FS/FT: Token ring UTP to Fiber media converters

I have 8 UTP (RJ45) to Fiber (ST connectors) Token ring media converters I'm looking to either trade for 8 10Base-T to 10Base-FL (ST connectors) or sell for what I've got in them. I bought them for $10.00/ea late last year them up for a local non-profit school, but all the gear I've set up there is Ethernet, so they certainly won't work for the intended application ;) These came without power supplies, but need 9VDC @ 1000ma to 1500ma. I tested one on a 1000ma supply, but I know some media converters used to use 1500ma supplies. I also have 8 9VDC 1000ma power supplies and the correct input connectors available for these units, but if there isn't any interest I'm going to see if I can get credit for them, as they cost me almost as much as the media converters. I put up a photo that I got from the original seller of these units here: http://www.techmonkeys.org/~tothwolf/classiccmp/foc3.jpg -Toth
