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 shift code (▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄) had multiple functions. A single shift code switches between letters, and numbers and punctuation, while two starts and end a transmission block.

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). Both of these codes are still in active use as warning signals in local communities. While the emergency code is only used for serious emergencies, the attention code is often heard before a tropical storm, specially in the free floating local communities on Tejmokh.

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
