The 10811 that I have has a decal on it that reads "upgraded to series
3010". Do you know what that means?

Lefty-

The 10811-60111 that came in my used HP 5334B counter, had a blown thermal
fuse. Upon considerable investigation, I found that it was a common problem
and had been addressed by HP, using fuse with a higher temperature rating. It
is possible that your 3010 refers to the thermal fuse upgrade.

Incidentally, the going price for a used 10811-60111 was around $100 a couple
of years ago. I trusted a guy and ended up with a second unit that also had a
blown thermal fuse!

Used equipment is NOT a "gray" market. Anyone who buys an
expensive piece of equipment is entitled to sell when they no
longer have a use for it.

In the very early days of newsgroups (musta been in the early late 1980's --
back when I had a Compuadd 286-25) there was a post put together from an HP
Engineer and an HP Sales Guy -- to the extent that you could order a tuna
sandwich, 8566A, but mayonaise OPT-010030 was an additional $0.30, if you
wanted the sandwich sliced, that was OPT-010031 for which you had to pay
$0.05. Of course, you could have the sandwich diagonally sliced, and on and
on.

If you filled out your registration cards you could get updates on the menu,
but once tuna fish sandwiches were discontinued spare parts could not be
reordered.

I was the project manager of the 5334B frequency counter.
It had an option to have a 10811 timebase. The standard
timebase, which I inherited from the 5334A design was
embarassingly bad, barely able to do 10 PPM. Unfortunately,
you cannot retrofit a 10811 to a 5334, because you need an
extra PC board. This board is required to be able to put
the 10811 on its side, because there isn't enough height for
it.

The gray market in used HP/Agilent test equipment is
really hurting Agilent in some products. My old division no
longer exists. I now work at Agilent Labs.
