 * TODO: Add smarter short detection? Automatically run an electrical test at
 *       startup and leave everything in input mode if shorts are detected?
 *       I'm especially thinking about the case of SIMM control pins shorted
 *       together, like CS and OE, which will default to opposite output values.
 *       Is this even worth implementing? It's probably only useful when testing
 *       newly-built SIMMs. We would need to implement a protocol for this so
 *       the programmer software can be alerted that a short was detected.
