Post #587537

These RTL circuits that I use in the #MiniDragon continue to prove themselves indestructible. Just reversed polarity on the new decoder board on accident and the only thing that happened was the voltage sagged in that corner of the CPU and the power wires got real hot. Found the mistake, reversed the wires and it's running like nothing even happened. This is about the dozenth time I've done this. Not once has it damaged anything beyond once melting through a DuPont header that I just swapped out. They're also impervious to static. I've touched board headers and zapped myself real good multiple times, run power backwards to individual boards countless times, and wired things completely wrong. I've also dropped the hell out of them as well as over- and under-volted them while testing. They might be extremely obsolete designs that can't run fast compared to modern CMOS, but boy howdy are they more robust by a landslide.
