I still have some expansion boards for Apple-1 available, they're test production leftovers.
- Wi-Fi Modem (https://p-l4b.github.io/wifi/)
- microSD Storage Card (https://p-l4b.github.io/sdcard/)
- Serial Interface ADD-ON for Commodore Disk Drives (https://p-l4b.github.io/iec/ - needs also microSD Storage Card)
Feel free to send me an email (or PM me here) if you're interested.
Thank you,
Claudio - P-LAB
Top notch cards, and a must own for every apple-1 or replica-1 builder!
