Apple ii cassette adapter: common questions

What microcontroller does the Apple ii cassette adapter use?

The Apple ii cassette adapter is built around the Arduino_Nano_v2.x, from the AVR/Arduino family.

How big is the Apple ii cassette adapter PCB?

The Apple ii cassette adapter measures 103.9 × 87.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Apple ii cassette adapter?

22 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Apple ii cassette adapter design files?

From the erikarn/apple-ii-pcbs repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Apple ii cassette adapter design in my own project?

The repository has no license, so all rights stay with erikarn. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Apple ii cassette adapter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
