An expandable SBC-version of the Apple 1 computer, easy to get started with and lot of cool stuff that can be added to it!

Simple board for adding composite video or S-Video to a Sega Master System II

Arduino Mega 2560 shield adding secondary 1802 processor to run the latest 1802-based software (most may be from the 70s).

Simple joystick tester, can be used with the common Atari 9-pin joysticks and paddles (tested using multimeter).

With the RC6502-project for making an Apple 1 replica done I wanted to do something different, so I started designing a simple version of the RCA 1802-based Cosmac ELF instead.
