    Sure, I could try and do the same hard work that plenty people have done before me, do miserably and fail - or I could just try and get stuff from back then working. So within chip shortage I tried to get hold of the MSP chip that's featured on the GoodFET, a DIY JTAG and more probe, that isn't obtainable anywhere. Thankfully everything I needed was accessible and so I started redesigning the GoodFET in KiCad, swapped some parts and added rounded corners basically and ordered the boards at OSHpark. Why did I do that? Because all the tutorials from 2010 basically start with "connect your GoodFET to the im-me messenger" and well I need one then, of course.

If you get yours working, I'll bring mine to Congress and we can chat.  Or scan the lower bands.  Or...
