INTRODUCTION Many years ago, in 1976, MOS Technologies designed the KIM-1 microcomputer system to promote their 6502 CPU. This single-boad computer offered 2KB ROM, 1KB RAM, hex keypad, 7-segment LED display and little I/O (serial and tape interface). Let’s build a modern 6502 based single-boad computer with a more convenient user interface – the KIM-64.… Read more KIM-64
INTRODUCTION Matured computer hardware (e.g. Arcade PCBs, home computers, etc.) usually don’t have a debug interface, nor do they provide an easy way to alter the firmware. This firmware in form of an integrated circuit in a DIP-package ROM and/or EPROM is fitted on the PCB. This blog introduces a EPROM EMULATOR which can be… Read more EPROM EMULATOR SHIELD FOR ARDUINO MEGA 2560
