Just thought I’d post this update.  I did a dry run to confirm that the Mac Mini 2018 CAN be ‘simply’ modified to run on a straight DC supply. By following my pinout diagram posted earlier, I was able to temporarily affix some jumpers to the appropriate header pins and clip lead those to the terminals of a SLA battery and the computer started up fine. No weird, multiple voltages required.

Incidentally…  I also tried a power supply I have laying around which is 100W @ 12VDC. As anticipated, the machine would not start from this supply as it is only capable off supplying ~8.3A. I imagine the battery is capable of 20A or more so it was the obvious choice for testing.

I will be carrying out the full mod in the coming days/weeks and will post again after completion.
