I've got 4 or 5 of these little boxes for 120v operation that hook in
series with a PC keyboard cable (5 pin DIN) and the mains supply for
the monitor (3 prong line cord; female IEC cord). They've got a 4-
position DIP switch on the back to vary the time between 10 and 40
mintues. The idea is that if the DIPswitch selected time goes by
without any keyboard inactivity will turn the monitor mains supply
off. Some are the "Monitor Miser" brand; others are the IBM Options
"Display Miser" brand--they're identical internally.
Free to anyone who wants the lot and pays postage.
Cheers,
Chuck
