Recently I found myself reminicing about the toys I had growing up. I was so pleased to find the TI site had exactly what I was looking for and then some. I had completely forgotten about the Little Professor calculator I received in my stocking one year until I visited the datamath section. I found it absolutely amazing and was very appreciative of the fact that you have sound clips from the original Speak & Spell, which again I remember playing with for hours. So I wanted to say thank you for bringing back the memories and to ask you if you might know where I could find these products now. Any information you have will be greatly appreciated. Thank you for your time. Sincerely, |

Dear Sir: My wife and I received an SR-50 calculator as a wedding present in 1975. I am trying to refurbish it and I found a great deal of useful information on your datamath website. I appreciate it. I am trying to locate a replacement for the AC9200 charger for this system. My local electronics store, Radio Shack, was very confused by the specifications for this charger. I would appreciate an answer to two questions: 1) Does the charger change 120V AC current to 8V AC current or 8V DC or, saying it in another way, does the SR-50 require 8V AC current to recharge its batter? It appears from the datamath web site that 8V AC current is needed. 2) Where can I purchase a AC9200 or equivalent? Are there any other suggestions you might have. The physical condition of my SR-50 is good, however, I have not been able to operate it in years because the battery pack died. The reconstruction of a BP1 battery pack on the Web site is very helpful. Thank, Alan A. Schreier PhD |

I want to compliment you on
your very excellent site. It has historical significance. It
is a source of important info, such as- how to rebuild a battery pack!
Unfortunately many of these excellent machines end up in a drawer due to
bad batteries. I have obtained several fine specimens along with
bad battery packs which I will rebuild. My first calc was a SR-51A
for Engineering school (really wanted an HP-25) but the 51A proved to be
a better tool. I still have it in very good condition. I
have recently obtained several examples of the TI-59 Programmable and it
seems that they tended to have problems with the card readers. A
section on servicing the card reader mechanism would be helpful.
Maybe I can contribute my own experiences. |

Joerg, Just a note to tell you what a nice web site you have for such seemly obscure desktop items as calculators. I did a quick search on the web for my trusty TI-5015 and your site came up on top. Actually as the only site for vintage calculators. My calculator dates back to 1980, when I purchased it new as a close-out sale from a local ham radio flea market. Used every year since, this calculator never ever skips a beat, and just keeps on working fine. I have no plans on replacing it, nor do I see a suitable replacement for it made today, with its no-distraction lack of digital display and its nice desktop size, keys and functions that make it the perfect accounting calculator. Best Regards Bill Greeley |

I just discovered the Datamath Calculator Museum site, and wanted to tell you how impressed I am with it. Great info on all those vintage TI calcs. I've used the site a lot when searching for calculators on Ebay to compare the features, battery packs, AC adapters, etc. On the Product Manual page, you ask for suggestions about what manuals to add. I need manuals for the TI-55 and TI-57 (in English). I've looked on the official TI web site but can't find them. So, there's a suggestion........... Thanks again for all your work on the Datamath site. Keep it up! Guy Nelson |

Dear Mr. Joerg, First I want to thank you for your fantastic work with gathering information about Texas Instruments products. Even though I work on Texas Instruments Customer support and have access to different data bases I use your site on a daily basis to find information. I just discovered a small fault. The back up battery in the Voyage 200 is a CR1616 and not a CR2032. Thanks again for a very good web site. Malena Bohlin. |

Sehr geehrter Herr Woerner, mein Name ist Steffen Schöler und ich habe hier einen TI-30 LCD, der mit n! :-) ) von meinem Schwiegervater zu liegen. Die Tasten sind nur noch sehr schwer zu bedienen. Der Taschenrechner stammt aus seiner Studienzeit und er hängt sehr an diesem Stück. Wir, meine Frau und ich, wollten Ihm eine Freude machen und ihn reparieren. Ich war schon beim Uhrenmacher und habe auch schon mit Herrn Marcus Bering von Texas Instruments gesprochen, doch keiner wußte wie man ihn öffnen kann. Herr Bering meinte, Sie seien einer der Wenigen, der mir da noch helfen könnte: Wie kann ich den Taschenrechner öffnen, ohne ihn kaputt zu machen, oder reparieren Sie auch Taschenrechner? Über eine Antwort würde ich mich sehr freuen. Mit freundlichen Grüßen Steffen Schöler |

Hey, I had just purchased a TI-36X Solar before going to you site, and it raised a little interest to me about what are the real physical difference between it and all the other calculators with identical cases, like the TI-30Xa, BA35 Solar, etc. I bought the TI-36X even though I already have a TI-30X IIB, I wanted the extra functions of the TI-36 for my chemistry and science classes. It is a little frustrating not having that 2-line display considering I am used to my TI-30X IIB and TI-86 and TI-89Ti graphing calculators. I still need that pocket calculator like the 30X and 36X for some classes and labs. Anyway, your site answered some of my technical questions about the circuits and stuff. It is amazing the 36X I bought just now in 2004 is really the same as the 35X from 1991 nearly 14 years ago! The log bug in the 36x I just
bought was news to me. Kinda freaky, we all just assume our calcs
are pretty much perfectly correct but apparently that is not always the
case. Interesting information, something I would assume could
cause problems for some people. I know to watch out for it if I
ever have to calculate the situations presented in the table. Good site, hope you never shut it down, and I hope you keep it updated like you have thus far. It is just neat to see the little technicalities behind the instruments we use all day everyday. Regards, J. D. McGee |

Vor allem ist die ganze Sache auch noch saumäßig interessant. Ich habe zwar nur einen Hand voll TIs aber ich bin seit 15 Minuten am lesen und am Unterschiede finden und muß mal zwischendurch die Info ablassen. GENIAL, KOMPLIMENT !!! Wirklich saugeile Seite !!!

Hi, You have a fantastic site, and a very useful resource. Don't worry, I'm not trying to scrounge a link exchange! I have just obtained a TI Little Professor, mainly for my daughter to do a bit of arithmetic practice (using retro technology of course!). It is the 1982 UK model, and I was hoping to download the manual from your site, but the link doesn't work. Thanks again for providing a terrific and valuable site. Regards, Bill Ayers |

Hi Joerg: I just want to thank you so much for maintaining this TI museum. I'm a CPA in New Jersey and the 18 year old extension of my right arm know as the" TI-5160" was beginning to die last month. As I'm sure you know, TI exited the desktop printing calculator market a few years ago. I wish I could find a old "new" one, but I was not having much luck hunting. I settled for a Canon from OfficeMax and was not happy with it's "feel" or any other ones out there in the current retail market. After finding your site, I was able to identify some old model numbers from the late 90's that would suit me and searched the Internet for one, new or used. I could not find the TI-5660 I wanted new, although oddly there are people fighting over used ones on Ebay! Can you believe it! Eventually I found a "brand new" (old stock) TI-5640 (an LCD model made in Thailand) on Amazon that was not listed there a few weeks before. Could you believe it was being sold by some company only a few miles away from my office. It came yesterday and I was so thrilled I immediately ordered a second so I could put it in deep storage in case the new one ever fails. ( he's still got 2 units left!) So thanks again. I see that you are missing your TI-5640 photo on your website. So the least I can do is e-mail you the photo if you'd like. If your collecting I'll give you the link to where you can buy your own (good luck on the shipping to Germany). Regards, Fred N Boehm, CPA |

Dear Mr. Joerg Woerner, I recently visited your DATAMATH CALCULATOR MUSEUM webpage. What a fasinating page for someone who grew up in the 1980's. I wanted to know more about the Texas Instruments Speak & Learn Magic Wand. I was given one as a child, while it's not in the condition that it was in when I was five I would like to get a old memory out of it. I no longer have any books for it so I can't tell if it still works. It powers up with that pleasent greeting, but that is all I can get out of it. I originally had the Talking E.T. Wordbook infact I learned to spell my first word with it. If you have anymore information on this unit please write me back. Sincerely, Otto Bismark |

Hello again Joerg, I wanted to personally thank you for all the valuable information you've placed on your Datamath website. Until recently, I hadn't needed to take advantage of it. I bought a couple TI-55 calculators dirt cheap, not knowing whether they worked or not. I'm generally an HP/RPN fan, but the ol' TI-55 is special to me because it's the first calculator I had in high school in the '70s. It was stolen at college and I bought an HP-15C to replace it. If only I had checked your website sooner - it would have saved me a lot of fiddling around with a multimeter and a power source, trying to divine the inner workings of the BP-7 battery pack. The AC9132 adapter I have is toast, so being used to HP adapters I blithely soldiered on assuming the 5.7 volts output listed on its back was *DC*. "Gee, that capacitor sure is getting warm on the little circuit board..." Fortunately I didn't fry anything, and my brief experimentations determined that both TI-55's were operable. Not having a proper adapter, I'll probably just install a 9V connector in each calculator and use disposable 9V batteries. I'll watch out for the possibility that red=negative, as you've noted! Regards, Doug Trader |

Hi there! I was doing a google search in a frantic effort to locate a guidebook for my old calculator and happened across your site. I am amused to think this old thing is a collector now! The amazing thing is, it is still running on its original batteries!! Some of the buttons are worn off, so thanks for the picture posted to remind me. Got any ideas on what kind of paint I can use to mark them again? I haven't used this calculator since college in 1988 and I've recently enrolled in school again and had to dig it out. Anyway, I just wanted to say hello and that my old relic is still going. I may replace the batteries this weekend, it seems a little sluggish and I have a midterm on Wednesday - don't want to take any chances! Ciao, L.J.M. |

Hi there! Thanks a lot for putting a
picture of the Texas Instruments TI-34 calculator on the web! Mine
stopped to work after I passed it on to my daughter. I was a bit sad
because there is no good replacement available these days (10+2 digits,
works well in low light). So I took it apart and could indeed fix it.
But I would not have been able to put the keys back in their right
places if it hadn't been for your picture :-) |

Speak & Spell: Datamath Calculator Museum In jahrelanger Sammel- und Dokumentationsarbeit hat Jörg Wörner das Datamath Calculator Museum zusammengetragen. Hier werden hunderte Taschenrechner, von den ersten Texas Instruments Datamaths aus den ganz frühen 70er Jahren bis zum Mickey Mouse Rechner aus den 90ern, ausführlich vorgestellt. Besonders spannend finde ich die Abteilung Texas Instruments Speech Products. Hier räumt Jörg nämlich ganz nebenbei mal mit ein paar Mythen der Popmusik auf: Die von Kraftwerk auf dem Album Computerwelt / Computerworld verwendeten “Roboterstimmen” sind nicht etwa selbstgebastelt, sondern stammen aus dem Chip des TI Language Translators von 1980. Auch die Speak & Spell - Spielzeuge (Foto) haben Spuren in der Musik hinterlassen. Wie auf Gesamtkunstwek von Dopplereffekt finden sich auf unzähligen Electro-Releases Speak and Spell-Synthese-Samples. Und dass das Depeche Mode Debut Album von 1981 ebenfalls Speak and Spell heisst, ist wohl auch kein Zufall. |

it away. Then I found your site and was so pleased. You even have the

I wanted
to look up information on my trusty TI-35X, which serves my limited
needs as a web site designer, and found your site, and not only got the
manual that I wanted, but a wealth of other information as well about
the calculator, it's history, chips, etc. Having my first degree in
Classical Civilization (AKA - History in a dept separate from the
History dept.), I'm always interested in history, especially 'anonymous'
histories of the technical aspects of our lives - like the history of
the bath, irrigation systems or the mechanization of death
(slaughterhouses) - stuff like that. |

Joerg -
I must say - You made my day!!! Thank you. The timing was
outstanding and I had really not much optimism remaining as far as
getting a TI-5038 Manual. I'm
somewhat compulsive-obsessive when it comes to having instructions for
anything mechanical, electronic, or organic. I truly believe when
all else fails, read the book. Actually, when possible, I read
before starting with anything new. Again,
thank you for your efforts - what you do is very much appreciated. Bob

Hi, Your website is great. It's an invaluable calculator information resource. I just picked up the latest version of the venerable TI-30 the TI-30XS Multiview. It's great to see this further refinement of this class of calculator. When will you update your website to include this new version of the calculator? What I would really like to see is for TI to release a modern non-graphing programmable calculator. The graphing calculator is also well past due for an overhaul. I'd like to see a brand new model incorporating a modern higher resolution LCD display, a fast RISC processor, and plenty of flash memory. Wireless connectivity would be nice as well. (Bluetooth anybody?) Regards, Barry Reeves

Subject: Your site Just
came from your site. It was great and just what I needed. We have
this TI Hot Calc calculator that surfaces every now and then around
here. The decimal point is completely worn off, the minus sign is well
on its way as are the 1 and 4. 0 is on it's way as well as
fading/scraping marks are showing on the top row function buttons. This
past year whenever I happened to pull it out, push the ON button
and it worked, I was amazed and wondered just how old it was. This
morning I decided to try and find out. I started out searching the TI
site to no avail. After several google search inputs I found your site.
YIPPEE! There it was. I remembered being in Wal-mart purchasing
this calculator for one of our daughters, but couldn't even come
close to remembering what year. I guess I could have come close on paper
after a lot of calculating this and that (LOL), but that would have
taken forever. Thanks
to your diligence in cataloging these calculators, I found out that our
Hot Calc will be 14 years old this year. I used it again just this
morning to figure a book order amount for our youngest (16 yrs). Over
all, this is the best, cheapest, basic calculator I have ever
purchased. Thanks, |

compiling the entries. Thanks
again for the great help you gave me. I sincerely appreciate it.
I used my Business Analyst when I brokered real estate here in
Houston in the late 70s. It was a great boon to us real estate
people as up to that time we had to calculate amortizations using
factors to multiply times dollars. With the touch of a few buttons
we could tell how much a person could borrow or what the monthly payment
would be on any loan. I loved that little machine. John

wonderful Datamath museum. I especially enjoyed your
reminiscence about your letter to TI about the broken IC in the dice
circuit. Today we often are oblivious to the ways little events
can have big effects. Best regards, Keith |

also for all the hard work you do at datamath.org. It is a wonderful
resource for the TI collector. Sincerely, Jesse Dodd |
