+ * the transporter) have a much higher probability of being
+ * damaged."
+ *
+ * This is one place where OPTION_PLAIN does not restore the
+ * original behavior, which was equiprobable damage across
+ * all devices. If we wanted that, we'd return NDEVICES*Rand()
+ * and have done with it. Also, in the original game, DNAVYS
+ * and DCOMPTR were the same device.
+ *
+ * Instead, we use a table of weights similar to the one from BSD Trek.
+ * BSD doesn't have the shuttle, shield controller, death ray, or probes.
+ * We don't have a cloaking device. The shuttle got the allocation
