I put together code a long (long) time ago and I forgot to post it. Perhaps somebody will find it helpful. I made this because I was using computers as redstone timers (for a reason I don't remember) and this code gave me a method of setting a timer up that continued to run after chunk loads/unloads.

The code basically allows you to set a computer to pulse a side at a specified interval, saves these values and loads them up on a reboot.

local tArgs = {...}
local program = shell.getRunningProgram()

os.setComputerLabel("pulser")

if fs.exists("pulseLog") then
  h = fs.open("pulseLog", "r")
  log = textutils.unserialize(h.readAll())
  h.close()
  sSide = log[1]
  duration = log[2]
  sInterval = tonumber(duration)/2
else
  if not tArgs[1] then
    print("Set parameters: <side> <pulse interval>")
    return
  end
  sSide = tArgs[1]
  duration = tArgs[2]
  sInterval = tonumber(duration)/2
  h = fs.open("pulseLog", "w")
  h.write(textutils.serialize(tArgs))
  h.close()
  h = fs.open("startup", "w")
  h.write("shell.run(\""..program.."\")")
  h.close()
end

while true do
  term.clear()
  term.setCursorPos(1,1)
  print("Pulsing "..sSide.." every "..duration.." seconds.")
  rs.setOutput(sSide, true)
  sleep(sInterval)
  rs.setOutput(sSide, false)
  sleep(sInterval)
end
