As you will have gathered from my posts on this mailing list, I bought
something from eBay that was supposed to be an HP 58503A:
But I have every reason to believe has a new case and serial number
label fitted to the old chassis. The serial number just fell off in
fact, but I managed to find it on the floor! I can't imagine HP serial
numbers falling off, but this one did!!
Does anyone know of a person that could give an expert opinion of the
unit, to ascertain whether it is a fake or not? Ideally someone who
worked at HP on these units.
If so, please drop me a private email.
