So 49 man years/day would become 49*40 = 1960 man years/day. You have to write test procedures, develop test equipment, interrupt running factories, run tests, find lost source code, revise or rewrite the code, look for new ROMS, PROMS, EPROMS, EEPROMS to program, do the repair task, re-test at a system level. Lot's of work. A man week average might be low. Fred Swirbul can probably give us figures for nuclear reactors that we can extrapolate from. So if we put about half a million people on it we could do it in a year and we have more than a year. I wonder how many EEs and technicians exist world wide? We do seem to have a problem that will stress available resources world wide. Harlan
