      6 programming was hard, programs were hard to change once written
      7 
      8 Computing sounds
      9 
     10 - used for work purposes:
     11     - old computers like ARRA were built with relays, so you could listen to its sounds to debug
     12     - sounds were used to announce termination, auditive monitoring, specific program navigation
     13     - ARRA II had transistors and was silent…so they added a speaker to still get those sounds
     14 - but unorthodox purposes too:
     15     - Strachey wrote code that could make EDSAC hum God Save The Queen
     16     - soon, computers were used to create music, like Jean Michel Jarre did
     17 
     18 Further appropriation was through simple games, like tic-tac-toe and nim
     19 
     20 The language and metaphors
     21 
     22 - around 1955, computers started appearing in movies/TV
     23 - the language changed over time
     24 - new verbs like “program/programming”, “plugging”, “assembling”, “memory"
     25 - computers were appropriated, people started using old words for concepts related to technology

     27 ## IBM “Big Blue” vs everyone else
     28 their tactic was FUD — you need to get this new thing rn

     30 IBM & the Seven Dwarves (US):
     31 
     32 - Burroughs
     33 - Sperry Rand (formerly Remington Rand)
     34 - Control Data Corporation
     35 - Honeywell
     36 - General Electric
     37 - RCA
     38 - NCR

     40 IBM & the European dwarves
     41 
     42 - Odhner, St Petersburg (1873), which was cloned everywhere after 1917
     43 - Atvidaberg Industrie, Sweden, produced Facit. Went bankrupt in 1970 and sold to Electrolux
     44 - Zuse, Germany. Z4 in 1949, Siemens AG in 1967
     45 - Mailufterl, Vienna, Austria, 1955.
     46 - Bull, France, office machinery in 1930, then Gamma 3 (1952), multipurpose Gamma 60 (1958), GE (1962), Honeywell (1968). Had support from the French government.
     47 - Electrologica, NL. Electrologica in 1956, X1 in 1959, X8 in 1964, bankruptcy in 1966.
     48 - Regnecentralen, Denmark, 1955. ICL (Intl Computers Limited) in 1989, as merger of 3 companies.

     50 Why didn’t they succeed? Compared to IBM, they couldn’t sustain the resources. Also, each government wanted to make their own computer, because nationalism is a thing that exists. The money was there because of the Marshall Plan in the US.
