It's been up way before 91. I was surprised when that it actually turned when I 1st tried it. I had to get a new rotor box. (?) , hooked it up and voila it rotated. But a few years ago, it stopped. So I figured whatever positioned it stopped in, that's what I would get........ I do check the TVFool report and have a tough time deciphering what I should and shouldn't get. But now that I know 8 is pretty much out of the question . I'll check it out some more. Thanks so much Iceberg!! You are always so helpful!!!
