A-ONE Apple 1 replica family 2025
In 2025 Franz Achatz revived the A-ONE Apple 1 replica. The excellent design is refreshed, a new family member added: the A-ONE PLUS.
I now have the 2025 standard board, the 2025 PLUS and the 2006 EXTENDED. With the prototype boards with and without breadboard and the 2025 cassette interface.
Read all about the A-ONE here.
