ebay: Antique UNICAC computer memory planes

I have never ordered from the guy, because I smelled a skunk. The
only info I have came from his own ads and web pages; I have not
actually been "done wrong" by him. The pictures do look great,
and if everything looked consistent with that, I'd have probably
ordered one or two myself.

But here I'll quote from his web page, which lives
at http://www.netw.com/~drfcline/univac.htm :

The ellipses were just some happy talk about how cool cores and Univacs
were. I agree with him there, wholeheartedly. But those last two
sentences sounded to me as if there were no cores to be had. If he
had them for sale, how could be be calling them "long gone"?

Well, okay, we have at least one confirmed order in which cores are
really present, and nobody griping about getting ripped off. The
only sane conclusion is: you are right, I mis-read it in a big way.
Guess I'm so used to scams that I'm seeing them even when they are
not there.

Thanks for the correction! On top of setting me straight on something
that I felt bad about, this means maybe I can talk myself into (out of?)
ordering one! :-)

Apologies to Dr. Cline, and to the list, for my outburst.

        Bill.
