You're an absolute legend!, I think it's time for me to order a Saturn for trimming.

Were there any odd issues or bugs you came across?

You actually did it you madlad! Thank you for your contribution! Do you have any other documentation you created along the way to get here, such as board scans or schematics? Would love to see how you got to this point, and see if others could use your notes to take it even further.
