  • CPLD 6502

  • This project implements an NMOS 6502 (with a few 65C02 extensions) in a set of 4 Xilinx XC9572XL CPLDs.
  • LEM6502

  • Well, maybe I should explain a little better. This idea came to my head after listening to an episode of the Retro Computing Roundtable podcast, If I recall correctly there was a discussion about powering an Apple ii (2) from lemon batteries.A ridiculous...
  • Fully manual PROM programmer

  • Detail As shown in the schematic, the address toggle switches, the data switches, and the LEDs are connected to the PROM device directly. Vpp +24V is supplied by DC/DC converter. Since the PGM signal need 50ms single pulse, a one-shot multi vibrator...
  • 6502 Graphing Calculator

  • OverviewThis is a graphing calculator based on a modern variant of the classic 6502 processor. Graphing calculators have been produced by companies like Texas Instruments that use classic processors like the Z80 and M68000 but never with a 6502. The...
  • Remoticon: PCB Reverse Engineering

  • Workshop Details: Ever needed the schematic for a PCB you didn’t design? Maybe you’re trying to repair it, modify it, or just understand how it works. However, you can’t find a service manual or even just a blurry photocopy of a schematic. In this workshop,...
  • FPGA VDP for BE6502

  • The main goal of this project is to add a video output to my 6502 homebrew computer. After following Ben Eater's video series on Youtube on how to make a 6502 computer on a breadboard, I felt like adding a more useful output than the 16x2 LCD.I played...
  • TG6502

  • TG6502 is a simple single board computer built around the 6502 CPU. It is still in development, but the ultimate goal is to have roughly the following features:32k of RAM128K of EEPROM, bank switchedRS-232 serial portVGA interfaceSome kind of keyboard...
  • 6502 breadboard computer

  • I have always been fascinated in how computers work so when I stumbled across Ben Eater's website I was blown away by how well he explains how to build an entire 8-bit computer on a breadboard. He also shows to build the 6502 breadboard computer and...
  • RetroShield for Arduino Mega

  • Specifications: Microprocessors supported: 6502, 6809, and Z80.Microprocessor clock runs at ~95kHz (based on Arduino code optimizations).Memory mapping and RAM/ROM/devices handled by Arduino code.RAM : 4~6 KB (using Arduino Mega’s 8KB RAM)ROM : 200+...
  • W6502SBC

  • An old topic has been bothering me for a long time. Assembler and 6502. My C64 has been mothballed for a long time, the VC20 is selling. Nevertheless, I find the 6502 very interesting in terms of assembly language. What you could do with 1MHz and 64kb...
  • JJ65C02

  • Intro I came across the various Ben Eaters 6502 Computer videos and addition to being impressed with his style, skill and knowledge, I also became intrigued. Back as an undergrad at JHU, one of my courses was in microprocessor architecture,...
