Thank you Yoni. Your photos are good, but it would be even nicer to see pictures of the setup from an angle where one can see *exactly* how the wires are connected. If I manage to unbrick my computers I will try to take some photos myself. Also, your setup is for a SOIC-16 whereas mine is for SOIC-8.
I did get a bit further after mtjm explained to me in #libreboot that the table... 18 - - 1 22 - - NC NC - - 21 3.3V (PSU) - - 17 ...actually represents the pomona clip. I didn't see it because I got confused by the dashes. Previously I thought that the dashes were arrows and that 18 something should be connected to 1 something. I will make a new attempt tomorrow.
