Hi Nigel
I've seen your site, is very interesting!
Do you know that there exists an ANITA VII ? I know a German owner of it. It
has 2 DECITRON tubes instead of 1 in ANITA VIII.
Do you know where to get a new (old) DECITRON for ANITA VIII?
I do have an ANITA VIII, but "heart" is weak. The same for NIXIE tubes, but
I can replace them by better ones (if I had time...).
There exists a lot of mechanical calculators and adders with L/s/d, but I
don't know electronical. I will publish my short article about non-decimal
calculators and list next time in HBW. I'll inform all list members. (more
info about our club: see http://home.t-online.de/home/ifhbev/start.htm ).
BTW: Heinz Nixdorf Nuseumsforum ("HNF") is in WEB:
http://www.hnf.de/index.html .

I don't think so. For one thing, there's no enter key. For another,
I've seen calculators with keyboards like that and they were algebratic.
To multiply 2 times 3 you would press (2) (X=) (3) (X=). (The last key
could be any of the keys that have = on them.)
You could check Guy Ball's website. He has a list of non-HP RPN
calculators and his book and maybe his website would have pictures of them.
In fact, if you had a copy of his book there's a good chance that you could
find a picture of your keyboard if it's for a calculator with a non-LCD
display.

Kevin,
I asked a couple of friends in Germany about TTCalc and here is one of
them's reply:
"I found the program with ftpsearch yesterday. Really nice. Unfortunately I
didn't
find the import option in the help file til now. Maybe there isn't any? I ll
continue checking
Reinhard"

Yes, it seems to be more like a WriteALL (WALL) file.

If it is a WriteALL file then you probably can't manually create a .MEM
file, but there should still be a way to import a program file. But
they're probably not .MEM files.

Hi Joe,
Thanks for the response. I'm in the same boat you are, I haven't used
it for ages, and I can't remember who showed me how to use it. FYI, If
you run ttcalce.exe instead of ttcalc.exe you should get the version with
english menus.
The .MEM files appear to be an image file of the calculator. As long
as I enter a program through the emulator I can save it to a .MEM file
using the menu, but I still haven't figured out how to make a .MEM file
outside of the emulator.
I'll try the HP Museum forum.

Kevin,
You might post your questions to the newsgroup comp.sys.hp48
(iirc). I used to be active there; they might not mind an
HP-41-style query. Apparently, the HP-48 is an absolute blast to
hack!

Hi Kevin,
I have TTCALC but the .HLP file in mine is in German also. The readme
file says that the author hoped to have an English edition out by the
middle of 1994 so hopefully it is out there somewhere. But I think that
the English instructions for importing text are in it somewhere. I'm sure I
remember reading them at one time. I think all you had to do was to write
the command into a .MEM file and then tell TTCALC to read it using the
standard HP 41 commands. Sorry I'm vague on details, I haven't used it in
a LONG time.
You might try posting your question on the HP calculator museum's HP
forum page.
I was just fooling around with it and found that the author's name,
phone number and E-mail address are in the ? function menu at the top of
the keyboard. Try E-mailing him or ask someone in Germany if they can call
him. I know several people in Germany if you don't.
More. I found that you can open a file using the menu. Use DATEI,

I tried creating a .MEM file of commands and reading it in but TTCALC
didn't like it. I'm probably missing some the needed special characters in

Hello,
Does anyone on this list have experience with TTCALC (it's a Windows based
HP-41 emulator).
I am using ver. 1.3. I am trying to figure out if you can import the text
of a program into TTCALC,
(and more importantly, how to do it) but the help files are in German and
neither my high school
German or my TOLKEN99 translator are up to the task.
On another note, does anyone know of any other Windows or PDA based HP
calculator emulators
out there?
Thanks,
Kevin FitzGerrell
Dear all.
My Name is Friedrich Diestelkamp from Munich, Bavaria, Germany.
When transistors came up in Germany I tried to build up my own radio.
When electronic circuits arrived I built up my first clock.
When I got a Walther WSR160 from a friend I started to collect mechanical
calculators.
When I saw first electronical calculators disappearing from market I started
to collect el. pocket calcs.
When my cupboard crashed down I decided to collect small calcs instead of
big ones.
When HNF Heinz Nixdorf MuseumsForum in Paderborn asked me for el. pocket
calculators I handed over nearly all of them (ca. 900).
But I love all types of calculators! So I'm in 3 lists .........
At the moment I stress on slide adders and small mech. calcs.
ADDIATOR is my favorite company. But I'm looking for all simple / flat /
primitive adders without automatic carry. If you do have one please let me
know! BASSETT, CABROL, KUMMER, TRONCET, what ever, send a scan.
For trade / exchange I could offer electronical calcs, slide rules and
duplicates of my collection.
Best regards, Friedrich

I too have a BP-8 with the battery connectors. Unfortunately it is
completely dead. The BP-8 has circuitry to produce 9V DC (I think) from
the 2.4V you get from the 2 nicads.
I have been considering wiring up my good BP-8's to allow them to be
used in calculators with the 9V battery clip.
If your pack is not too far gone, it is simple and cheap to replace the
nicads.
Hmmm I'm sure all of mine are BP-8. What's a BP-7 or a BP-6?
Steve
My TI Programmer (LED model) came with a dual power system:
A BP-8 battery pack (2 rechargeable AA cells) and a separate
flat battery door. The connectors from the battery pack and
from the circuit board inside the calculator were both
standard 9-volt cell snap connectors. So, you could use the
rechargeable pack or just snap in a 9-volt battery and lock in
the flat door over it.
This led me to try the 9-volt cell on other TI calculators
with BP-7 packs and they work just fine. You just push the
wire ends from a standard 9-volt snap connector into the
little rectangular plug from the calculator board (red to
black, not red to red.) The BP-7 packs are easy to dis-
assemble (snap fittings.) Remove the rechargeable cells
(which you should do anyway) and the little circuit board
inside. The remaining battery compartment door is flat enough
to fit over a 9-volt cell positioned carefully in the
calculator.
It's a handy way to have a self-contained battery operated
calculator for testing or demonstration. I gather that the
chips are not that voltage sensitive and no doubt the cell
voltage drops considerably under the LED load. Do this at
your own risk, of course, as I have no idea what any specific
chips can handle. I have tried this successfully on an MBA,
SR-50, TI-55 and SR-51-II. This last has a BP-6 pack and you
connect red to blue and black to green.
I collect HPs and others, when I can.
At the moment I've got one more 9815 than I need - if anyone's
interested (especially if you're in England), let me know.

Yes we get it & do appreciate it!!!

Hi everyone,
Its good to see so much activity at this new old-calculator group !
You may be interested in a new internet site featuring lots of photos and
details of a selection of desk calculators (mechanical and early
electronic), British calculators (hand-held & desk, eg. Anita, Prinztronic,
Sinclair), and mechanical British Sterling Currency (£sd, ie. non-decimal)
desk calculators.
The address is http://freespace.virgin.net/nigel.tout/
Looking forward to interesting discussions at this new group,
Nigel Tout
nigel.tout@...
Oh, whatever YOU did expect, Im not dead ;)
Still reading the posts, but the needed time for redesigning my site just is
out of reach. Sorry about that.
Frank
www.elektron.net
If we're trying to find out who is on the list, you can add me as a loyal
member.
My collecting focus is on early LED/tube-type portable/pocket electronic
models (1970s vintage) although I've strayed to some early LCDs -- like the
early Sharps, Rockwells, and some yellow LCDs -- and some modern novelty
calculators -- shaped like pool tables, stars, M&Ms, characters, and the like,
as well as novelty uses like tape measure combos.
I'm still trying to get one of every LED/tube-type pocket model out there.
Thanks to friends in all parts of the world (and ebay, of course), I'm
continuing to be successful finding new models.
My interest came about because I thought the designs and styles were pretty
cool. I'm intrigued by the different ways designers & manufacturers thought a
calculator should look like (at least in the early days).
Most of you know about our book, Collectors Guide to Pocket Calculators, and
my website http://www.oldcalcs.com/ .
I'm a southern California transplant from scenic North Jersey (though I can't
remember what exit off the Jersey Turnpike anymore).

William, your name looks quite familiar (Linux-List, too?); I trust
you, and other Oldcalc list members know about the other calculator
list, devoted to mechanical machines? One of these days, I'll send
off the magic command that replies with the public subscriber list,

(subscription to both) there is.
I surely hope that here is no sense of competition between the two

What do you know about the Canon Canola SX 320 calculator/computer? I
have one but I haven't been able to figure out how to use it yet. (It's not

I heard about that. What the hell happened?!
I started out collecting HP hand held calculators but then started
picking up the desktop models, then the bigger stuff then a few old
computers ... Well the next thing I knew I couldn't walk through the house!

Hi all,
there is someone else on this list, like on the list before. Mostly
listening, seldom speaking. I am collecting old electronic calculators,
namely HP. No LCD, only LED, no mechanical, only electronic. Besides HP I do
have some Ti and some other models. My main interest is "complicated"
models, scientific or financial.
Greetings,

Hi Jay, William and Joe,
One more here. I collect slightly newer calcs, mostly pocket
programmables.
HP-41 & 71, TI 58 & 59, Sharp 1250 & 1500 etc... Looking for a
printer/cassette
drive for a Sharp PC-1250 now, it would be the CE-250.
Joe, got the TI PC-100 tuned up and running great, thanks for a nice
machine.
Can you believe how much these were going for on eBay with a TI59 last week?
Don't know what happened but they went from can't hardly give them away to
$100+ items!

Hi Jay and William,
I'm still here. I collect HP calculators including the big stuff like HP
85s, 9825s, 9845s, 9100, etc. But the collection is growing, last week I
picked up a HP 1000 and a Silicon Graphics Indigo. I also have some S-100
stuff; two Altairs, two Compupros and a Zenith Z-100.

In horology and electronics, companies love to occasionally show off
their technical ability by making the thinnest-possible products.
One wristwatch was so thin it wasn't wearable; it would bend.
As to calculators, the Casio SL-800 is of particular interest; it
has the exact height and width (as well as the rounded corners) of a
credit card. A crude check with a metal rule shows it to be roughly
0.7 mm thick; maybe 1/32". (I was surprised, just now.)
Its construction reflects fairly-recent special design techniques in
the electronic industry; lots of films of various kinds. Its LCD is
very sensitive to external pressure and minor warping of the whole
calculator. (It's commendably stiff.) It has a four-panel solar
cell, and the following keypad layout; it displays 8 digits.
Use mono-spaced font, Latin-1 charset. (÷ = divide, × = mult.)
[7] [8] [9] [÷] [%]
[V] [4] [5] [6] [×] [MR]
[C] [1] [2] [3] [-] [M-]
[AC][0] [.] [=] [+] [M+]
V= square root symbol (not in the Latin-1 charset)
Looking at the back, it's black and glossy, with fine yellow line
decorative patterns, and a red stripe (with an arrow!) suggesting
the mag. stripe of a credit card. Whimsy was alive at Casio! By
reflected light arranged to reveal any surface profile, there is
little evidence of internal structure.
However, reflected light (again, aligned to reveal surface
profiles) from the front shows lots of details; a row
of little internal "bumps" for the LCD connections, and little
membranes for the key pads; the "wells" under the membranes have
plainly-visible borders. I keep mine in a Canon credit-card calc.
protector; a note inside says that the IC ("chip") is connected (and
mounted?) by TAB (tape automated bonding, fairly sure). It's not at
all obvious where the IC is. (Dental X-ray, anyone?:)
As a practical calculator, it is, sad to say, probably too fragile
for ordinary use. Kept carefully in a protected place, it might last
better. I have tried to do the latter (although not using a
protective box just its size, but the protective cover I mentioned)
I've kept it in the front well of a roll-top wooden floppy container
for many years, and it has been wounded, nevertheless. It still
works. Its display has a dark patch, and seems particularly
sensitive to external forces.
I might still have another, in its original packaging, unopened.

The Casio AL-8 (AL-10?) was a fluorescent-anode handheld with lovely
keys; did square root and fractions. I love the way it will take the
sqrt. of a ratio of perfect squares, such as 4/9, and keep it in
fractional format. It returns 2/3 as a result, fairly sure;
definitely a fraction, not a decimal approximation. This is
quite unexpected, because when "pushed" it reverts to a multi-place
decimal representation that may be exact or an approximation. In
doing this, it abandons the fractional representation.
Fwiw, I have a small stash of electronic handhelds, mostly stored in
places not really known until I go through my stuff.

A calculator fan wrote me a message asking for information on the
calculators used by the characters of the TV series Galactica in 1977/78.
I have posted the request along with some pictures in the billboard at my
web site:

Please see if you can provide him with the information.
Thanks!

Hello,
I don't see that anyone else has joined here. I'm sending this as a test to see
if anyone gets it. Welcome to the group.

Sorry, folks, I should hawe known. Kevan's List server had become
history :( when I posted this. However, Ernie got his copy.
The EC-132 was an EC-130 with square root.
Try evaluating sqrt(sqrt(9^2+((19^2)/22)))
= 3.141592652... (I trust)
This is one example of a whole collection of superficially similar
expressions I once saw, back in pre-HP-35 days; the idea was that
with constants/coefficients of only two digits (I don't think even
three), you could not only "create" an approx. to pi, but iirc, also
do transcendentals within usable ranges. These were called "onions"
because of the nested parentheses, which must gladden the hearts of
LISP enthusiasts.
(Hi, Ernie!)
If, as I think it does, the EC-132 manual (I think Ernie J. has some
reprints)
[P.S.: Ernie says he has EC-130 manuals, but not those for the
EC-132. Sorry! -nb]
... the EC-132 manual has some extraordinarily-interesting
expressions of this general character that make full use of fast
square roots. It's quite likely that the Friden EC-132 was the
fastest evaluator of square roots for some brief period of time.
Making fast square roots as easy to get as sums, differences,
products, and quotients brought out some fascinating ways to make
use of the fifth function.

Hi All,
If this has worked then I have setup/transfered the ecalc mailing list to
egroups. Unfortunately the name ecalc was allready taken, so I have named the
group 'oldcalcs'. So the address for the group is now oldcalcs@egroups.com
