The Z-80

Several Z-80s are seen here on a wafer, a chessboard-like slice of silicon that contains hundreds of chips. Wafers are cut up into separate ICs and place into individual packages, which are then plugged into circuit boards. The Z-80 can control up to 64K bytes of memory and add two 8-bit numbers in one millionth of a second; it multiplies by repeated addition. The purple color is the result of a bright light being shone onto the wafer. Actual size of the Z-80: 0.157 x 0.167 inches.
