- ITXPlus is a Mini-ITX sized Macintosh Plus logicboard clone that requires no original parts.
- Features include onboard VGA output, 24pin ATX power supply, 50pin internal SCSI header, and 4MB of soldered RAM.
- Uses DosFox's Sony Sound IC replacement, SCHWIM IWM bypass, ATTiny-based RTC, and reverse-engineered Mac Plus PALs.
- Does not support floppy drives by default but includes an expansion header for IWM connection.
- Mostly surface mount design, except for the 68000 CPU and some connectors.
- Chose Macintosh Plus as the base for its ability to be built without original parts.
- Design will be open-sourced and posted to GitHub upon completion.
