I picked up an old Timex Sinclair 1000 computer from a thrift store recently. It came with a 16K RAM pack, but no power supply. The power jack looks like a 1/8" earphone jack and is marked "9V" -- but no polarity is indicated. I don't want to fry this thing, anyone know what the polarity is supposed to be on this thing? (I've done some web searches and not found the answer yet...)
