“The 6502 microprocessor first appeared in 1975 and was designed by a small team led by Chuck Peddle for MOS Technology. Back then it was used in video consoles and home computers including the Atari, Apple II, Nintendo Entertainment System, BBC Micro, Commodore VIC20 and 64. At that time it was one of the cheapest on the market. It has never really gone away and now it is used by hobbyists and professionals for many applications.
The version I am using is the W65C02S6TPG-14 which is made by Western Design Centre and uses ten times less power than the original. It is special in that it does not have to run at 1 MHz like the original chip. It can run much slower or be used to single step through a program and even ramped up to 14 MHz. The Data Sheet for the chip explains its capabilities. Other 6502 chips do not have this capability and will not run this way. The chips are currently available on Ebay as well as other sources.
