It´s Version 2 Datamath,sticker in the backside is similar to Spanish made V2,but it has written "Made In Italy" down below in left. Today i got my own TI-2500 datamath and this thing is super awesome,but i noticed that you don´t have it on your site. I´m young Estonian vintage collector and i´ve been visiting your site for some month and i thank you for this fantastic work. I have a good story about that if you are interested.Īpril 18, 2015: TI-2500 Datamath V2 Made In Italy
The first time we used it was for the Harrier CROM, which you talked about in your article.

When I was in CEC I designed the software development system used for CROMs. I also designed the production CROM tester. I designed the magnetic card writer for mass producing magnetic cards for the TI59. Most of my work was still with calculators. I left the Consumer Products Division and joined the TI Corporate Engineering Center. Lubbock was the primary manufacturing center for TI consumer products in the US. Whe the consumer products division was formed, Consumer, Business, and Scientific calculators were brought together. I designed production test equipment for almost all TI consumer calculators. We then moved to the new large TI plant located North of town. I moved to Lubbock, Texas when we opened the manufacturing facility in an old Cooks department store. At that time calculators were part of the Semiconductor Division. I joined TI in 1973 as a test equipment design engineer. I notice the site is quite old, are you still active with the site? PS: I also had a TI-66 before I bought my original TI-55 II but had lots of trouble with the keyboard and finally tossed it. Would this be considered "rare" ? I'd love to know anything interesting that you can share about it.

I replaced that one with a 1991 TI-35X, which I've been using since then, but I thought it would be fun to go back to a TI-55 II since I liked the tilted display better.Īnyway, this one from Ebay is marked as a TI-55 II (with no dash) and on the back shows "Assembled in Taiwan" and has a date code of C-0185 and a serial number of 0099748. I just bought it for fun, since I had one of these calculators in the 80's and loved it - until I spilled a can of Coke on it and the keys became forever sticky.
I thought that I would share some info and a couple pictures of the TI-55 II that I recently bought on Ebay. I was looking for information on my TI-55 II and found your awesome website! This calculator got me through school, sixth form and then university followed by two post graduate exams a few years ago. My wife doesn't believe me but the battery is original and it still works. May 31, 2015: Texas Instruments TI-30 IIIĬame across your website when trying to work out when I bought my Texas Instruments TI-30 III. The rechargeable battery and charger was not available right away in the US. The first ones came with only the 4 AA battery holders. I still have my first one and it works as good today as it did the day I got it. I was a Canon USA Dealer then and received my first LE-10 for demo in late 1971.Īs I recall and my records seem to substantiate, the Canon suggested retail price was to be $395.00, which was later reduced to $295.00 by Canon. Trying to fire up my old calculator for both museum and practical purposes, thank you for a great online resource! Had to use power supply as the BP-78 is missing.
Im standby verbraucht der nur 19 Mikro Ampere - das reicht für 7 Jahre. Ich betreibe den nun aber mit einem 9v-Block. Vielleicht ist das noch interessant für deine ic Liste. Ich hab einen sehr alten Programmer (LTA4877) mit dem Za0675 chip.
You may like to correct the battery type information on your model information here: Your site is great, with a lot of information. I tried to insert 2 x LR-44,but it is impossible as it doesn't fit. It uses 2 x LR-43 type as indicated in the back cover. I have just acquired one of these machines, and I have an information concerning the batteries. I just changed my battery this month (November 2016) for the first time that I can remember, since purchasing it back in the day. NNovember 18, 2016: I have a TI 1100 II calculator Used fairly regularly, still sits on my desk fully functional and interestingly still on the original battery!
