Building a Modular 6502 Computer | Ben Eater Inspired: Programmer Design Review

In-Circuit Programmer for 6502 Project - Theory of Operation & Schematic Review This video covers the design and operation of an in-circuit EEPROM programmer built specifically for the 6502 CPU board project. Learn how this programmer interfaces with the CPU board through a CPLD to enable on-board programming without removing chips. What's Covered: The programmer works in conjunction with the CPLD, which operates in three distinct modes: Mode 1 (Standard): CPU board functions as a normal computer Mode 2 (EEPROM Mode): 6502 placed in high-impedance state for programming Mode 3 (Hybrid/J-Link Mode): Real-time monitoring of address bus, data bus, and control lines during code execution Key Components: Microchip AVR64 DD32 microcontroller (24MHz, 64K flash, 8K RAM) FTDI USB-to-serial interface chip Line drivers and buffers for address bus control Desktop application for command-line control Technical Features: Command-line interpreter architecture USB communication via FTDI chip Address bus reading and writing capabilities Built-in LED logic analyzer for debugging TLA5202 logic analyzer support with synchronous clock output The programmer acts as a bridge between desktop software and the CPU board, executing commands to read, write, and erase EEPROM memory with built-in programming algorithms specific to the target device. Coming Soon: Separate videos on AVR64 DD32 programming and desktop software development. Github Link to project files: https://github.com/TerryAbs/ABSDataSystems
