From the project

Vintage Verification: Gamma Spectroscopy with MOS 6502 and Apple IIe

IBX II is an information barrier setup for nuclear warhead verification with an Apple II (Details). This repository contains schematics and layout files for two custom Apple II peripheral cards.

The KiCad files use the [Apple \]\ Edge Connector Template, best place it inside the directory as (Apple2_Bus).
