Description: This started when one of my raspberry pi projects failed due to voltage drop on the USB power cable that I was using, so I set out with my power supply and DC Load to measure the voltage drop of various cables that I use in my lab.

The mighty Mightyframe! I've done a video on the miniframe, a 68010 based computer before. The Mightyframe is a much beefier system, featuring a 68020, ten serial ports (expandable to 40) and 4 RS-422 ports. It came with three heavy Maxtor 1140 hard drives, full height drives with 140MB of space each. The mightyframe runs a customer version of Unix System V called CTIX.
