89I to IFF Conversion: FAQ

What are 89I files?

The 89I file format corresponds to raster images created using the TI-89 graphing calculator developed by Texas Instruments. This powerful calculator is popular among Science students, engineers and other professionals who need to process complex mathematical calculations, including algebraic and trigonometric functions, matrices or graphs. The TI-89 model was the successor of the TI-92 model and it included a Motorola processor.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s.
