Well, Sandy the Soldering iron is officially retired. The tip breaking off also damaged some of the wiring, and the whole thing shorted out in a light show of sparks. Looks like I'll be getting a new one. It was about time the thing gave up, it lasted a good long while. Let us have a moment of silence for Sandy.

Some good news though: The boards for the game cartridges arrived today, a week sooner than expected. Once my new iron gets here, I'll order the rest of the parts and start testing the cartridges.
