R.I.P. Chuck Peddle
 

R.I.P. Chuck Peddle, absolute American engineering legend: Designer of MOS Tech 6502 microprocessor, designer of PET. Died Dec 15, 2019. His Legacy shall live on. His brilliance touched so many lives.

The 6502 powered so many 8-bit machines, and played 10s of 1000s of games.

From Wikipedia
Quote:

One of the first "public" uses for the design was the Apple I microcomputer, introduced in 1976. The 6502 was next used in the Commodore PET and the Apple II,[50] both released in 1977. It was later used in the Atari 8-bit family and Acorn Atom home computers, the BBC Micro,[50] Commodore VIC-20 and other designs both for home computers and business, such as Ohio Scientific and Oric. The 6510, a direct successor of the 6502 with a digital I/O port and a tri-state address bus, was the CPU utilized in the best-selling[51][52] Commodore 64 home computer. Commodore's floppy disk drive, the 1541, had a processor of its own—it too was a 6502.

Another important use of the 6500 family was in video games. The first to make use of the processor design was the Atari VCS, later renamed the Atari 2600. The VCS used an offshoot of the 6502 called the 6507, which had fewer pins and, as a result, could address only 8 KB of memory. Millions of the Atari consoles would be sold, each with a MOS processor. Another significant use was by the Nintendo Entertainment System and Famicom. The 6502 used in the NES was a second source version by Ricoh, a partial system-on-a-chip, that lacked the binary-coded decimal mode but added 22 memory-mapped registers and on-die hardware for sound generation, joypad reading, and sprite list DMA. Called 2A03 in NTSC consoles and 2A07 in PAL consoles (the difference being the memory divider ratio and a lookup table for audio sample rates), this processor was produced exclusively for Nintendo. The Atari Lynx used a 4 MHz version of the chip, the 65SC02.

Thanks for posting this. I honestly didn’t know if the man but I should have. That processor was pretty amazing for its time.

Some of my earliest programming was in 6502 assembly. God, 8 bit multiplication was a pain in the ass.

But the 6502 and 8086 chips ushered in the PC era. If there was a computer science hall of fame, Peddle would be one of the top stars.

Was the 68020 a offshoot of his chip? If so it powered many of Atari/Midway's arcade cabinets, including T-Mek, Rampart, Xybots, Toobin and Vindicators.

I am happy for this guy. He got to be involved in so many things which ushered in the computer age.

I hope he died satisfied knowing his life mattered.

No. The 68020 is a Motorola 32 bit chip.

Ahh thanks for clearing that up, in any case no one can deny his contribution to the industry. RIP Mr. Peddle.

This is the kind of post that keeps me coming back. Well done, thanks for this.

6502! The first RISC processor! :)
