Texas Instruments TI BA-II Business | Vintage 1980s | WORKS

Vintage Texas Instruments BA-II Business Analyst II financial calculator, made in the USA circa 1980 (confirmed by original purchase receipt dated September 5, 1980). The calculator is in good vintage condition and fully functional. Display is clear, and all keys respond properly, however the buttons are HARD to push. The calculator body shows light surface wear typical of age, with no cracks or major damage. The protective case is included and in fair condition, showing some wear and fading from use. The original owner’s manual and sales receipt are also included — a rare find for collectors.
