Hi, I just received a knockoff programmer and some SMD adaptor boards from eBay. So was able to solder one of my 24 cent processor chips to a 25 cent adaptor board and program it to run a blink test.

Fantastic, great you are up and running. That is good to know that SDCC can be installed with binaries provided on the main site. Thanks for the information on how to get the additional Go libraries.

That's funny. Normally the joke is the finals sacrificed themselves to protect the fuse. Maybe some thought could be given to this form of circuit protection. Maybe attach a spring to the transistors
