Computer Evolution and Performance Part 10

DEC PDP-8

• Introductions 1964.
• Minicomputer first time (after the miniskirt).
• Does not require air-conditioned room.
• The form small, can be put on the table lab.
• The price is $ 16,000
• $ 100 + for the IBM 360
• Already there are applications & OEM.
• Bus architecture such as PDP-8 is later used by computers - the modern computer.
  

DEC - PDP-8 Bus Structure


Semiconductor memory

• Start the 1970.
• Fairchild.
• Size of a single core
• i.e. 1 bit of Magnetic core storage
• Holds 256 bits
• Non-destructive read
• Faster than much core
• Capacity approximately doubles each year
