Boy this is not time-nuts and I had been deleting the thread. No problem with the thread. Just I have HP VNAs. Yes including what caught my eye the 8410 that Scott spoke of and its still operational. Heavy as heck like real equipment should be. I am curious I sort of thought the 8410 was pre micro processor and yet some how the HP85 hooked up to it??
I have the 8757 also so. Great comment by Dave on the fact that someone will give out some of the old options. Now I have to figure out what on earth that might actually mean.
