Simple homebrew 6502 computer

Sven Krasser blogged about his 6502-based homebrew 8-bit computer build: After completing my VGA Generator project a while back, I’ve embarked on a new electronics project: building a simple 6502-based homebrew 8-bit computer on a breadboard. There are a bunch of similar projects online from which to draw ideas. Some projects set constraints such as only […]

Vulcan-74: A 6502 Retro MegaProject

Radical Brad over at the 6502.org forum has been working on this cool 7400 logic VGA video game system, Vulcan-74: The Goals… Video must be perfectly stable VGA, putting out 256 colors at a resolution of 400×300 using an 8 bit color space divided into RRR-GGG-BB Video must include full 256 color 400×300 bitmapped screens with a […]

MEEPROMMER: (E)EPROM programmer based on Arduino hardware

mkeller0815 built  his own programmer – the MEEPROMMER, that is available at github: The idea behind this EEPROM programmer was to have a tool to get data on a 28Cxxx EEPROM for my own 6502 based computer. There are a lot of professional programmers you can buy, but for a lot of money. Using cheap […]

DIY 6502 computer using block transfer engine

Andre Fachat has written a post on his 6502.org blog detailing his DIY 6502 computer build. “I have built a DIY 6502 computer, which is mostly TTL logic only except for 65xx chips and ROMs, but the most TTL-ish part is the blitter: A block transfer engine that DMAs memory area from one location to […]

PROP-6502 Propeller laptop

Dennis Ferron developed this Parallax Propeller Laptop with a 6502 co-processor and 64K of static RAM as his entry to a Parallax Propeller design contest. He observed that hardware prototyping has evolved from building-block hardware (TTL) to programmable hardware (PLA’s and FPGA’s). He believes that the Propeller chip represents the next revolution: 100% software-based virtual […]

6502 microprocessor documentary in the works

“THE 6502” is a documentary series by Jason Scott about the MOS Technology 6502 chip, the circumstances that lead to it and the experiences of assembly language programming. Funded in 2011, the project is expected to go for several years of production, interviewing dozens of figures related to this subject. Those familiar with machine language, […]

27C3: Reverse engineering the MOS 6502

The MOS 6502 CPU, which was designed in 1975 and powered systems like the Apple II, the Atari 2600, the Nintendo NES and the Commodore 64 for two decades, has always been subject to intense reverse engineering of its inner workings. This talk by Michael Steil presents the way from a chip package to a […]
