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. A shift code (▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄) switches between letters and numbers and punctuation, and each transmission blocks are separated by two shift characters.
- Ex: SHIFT SHIFT T H I S SPACE I S SPACE A SPACE T E S T SHIFT 1 2 3 SHIFT SHIFT

- Ex: SHIFT SHIFT T H I S SPACE I S SPACE A SPACE T E S T SHIFT 1 2 3 SHIFT SHIFT
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
