- a shift character code (▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄) switches between letters and numbers and punctuation
- 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
- each transmission blocks are separated by two shift characters
- numbers 1-5 is 1 to 5 dots, while 6 to 9 is one dash and 1 to 4 dots. zero is two dashes
- 1 ▄▄, 2 ▄▄▄▄, 3 ▄▄▄▄▄▄, 4 ▄▄▄▄▄▄▄▄, 5 ▄▄▄▄▄▄▄▄▄▄, 6 ▄▄▄▄▄▄, 7 ▄▄▄▄▄▄▄▄, 8 ▄▄▄▄▄▄▄▄▄▄, 9 ▄▄▄▄▄▄▄▄▄▄▄▄, 0 ▄▄▄▄▄▄▄▄
- punctuations: PERIOD/BREAK ▄▄▄▄▄▄, COMMA ▄▄▄▄, QUESTION MARK ▄▄▄▄▄▄▄▄▄▄, EXCLAMATION MARK ▄▄▄▄▄▄▄▄▄▄
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
