Dont' really want an old cable, would like a new cable, but to emulate the old look. The 500's seem to have a rubber cord, not cloth, which would make it super easy.

Next would be to get an RJ11 connector for me to crip a rounded line cord myself.. (I crimp ethernet RJ45's all day long, so RJ11 shouldn't be that hard..) Though I think I might give the phone cord a twisted pair wire, if it won't cause harm, to keep noise to a minimum..
