Designed within the Seventies by electrical engineer Chuck Peddle and his group for MOS Technology, the 8-bit MOS 6502 ran at 1-2 MHz and packed 3,510 transistors. As probably the most inexpensive chip of its form, it initially price lower than a sixth of the options supplied by Motorola and Intel.
The group that designed the MOS 6502 had beforehand labored at Motorola on the Motorola 6800 undertaking, so the 6502 is taken into account a simplified, sooner and cheaper model of that design. To put that in higher context, the 6502 was promoting for roughly $25 per chip, whereas Intel’s 8080 and Motorola’s 6800 had been each promoting for round $200.
By the Eighties, variants of the MOS 6502 had been powering a number of consoles and computer systems just like the Atari 2600, Apple II, Commodore PET, and naturally, the Nintendo Entertainment System (NES).
The authentic NES was powered by a customized MOS 6502, which was offered because the Ricoh 2A03 and manufactured by Japanese imaging and electronics firm Ricoh, who bought its begin in optical tools again within the ’30s and helped popularize cameras with its Ricohflex III in 1950. The Ricoh chip additionally included a 5-voice Programmable Sound Generator, plus different I/O interfaces.
