Don't expect the card reader to work. :)
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.Verified purchase: Yes

Enhanced battery packs newly manufactured
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.Verified purchase: Yes

Great Calculator/Printer
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.Verified purchase: Yes
