- * devices (such as the computer, which is in the core of the
- * ship and has considerable redundancy) almost never get
- * damaged, whereas devices which are exposed (such as the
- * warp engines) or which are particularly delicate (such as
- * 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
- * for the cloaking device, then we shaved a half-percent off
- * everything to have some weight to give DSHCTRL/DDRAY/DDSP.
