The Illomi telegraph system used a pulse with modulated character code akin to [[W:Morse code|Morse code]], though the codes used are based upon letter frequency in [[Delang]]. The shift code ({{dash}}{{dash}}{{dash}}{{dash}}{{dash}}) had multiple functions. A single shift code switches between letters, and numbers and punctuation, while two starts and end a transmission blocks. Sending an unbroken series of 3 or 4 shift codes was used as an emergency code.

Pulse Width Modulation Code

The Illomi telegraph system used a pulse with modulated character code akin to Morse code, though the codes used are based upon letter frequency in Delang. The shift code (▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄) had multiple functions. A single shift code switches between letters, and numbers and punctuation, while two starts and end a transmission blocks.

After the radio telegraph became standard on ships and boats, two special codes was agreed upon, the emergency code (4 or 5 unbroken shift codes), and the attention code (3 unbroken Ҩ (AU) codes).

The Digital Revolution

The First Computers

  • electro-mechanical digital computers
  • wire based digital internal storage using PWMC
    • the digital storage was constructed using a mechanical telegraph key as output, a long coiled string, and a pickup transducer to pick up the signal
    • required a refresh circuit
  • no external digital storage

Second Generation Computers

  • mostly electronically digital computers
  • removable magnetic wire coil external storage using PWMC
    • wire coil strung from one spindel to another through a magnetic read/write head

Zero Deliminated Character Code

  • binary stream based digital storage
  • based upon Pulse Width Modulation Code
  • shift character codes switches between lower case, upper case, numbers, punctuation, and codes

Third Generation Computers

  • transistor based digital computers

Fourth Generation Computers

  • integrated circuit based digital computers

Fifth Generation Computers and Beyond

Stagnation and The Zeron
