Behind Digitalisation there is the idea to have more control and the idea to create reality by own rules. Everything should become a rule. It is the opposite of analoge materials or analoge things are a subset of cyberspace. 
https://vintagecomputing.ch/?browseid=8893
digitalization was after the end of the idea of the replica of man as a robot and thinking being. something that the analog first read largely unchallenged. it was a colonization of a new space, a space that created itself - cyberspace. with this, this space did not come into conflict in a first moment - in the sense of earlier struggles over existing mostly analog territory. this is probably also one of the reasons why digitalization proceeded creepingly and was not perceived or actively fought by parts of the broad population (the nerds etc.). and many waves of digitalization then also emerged in the field of music (synthies) or games, for example, and took hold in everyday life at home. the normal things, however, continued to run until they then also arrived in the working environment.

Giger was an educated as an industrial designer. Afterwards he made art and after working with jodorowski on dune, he joined the aliens-team. He created the slick fast monster in ALIEN. he influenced with his style (developped before in paintings and sculptures) the whole scifi. And so he became also one of the most influencing artist for games like r-type and and and and and …

Amicom
Coder.
Amicom joined SPREADPOINT in 1989 together with Depeche. He was active as coder of very different things from MMU tools to demos. What he liked best was to explore and develop new programming tricks that could be used in demos and other places.

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

Tapes

https://vintagecomputing.ch/?browseid=1435
Tapes comes from the mainframe tapes and were popularised by music too. so often people used normal tapes-drives and for a zx81-games - there were even description how you had to connect the microphone-cable to the head-phone-jack and reverse. While loadibg a zx-81 game you hear the whole time the data coming in! so meta: sound was for people and maschines.analog digital. So there was no difference between an accoustic coppler and data from the tape.

Tiling was a design pattern often used in the beginning of the gamedesign.
Reason:
  • Tilebase is simple to use. Create the tiles and just say here is TileA, titleB.
  • Tilebase save space (######) - important in the beginning
  • Tilebased could be used for creating games (Labyrinths) with Sprites in front
  • You can create very fast new levels
  • The hardware has often tilebased background support 
  • Seamless tiles create very fast interesting backgrounds and foregrounds …

Areas like the demoscene or electronic games existed only rudimentarily as analog systems (pinball etc) In this sense they were new and updated the system.
Other areas changed or replaced existing areas: 
- Data collection and analysis (punch cards, etc.)
- word processing

First developing on Atari ST (Assembler) but never published something except a demo for a bbs 1993 (First founded by two brothers). First not released ‘product’. A listing game for Happy Computer. 
Than switched to Macintosh (1995 ). Games in C . And than published over the net (website) or in Maganzines Disc-Magazines as Shareware. Paid first with checkes (almost impossible to get the money for 15$ games), so switched to real money and than to KAGI.com a first worldwide payment service.
Inbetween the author worked produced Flash-Games for advertising and ported a lot of games for Java (Applets) 1996 . 
Afterwards switched to Objective-C on MacOSX with a new name: la1n.ch.

Floppy disc or magnetic disc are faster and mor flexible than tapes. you can load and store autonom (no start and stop) and not linear, you can store them here or there. but of course also expensiver (you cant anymore use a (music) tapedrive.
