ITXPlus: A Mini-ITX Macintosh Plus Clone
2025-05-21
ITXPlus is a Mini-ITX sized Macintosh Plus logic board clone built entirely from modern components. It uses a Pico-based VGA converter, a standard 24-pin ATX power supply, an onboard 50-pin internal SCSI header, and 4MB of soldered RAM. Leveraging open-source solutions like DosFox's sound chip replacement and an ATTiny-based RTC, ITXPlus aims for a fully functional, build-it-yourself experience. While floppy drive support isn't included by default, an expansion header allows for the addition of a real IWM. The board is almost entirely surface mount, using a traditional 68000 for easier assembly. The complete design will be open-source on GitHub.
