About the Retro stack debug arduino mega shield

Retro stack debug arduino mega shield is an open source PCB design by gcoonrod, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 90.2 × 53.3 mm, with 9 components from 8 distinct parts.

By type, the board carries 8 connectors and 1 jumper.

It belongs with the retro computing and dev boards & breakouts designs in this gallery.

From the project

A retro computer project based on stackable PCB boards.

This Arduino Mega shield is designed to easily connect to the RetroStack Debug board via a 40 pin IDC connector.

- 6502 Bus is backwards. Pin 1 should be RESB but is VPB instead. - PHI2 should be connected to one of the digital pins that support interrupts (2, 3, etc) - Consider adding jumpers to send a few signals to interrupt pins. - Power seems to be leaking between the arduino and the RetroStack. Needs diodes?
