I wonder how many collector's item HP machines were destroyed to make
these works of art.

None.

From the constructor:
"The Lockheed F-104 Starfighter was the second of four I made more
than 30 years ago with defective and scrap HPchips. This aircraft
model I made with IC,s of the Clasic and Woodstock pocked calculator
series. This model has a modified HP-67 card reader mechanism built-in
that moves up and down the landing gear, pilots' cabin and the engine
light and four intermitent tricolor leds, powered by 6 V."

What a relief...

Those are recyclable packages, not scrap.

Thank goodness that no working HP calculators were injured during the making
of those models.

That gave me quite a scare. I had to go pull out my HP 9825T, 35, 67, 97,
34C, 38C, 42S, 12C, 16C, 32SII, 17BII+, 48SX, 48GX, 50G, 33S, 35S, and 20B
and give them all a hug.

Phew!

What? No HP11C? Still in (heavy) use here. The 12C is for finance guys
AFAIK. Probably a lot of those will show up on the 2nd hand markets
soon, along with their owners ...

Which part of the calculators were the plane wheels?

Hard to see. Maybe the coin cells, with some black rubber bands? The
first set of coin cells in my HP11C lasted around 15 years. Those old
engineers sure knew their stuff.

Ever driven by there? HUGE place!

No, but a pilot friend of mine told me about his experience at an
aircraft salvage yard farther west. He said it's not for the squeamish,
that there'd be lots of crash fuselages and they seem to not always
clean the cockpit after removing the bodies ...

HP12Cs are still being made, $70 retail, so I doubt they'd bring much
more than $100 on eBay... ;-)

An HP11C, OTOH, I might buy. I bought a 35S a year ago. Don't like
it as much as either my long stolen HP11C or weak in the keys 35
year-old HP45.

Yes, Costco even had them a while ago. Anniversary edition. Not exactly
the same electronically but it sure was a nice touch. I wish they'd also
do that with the HP11C. And yeah, when my wife absolutely wants me to
trudge along to a yard sale I always keep looking for those calculators.
None so far in years :-(

The latest 12C actually uses an Atmel ARM processor (as in the new
20B) running the original 12C ROM using the Nonpareil emulator:

Rumor has it further Voyager models (11C, 15C etc) will be re-released
with this method.

Considering the cost of aircraft parts- an arm and a leg- it might be
possible to overlook such evidence of prior owners.

You get what you pay for?

They can still be recycled after the last ferry flight to Tucson ;-)

I don't think that kind of ceramic package is used for anything other
than prototypes. So you would recycle them for in house use.

There is a boneyard near the old El Mirage airport near Lancaster. I
got permission to tour it a few years ago, but no photographs.
However, there are photographs from the outside the fence on the net.

You may remember these guys for getting busted by having scraped
F-14s, a plane used by Iran, which just would love to get spare parts.

I think the place has new owners, so I have no idea if you can tour it
anymore.

The old HP (not the Chinese outsource Carly Fiorina HP) had the
attitude that the cheapest thing they made reflected on the entire
company. Thus even a calculator was made to HP standards. I was
dealing with HP of old regarding ESD, and nothing left the factory
unless every external pin could handle 30KV. If it took some
protection devices, so be it.

How does the ARM.based version compare with the old version,
in terms of speed and battery life? I would not be surpised to hear of
an 11C that was still on its original set of batteries :)

I haven't head about the new 12C as apparently it's quite hard to find
and identify them on the shelves, and only sold in Europe or somewhere
so far?

If the new 20B is anything to go by (and it should be because it's the
same processor) then battery life it will be a shocker.
Rated 9 months from two CR2032 batteries.
IMO HP goofed big in the design of the 20B. It works at 30MHz for all
calculations (then goes to sleep), but that means 15mA or so from the
two CR2032 batteries. This means big losses in the battery internal
resistance when doing calcs.
When I queried one of the HP designers about this on another forum, I
got the response that the CR2032 batteries have an IR of 5 ohms (IIRC)
and everything was fine and dandy. Well, they must be real special
batteries they are using because normal CR2032's start at 20ohms IR
and go up.

I can dig out the actual figures I came up with from the other forum
if needed, but it was I think something like 30% at least of the
computational power wasted in the battery IR. Crazy design.

Also, there was some concern about the low battery detection logic not
working properly.

Dave.
