Hi,
I've had this 40-pin IC for a while now. The only markings on it are
(Motorola Logo)
SC 440 00 L
7532 H
The second one is obviously a date code. The regular Internet searches reveal
nothing. It came off a small board with an MC6810 128-byte RAM.
Anyone know what it is?
Thanks,
Alexis.

Motorola used the SC prefix for custom parts. There was no published data.
Rarely, SC parts were modified versions of standard parts.

IMHO HP _went_ down the tubes over 10 years ago when the test equipment
became 'Agilent' (Note, I am not saying that Agilent went down the tubes...)
It saddens me that a company who used to be known for making some of the
best measuring insturments around are now known for cheap printers and
scanners. And that they once made the best pocket calculators, now many
of their calculators are just badge-engineered models.

I bought my HP48SX for two reasons. One was that I needed the sort of computation it
could provide (e.g. matrix calculations) in a small unit with a clean user interface. The
other was that it was the last model (as far as I could tell) that had the correct color
for its buttons and logos. :-) I used TI programmables back in the late 70s because they
were more affordable, but always lusted after the HPs.
I completely agree that there is a visceral pleasure in holding and using an
original-series HP programmable calculator. It demonstrates that while a general purpose
computer is not simply a souped-up calculator, a souped-up calculator has significant
value. Even today.
I'm going to go get my SX and do some calculations... because I can. -- Ian

I got a 48GX for my 15th birthday and used the hell out of it through
college. (The color scheme's not as nice as the SX, I'll agree.) I'd
still use it today, but the LCD screen has started "leaking" -- there's
a neat blotchy pattern on the screen now which unfortunately makes the
screen rather hard to read. Probably not much I can do to fix it other
than find a replacement calc... (unless someone knows where to find
replacement LCDs...)
Picked up a 50G a couple years back and I like it... the keys aren't
quite as nice (and I really miss the big ENTER key) but the screen is
much nicer (better contrast & slightly better resolution) and it's
considerably faster. It's too bad HP basically gave up the calculator
market to TI, there's been no interesting innovations in the graphing
calculator market since the TI-92 came out in 1996 or so... but maybe
there wasn't much more to do there before they became general-purpose
computers.
The 48 still feels nicer in my hand. Those things were built like
tanks. Most of the weight of the 50G is in the batteries :).
The iPhone HP calc emulations are neat, but I can't imagine using one
(or any other touch-based calc) for any length of time unless I had
nothing else on hand. The lack of tactile feedback is a big turn-off
for me.

A friend of mine was cleaning out his closet a few years ago and tossed me
his old HP-15C. It's a fun unit. I probably don't exercise it nearly enough
but hearing that the current HPs are not what they used to be makes me want
to keep it in better shape now.

No, because the battery is not trivially replaceable ;-)
Right now, my iPhone 3GS, though I really enjoy it, makes me think of those
old Ricochet modems which are essentially useless because the service provider
no longer supports them.
Come to think of it, my iPhone 8GB and my original iPhone 3G are essentially
just iPod Touches now. I probably should jailbreak them.

According to this,
http://reviews.cnet.com/8301-19512_7-10115467-233.html
the CPU draw is around 180 milliwatts; I don't know if that includes the
PowerVR chip. The 3GS probably draws somewhat less due to its more efficient
core.

It's not from HP, but I'm the coauthor of the PRG-16C simulator sold by
Thomas Fors LLC. IMNSHO, our applications are better than the HP ones
anyhow, with two exceptions:
1) Ours don't come with an online user manual
2) Ours currently only work in landscape orientation (HP's 12C and 15C

The first versions ran on a saturn processor the same as the HP-71B.
The orignal Voyagers (11C, 12C, etc) used a _NUT_ processor, similar to
the one in an HP41. According to the datasheet there are differences
mostly relating to the different battery voltage.
Original 11Cs and 12Cs contained 2 chips. The smaller one is the Nut CPU.
The larage one is the ROM/RAM/Display Driver, always known as 'R2D2'.
16Cs are much the same, the 15C has a thrid chip which is extra memory.

It'll probably cost USD$15.00-20.00 or so in parts, though.

been inside one, though.

Told you, the 300 series (some) are fun too ;-) The DS is going to the painter half of august.
After that there will be more pictures.
I will take a look when you get it done ;-). The DS has

The first versions ran on a saturn processor the same
as the HP-71B.
The HP-12 is the only Voyager witch survived the 90th ;-)
I note with interest on
http://www.brouhaha.com/~eric/hpcalc/voyager/variants.html
that the 12C Platinum has a 6502-compatible core. That alone makes me want
to find one. Is this currently sold Platinum the same thing?

If you buy a 12C and it takes two coin cells (vs. one coin cell, or
three button cells), then it uses an Atmel AT91SAM7L128 processor with
an ARM7DTMI core, and runs a simulation of the original Nut processor
architecture.

No shipping 12C calculator ever used the Saturn processor. The 12C and
the rest of the Voyager family were designed before the Saturn was
ready, so they used a version of the Nut processor from the HP-41C
family, modified to run at a lower voltage.
Over the years, they redesigned it for cost reduction several times, but
until the recent switch to the Atmel ARM microcontroller, they were
using ASICs.
HP ACO division (RIP) reportedly did design a Saturn-based 12C, but it
was not put into production.

I'm a bit late replying do to travel and having to take some time to
recover from minor eye surgery. Thanks everyone for the kind words
about my projects. There are a few details that I should clarify:
The instruction set of the first-generation HP handheld calculators
(i.e., HP-35, HP-45, HP-55, HP-70, and HP-80) were documented in US
patents, so I didn't have to reverse-engineer that. The HP-65 adds some
additional instructions, and several other people helped with
reverse-engineering of those.
The instruction set of the "Nut" processor used in the 41C family, 10C,
11C, 12C, 15C, and 16C, was published by the PPC and CHHU user groups,
along with some internal HP documents, so I didn't have to
reverse-engineer that instruction set either. I did have to
reverse-engineer some other aspects of the Voyager (10C etc.) hardware.
I did have to do some reverse engineering of the instruction set used by
the two calculator generations between those, the Woodstock, Spice,
Topcat, and Sting series, which include the particularly well-known
HP-25, HP-67, and HP-97, as there was very little published information
on that instruction set. I also had to reverse-engineer the card reader
and printer control chips of the HP-67, 97, etc.
Thomas Fors LLC and AL Software are using my code under license in their
iPhone apps that simulate the 11C, 12C, 15C, 16C, and 41CX.
I did provide the 12C object code to HP for their effort to reengineer
the 12C on a new ARM-based platform that simulates the original
architecture. If you buy an HP 12C that takes two coin cells, it is the
new ARM-based design. However, HP did not use my simulation code. I
offered their engineer a little advice on details of the simulation, and
some sample code for efficient BCD arithmetic, but he wrote all of the code.
I was not expecting HP to sell calculator applications for the iPhone.
HP's applications are presumably using the same simulation code as their
new 12C calculator.
Best regards,
Eric

They were developed by HP. I wasn't directly involved, though I did
offer them a small amount of technical information to help them write
their own simulator for the original 12C hardware to run on their latest
hardware which is based on an Atmel AT91SAM7L128 microprocessor (ARM 7
core).
I am rather surprised that they have decided to sell these as iPhone
applications.
I'm the coauthor of the SCI-11C, FIN-12C, SCI-15C, and PRG-16C iPhone
applications sold by Thomas Fors LLC, and the i41CX and i41CX+ iPhone
applications sold by AL Software.

WOW!
I didn't know that part of what you had been up to!
I still can't comfortably use an iPhone (it needs modifications for HAC),
but the possibilities of porting 16c to Palm OS (Fossil/Abacus!) might
someday mean that I can retire my CFX400s.

Hmmm... I have the Abacus, though I don't routinely use it. I never
learned enough about PalmOS to do a port, though. Aside from the
iPhone, I'm currently doing development for the Android platform. I'm
willing to consider developing for the Blackberry Storm, and maybe the
Palm Pre. (Though personally I can't understand why people are excited
about the Pre, as it just seems like a "me too" product to me.)

to have all data consolidated into palm desktop and sync easily with the

palm pre. Maybe in two or three years :)

Hi,
Creativecreek has a HP RPN software for Palm OS, Windows Mobile and iPhone.
http://www.creativecreek.com/mathupro.html
I used the CreativeCreek on my Palm device and I continue to use my
vintage HP25 and HP34C "built to last" calculators. I recently
purchased the anniversary HP-35s. It's ok but does really compare to
the original LED models or the HP32Sii LCD model. I continue to be
mystified by people that use AOS/ALG (Algebraic mode) calculators.
Enjoy.

Yes, but the overall UI of the phone is nothing like PalmOS. It
looks
like the host software isn't much like Palm Desktop, either.
