The TI-59 is not particularly rare so there are still quite a few available. This makes them relatively inexpensive considering how advanced it was for it's time. The real challenge is getting a working battery pack. A rebuilt one could cost you more than the calculator itself so, be prepared for that expense unless you can rebuild it yourself. The chargers can be a little hard to find because the charger that works on the TI-59 also works on quite a number of other TI calculators. That's actually good news. I was fortunate to find my example in remarkably good condition with orig. case and completely functional... except for the mag. card reader/writer. The motor works but it won't pull a card through. I plan to disassemble and see if I can clean/repair but I have serious doubts. The card reader/writers on these units were flaky even when they were brand new so... This was simply an addition to my modest collection of 1970's calculators. I had one in high school and used it at college so it was a must-have for me.Read full review

These battery packs work great with old Texas Instruments SR-50 and SR-51 (and their A variants, the SR-50A and SR-51A) calculators. They recharge fine in the calculators and hold their charge for many months if they sit unused. Their construction is of new materials and they fit well in the calculators, though it can be difficult to get them to "snap in" on the hard-to-find SR-51 model and the SR-51A model. Sometimes I've had to remove the backs and snap the battery pack in and then put the back on the calculator. I used an SR-51 calculator with one of these that had sat for a year and a half and it worked immediately--no recharge needed, unlike the original TI NiCd packs.

The TI-59 calculator and PC-100C printer were used by engineers in the late '70s and '80s. It is a great product and indispensable at the time. It was almost like a personal computer. This system allows you to make your own software programs or use existing modular programs. You can view the results on the calculator screen and/or the printed output.

i used this machine in early 1970s. Before that, i used five (yes 5) Sinclair programmable calculators (only 16 programmable steps each) in sequence; enter raw data in the first one; then enter the result in the second one etc and get the result from the 5th one. The whole process had to be very carefully planned because there were no prompts for data entry and the program had to be entered each time the Sinclair machines after they were switched off but the system worked effectively and results had to be manually written down. With the purchase of the TI-59, all that changed, the program had to be written and entered only once then written onto the magnetic card and loaded into the machine whenever needed. The system had only rudimentary prompts for data entry but even that made data entry life a lot easier; the advent of the printer made it even better - not mistakes in transcribing results. In that age, the machine was fantastically ahead of its time; unfortunately in this age of PCs and MS EXCEL, it has become obsolete but is A PRIZED RELIC for me. in all honesty, I could not recommend this machine for current use because PCs and current technology have superceded its usefulness.Read full review
I think the TI59 was the greatest programmable calculator ever. BUT. They have not aged well and my experience with used ones has been bad. TI regards them obsolete and has "better ones". I regard the modern ones the devil to use. AND alas, the computing community thinks ordinary people should not be allowed to program computers. They think they are entitled to union shops as we had 500 years ago. So be prepared to pay big bucks for specialty packages, or big bucks for Maple or hire a programmer. If you need to pass a SAT test, good luck.
The Ti 59 is perhaps one of the most collectible programmable calculators from the Seventies. The PC100c printer is a great addition since you can printout any programs you've written and debug them easily. The printer also has a charging port for the Nicad battery packs. I have approximately 15 of these beauties! Highly reommend anyone who collects and uses calcualtors will appreciate this set up!
This is the classic TI to own for sure if you collect nostalgic calculators. This model was the world's first truly capable programmable calculator (up to 1000 key-stroke steps and huge memory for its day) with a ready made plug-in library for application specific problems. Professionals from a variety of fields, including medicine, engineering, business/accounting, surveying, science and math, oil/gas/energy, and even the military depended on this handheld computer to get the jobs done - especially those field-intensive jobs where desktop computing of the day was impractical. This is a real collectors item - I hope you can find one and hang on to it - it's a real great piece of American nostalgia.
Arrived in good condition; well-packaged. I took the old battery pack out and sent it off for "reconfiguration" so the calculator can now run on rechargeable AA batteries. Took a "dead" calculator and now it is completely functioning. Thank you to all involved in helping me obtain this goal and get a great calculator that, now, has a new life!
