README
README.mdapple2idiot card
A general purpose ESP32 Wifi and Bluetooth board for the Apple II family of
computers (with expansion slots).
This card is essentially an ESP32 module and a dual-port ram chip. The Apple computer and the ESP communicate via the dual-port ram. That means that the ESP32 doesn't acutally have access to read/write any of the Apple computer's data or address busses. I think that's ok. In fact, I think this card is so simple, and stupid, that lots of fun little things can be done with it, but it's not meant to "get your Apple on the internet".
As a user of the card, you write the software that runs on the ESP32 module,
and the software that runs on the Apple computer. In the examples/ folder
are examples of how to do simple little things. Software on the apple just
peeks/pokes commands and data to the ram chip, and the ESP responds however
it's programmed to resppond.
Some of the example programs that have been developed so far
- Send a message to Slack.
- Get current weather conditions for a city.
- Select Wifi AP.
- Dedicated rot13 string encoder.
Status
The Card
This is actively being developed (as of July 2022). The rev 0.2 boards have arrived, and they work as designed. The gerber files are here in the repo.
The Apple II Software
There are examples written in BASIC and in cc65 in the examples/ directory.
The Card Software/Firmware
The ESP32 can be programmed using whatever you want. For example, you can use the Arduino IDE/C++ or you can use Lua, or Espressif's environment. Example Arduino programs are in the repo under examples.
What could be done with an Apple2Idiot card?
Here are some things I'm interested in making work...
- Prodos clock driver (NTP -> ESP -> Prodos)
- Home automation using MQTT
- Peer-to-peer local area chat/games using ESPNOW or something similar
- Wikipedia access

Questions
How big is the Apple2idiot new PCB?
It measures 167.6 × 77.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Apple2idiot new use?
11 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Apple2idiot new KiCad files?
From the equant/apple2idiot repository on GitHub, at the commit this page was made from: the board is card/apple2idiot_new/apple2idiot_new.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Apple2idiot new design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
