A 68000 socketed ITX form factor Minimig.
Tested by Zenon to boot with Pistorm and CaffeineOS, also with a regular M68k CPU. It appears to be fully working, however it still needs further testing to confirm complete functionality of all features. It also needs more general trace cleanup/enhancement. Build at your own risk.

At the time of making the cart, the headphone jack and PS/2 ports are out of stock. They are able to be sourced from Arrow and Digikey. This cart may have items go in and out of stock depending on global shortages and EOL products. I recommend using Octopart and other similar sites to search for parts. The main Xilinx FPGA can be purchased from UTsource for around $30 and they are a pretty reliable supplier. I caution using sources like Ebay and Aliexpress, especially from China-based sellers with little to no feedback since they'll often sell counterfeit items.
As a DIY project, total cost for all parts and a board should come out to just under $150. (plus the cost of a CPU/Pistorm, power supply, and case)
An interactive HTML BOM has been added to the main repository to assist with building.
v0.6 -- Current rev to build. Updated PS/2 Mouse & Keyboard to use redundant clock & data lines due to issues with some keyboards and mice using splitter style pinout.
v0.5 -- Updated silkscreen for capacitor polarity upon community request. Updated iBOM and BOM.
v0.4 -- Corrected PS/2 Mouse & Keyboard pwr/gnd pinout.
v0.3 -- Changed soft-power circuit from 555 timer to a MAX16054, cleaned up a few traces with lots of vias. Still need more cleanup. [depreciated rev, do not build]
v0.2 -- Initial rev with corrected 68k socket size. [depreciated rev, do not build]
v0.1 -- Alpha release, incorrect 68k footprint width. [depreciated, removed]
