Silicon die of the first 555 chip (1971) Die of a CMOS NXP ICM7555 chip. The timer IC was designed in 1971 by Hans Camenzind under contract to Signetics. [3] In 1968, he was hired by Signetics to develop a phase-locked loop (PLL) IC. He designed an oscillator for PLLs such that the frequency did not depend on the power supply voltage or ...

An example of use of the breadboard area is Tranter's automatic power-on-reset modification using a 555 timer chip. [10] As well as the Woz [d] monitor, the Replica 1 included (integer) Apple I BASIC in ROM to allow quick and easy programming. [8] Memory was provided by a 32K byte 62256 static RAM Chip. [8] [e]
