So this could give some choises when it comes time to do the standard engineering dill of allocating requiremnts to subsystems. First a couple side isues. Every PC I have seen, going back to the first IBM 8086 powered PC can be reset by shorting two pins on a standard 0.1 inch spaced header. Hardware that performs this function is one part of a larger system that needs to by planned out. The normal application is an ISP who has a remote office filled with Linux boxes that interface phone modem banks to a high speed trunk line.
Offices are scatterd around a city to provide local number toll free Internet access.
That is with no human operater physically present. At least not a full time operator. In some cases just a self in someones phone closet. Needless to say the continued operation of these machine is critical to the company's bussiness. Running one of these setups is not a whole lot diferent from running a remote TASS site.
