Nice writeup!
Yeah, that font! :D
I didn't have a deadtest cart back in ancient times, but I built one when I built my first C64 (from PCB and up), and the first thing I did with that machine, was to boot it with the dead test cart.. Which didn't work because the PCB I got didn't wire the pins it needed.. I thought on it until I figured that hey! chip select pin!! And then I jumpered that pin and saw for the very first time, a brand new C64 come up and vomit garbage all over the screen because I had gotten a wrong chip! :D
