Maybe changing the plan all together might be better, turn the computer center into a private enterprise. By now you know who the honest people are, recruit someone who you think can make a go of the center for a profit, let them have the computers so they can sell time on them and most importantly keep them running. I suspect that the elders will make a hash of running a computer center anyway-too much out of their area of experience. This might be an area where the market might be the best way to go, consider the computers seed money and call it an investment.
