An 8-bit microprocessor developed by MOS Technology, introduced at a trade show in 1975 and in revised form still in contemporary production. In the mid to late 70s the processor sold for a mere $25 while Intel’s 8080 and Motorola’s 6800 cost nearly $200. As an example the popular successor still in use today is the 65C816. Another example the W65C02S6TPG-14 offers an extended set of instructions and a clock speed of up to 14 MHz (instead of the original 1 MHz).
Used most notably in:
