more like gameengines and were object-orientated. But still hardcore coded. This change with the upcoming game engine like torque or unity. 
Therefore the last games from la1n.ch till now were again hardcore coded games like axe (atari 2600 vcs), vecZ (vectrex 2016).

Die Digitalisierung ist ein schwieriger Transformationsprozess, der seit 40 Jahren andauert und gegen den sich grosse Teile der Gesellschaft lange Jahre (zum Teil zu Recht) gewehrt haben. Letztlich geht es um die tiefgreifende Ablösung der auf Menschen-prozessierten-Medien zu auf Computern-prozessierten-Medien, die dann wiederum vom Menschen bedient, genutzt werden. Und selbstverständlich viele neue Anwendungen möglich machen. Die Corona-Pandemie hat nun die letzten Zweifler* zumindest zu Nutzern* gemacht.
Vom Auf-Menschen zu auf Computer-Laufende-Medien
Die Digitalisierung ist letztlich die Digitalisierung des Menschen zur Turing Maschine / Universalmaschine, einem einfachen Buchhalter mit Stift und Papier. Es ist die Kybernetik der 30 Jahre in der Realität, unserer Realität. Es geht um automatisch prozessierte Regelsysteme, die das erst möglich machen. Die Ausstellung zeigt in ihrem Ausgestellten ethnologisch und ethnografisch, was die Digitalisierung so erfolgreich gemacht hat, die Technologie dahinter ist anscheinend verschwunden. Sie ist im Hintergrund, im Handy, im Server (Server?) und ist damit handhabbar geworden. Nun ist sie durchsetzbar, weil sie niedlich und nett ist, was sie nie war. Die Digitalisierung wird zum Oberflächenphänomen und eine Ausstellung zum digitalen Planet schafft es, daran kleben zu bleiben. Ihr fehlt das digitale Herz! Sie ist letztlich nur GUI (Was die Computertechnologie ab 1985 sehr erfolgreich machte und mit dem WWW explodieren liess).
Diese digitale Welt ist nur möglich, weil millionenfach Programme warten, endlos warten auf Eingaben oder weil sie endlos vor sich hinrechnen. Selbst ein banales Programm wie Excel wartet bis der da draussen – genannte – User* etwas tut. Computer, Computerprogramme sind unsere kleinen je eigenen Sklaven, Maschinchen mit weissen Handschuhen.
