Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Hardware is CC ShareAlike 4.0 license, software is MIT license, nice! Great work! UPDATE: Code for boards is on GitLab: 6502, Z80, 6809 – Erturk Kocalar’s main GitLab here. Perhaps a Grand Central can approach original processor speeds? We’d like to see! Adafruit Grand Central specs: Cortex M4 core running at 120 MHz, 32 bit, Floating point & Cortex M4 DSP instructions, 1MB flash, 256 KB RAM.Arduino Mega 2560 specs: ATmega2560 at 16 MHz, 8 bit, 248K flash, 8KB RAM.Read more in the Hackster.io article here.Īdafruit note: this looks like an excellent project to try the Adafruit Grand Central board ( with and without headers):

With an Arduino Mega, the emulated RAM runs out quickly on more but the basic assembly program.įind more information on the RetroShield over on 8 Bit Force’s Tindie store. The RetroShield is developed by Erturk Kocalar of 8 Bit Force and sells for $18 (unassembled.) The kit includes a daughtercard, a socket, header pins, and an LED along with a 6502, Z80, or 6809. Instead, think of this platform as “wire-wrapping in software.” With this combination, it is possible to emulate vintage computers such as the Apple I or Commodore 64.Įmulated clock speeds are well below the original ~1 MHz with a Mega. It also provides a terminal connection back to the host PC. The Arduino Mega emulates the RAM, ROM, and I/O devices. Available daughtercards can socket 8-bit microprocessors such as the 6502, Z80, or 6809. Via hackster.io, the RetroShield emulates classic 8-bit computers when attached to an Arduino Mega compatible.
