For the purposes of this challenge, you wont need to worry about cycle timing if you dont want. The 6502 is one of the easiest real-world processors to emulate. Resources are linked at the bottom of this. This involves, of course, understanding its instruction set and its encoding format. ( October 2021)The challenge is to write your own 6502 CPU emulator. Further details may exist on the talk page.

He was so inspired that he immediately set to work on what would become the Apple I computer. Introductory advertisement for the Apple I computerOn March 5, 1975, Steve Wozniak attended the first meeting of the Homebrew Computer Club in Gordon French's garage. Actual chip designs, or run in a simulator (in effect doing what this program does).Production was discontinued on September 30, 1977, after the Jintroduction of its successor, the Apple II, which Byte magazine referred to as part of the '1977 Trinity' of personal computing (along with the PET 2001 from Commodore Business Machines and the TRS-80 Model I from Tandy Corporation). 6502 simulated at the transistor level, in Python or Javascript.

The Apple I went on sale in July 1976 at a price of US$666.66, because Wozniak 'liked repeating digits' and because of a one-third markup on the $500 wholesale price. To fulfill the $25,000 order, they obtained $20,000 in parts at 30 days net and delivered the finished product in 10 days. Very soon after, Steve Jobs arranged to sell 'something like 50' completely-built computers to the Byte Shop (a computer store in Mountain View, California) at $500 each. To fund this small venture—their first company—Jobs sold his van and Wozniak sold his HP-65 calculator. Wozniak calculated that having the board design laid out would cost $1,000 and manufacturing would cost another $20 per board he hoped to recoup his costs if 50 people bought the boards for $40 each. Then, Steve Jobs suggested that they design and sell a single etched and silkscreened circuit board—just the bare board, with no electronic parts—that people could use to build the computers.

The Apple 1 did not come with a case. All one needed was a keyboard and a television set. The Apple I's built-in computer terminal circuitry was distinctive. About 200 units were produced, and all but 25 were sold within nine or ten months.

It continued to be sold through August 1977, despite the introduction of the Apple II in April 1977, which began shipping in June of that year. In April 1977, the price was dropped to $475. This made the Apple I an innovative machine for its day. Competing machines such as the Altair 8800 generally were programmed with front-mounted toggle switches and used indicator lights (red LEDs, most commonly) for output, and had to be extended with separate hardware to allow connection to a computer terminal or a teletypewriter machine.

A unit was sold in September 2009 for $17,480 on eBay. In 2008, the website Vintage Computing and Gaming reported that Apple I owner Rick Conte was looking to sell his unit and was 'expecting a price in excess of $15,000 U.S.' The site later reported Conte had donated the unit to the Maine Personal Computer Museum in 2009. An Apple I reportedly sold for US$50,000 at auction in 1999.

On June 15, 2012, a working Apple I was sold at auction by Sotheby's for a then-record $374,500, more than double the expected price. The computer was brought to Polytechnic University of Turin where it was fixed and used to run the BASIC programming language. The high price was likely due to the rare documents and packaging offered in the sale in addition to the computer, including the original packaging (with the return label showing Steve Jobs' parents' address, the original Apple Computer Inc 'headquarters' being their garage), a personally typed and signed letter from Jobs (answering technical questions about the computer), and the original invoice showing 'Steven' as the salesman. In November 2010, an Apple I sold for £133,250 ($210,000) at Christie's auction house in London.

Following the Christie's auction, the board was restored to working condition by computer historian Corey Cohen. Copson's board had previously been listed on eBay in December 2011, with a starting bid of $170,000 and failed to sell. In October 2012, a non-working Apple I from the estate of former Apple Computer employee Joe Copson was put up for auction by Christie's, but found no bidder who was willing to pay the starting price of US$80,000 (£50,000).

On June 24, 2013, an Apple I was listed by Christie's as part of a special online-only auction lot called 'First Bytes: Iconic Technology From the Twentieth Century.' Bidding ran through July 9, 2013. An old business transaction letter from Jobs also was included, as well as the original owner's manual. This particular unit has Wozniak's signature. Auction Team Breker said 'an unnamed Asian client' bought the Apple I. On May 25, 2013, a functioning 1976 model was sold for a then-record €516,000 (US$668,000) in Cologne. On November 24, 2012, a working Apple I was sold at auction by Auction Team Breker for €400,000 (US$515,000).

On May 30, 2015, a woman reportedly dropped off boxes of electronics for disposal at an electronics recycling center in the Silicon Valley of Northern California. The sale included a keyboard, custom case, original manual and a check labeled 'Purchased July 1976 from Steve Jobs in his parents' garage in Los Altos'. On December 13, 2014, a fully functioning, early Apple I was sold at auction for $365,000 by auction house Christie's. The auction was run by Bonhams.

The machine was described as, 'in near perfect condition.' The owner, Tom Romkey, '.only used the Apple-1 once or twice, and. On September 21, 2015, an Apple I bearing the Byte Shop number 01-0059 was listed by Bonhams Auctions as part of their 'History of Science and Technology' auction with a starting bid of US$300,000. It is the company's practice to give back 50% of the proceeds to the original owner when an item is sold, so they want to find the mystery donor.

On the 40th Anniversary of Apple Computers 2016 the Dellimore's working Apple-1 went on loan and on display in 'Artifact' at the V&A Museum in London, England. However, Glenn and Shannon Dellimore, the co-founders of GLAMGLOW, a beauty company which they sold to Estee Lauder Companies, bought it after the auction through Bonhams Auction house.
