When was the MOS Technology 6502 processor made?
A MOS Technology 6502 processor in a DIP-40 plastic package. The four-digit date code indicates it was made in the 45th week (November) of 1985. Max. CPU clock rate
When did the Motorola 6502 microprocessor come out?
The design team had formerly worked at Motorola on the Motorola 6800 project; the 6502 is essentially a simplified, less expensive and faster version of that design. When it was introduced in 1975, the 6502 was the least expensive microprocessor on the market by a considerable margin.
When did the Commodore 6502 first come out?
The 6502 was next used in the Commodore PET and the Apple II, both released in 1977. It was later used in the Atari 8-bit family and Acorn Atom home computers, the BBC Micro, Commodore VIC-20 and other designs both for home computers and business, such as Ohio Scientific and Oric.
When did the Motorola 6800 microprocessor come out?
Motorola started the 6800 microprocessor project in 1971 with Tom Bennett as the main architect. The chip layout began in late 1972, the first 6800 chips were fabricated in February 1974 and the full family was officially released in November 1974.
Where to buy a 6502 chip retrocomputing Stack Exchange?
Mouser UK has them: Western Design Center (WDC) Through Hole Microprocessors. Neither RS nor Farnell (CPC) stock the Western Design Centre microprocessors. The only 8-bit chip you can get from those UK suppliers is the Z80. Jameco (USA) have the W65C02S6TPG-14, plus a variety of used 6502s for less.
Where can I buy a Western Design Center 6502 chip?
Western Design Center (that first “W”) licenses the manufacture of the chip to various silicon foundries, which wholesale them to dealers you can buy from online. If you don’t use this recent product code, you’ll find lots of offers for old or NOS 6502 chips whose origins will be more “dicey” than buying a new chip from a local chip reseller.
Where is the best place to buy a 6502 chip?
Some have market places where people sell tested 6502s; these tend to be more reliable than eBay. If you feel lucky, there are many sellers on eBay and Aliexpress who peddle (ha!) 6502s, but these are often untested, relabeled and/or of dubious origin.
How many instructions can an 8051 run per second?
With a 12 MHz clock frequency, the 8051 could thus execute 1 million one-cycle instructions per second or 500,000 two-cycle instructions per second.
What kind of microprocessor is the Motorola 6502?
In its CMOS form (the 65C02, which was developed by the Western Design Center ), the 6502 family continues to be widely used in embedded systems, with estimated production volumes in the hundreds of millions. The 6502 was designed by many of the same engineers that had designed the Motorola 6800 microprocessor family.
