Apple2-Prototyping-Card is an open source PCB design by tebl, published on GitHub. It is a 2-layer board measuring 249.6 × 78.7 mm, with 99 components from 8 distinct parts.
It belongs with the retro computing designs in this gallery.
From the project
Prototyping card for developing new hardware for legacy Apple ][, //e and //gs computers.
Several versions of the prototyping boards are available that can be used with the Apple ], //e and //gs, with size and cost being the main difference between them at this point in time. The smaller one should fit within the cheapest option for most Chinese PCB fabrication services, and so would be the perfect place to start when experimenting with the easier stuff. The fullsize version should give all the space you need for most projects. For more general information, see the [main project page.
