KEYBOARD OVERLAYS (Premium)
The plastic overlays that came with the TI-59 are here. Slide the factory Key Code Overlay over the keyboard to see every key code while you program, or create your own overlays and label any key for your programs, just like the sheets that came with the Solid State Software modules.
A KEYBOARD TRUE TO THE ORIGINAL
The keyboard is now laid out from measurements of a real TI-59: key size, spacing, margins and the frame around the keys keep the calculator's proportions on every iPhone, iPad and Mac. Keys respond to a tap anywhere in their cell, so small keys are easy to hit.
MAGNETIC CARDS
• You choose which side of the card to write; the bank number is recorded on the card, as on the real machine.
• A card can be read while the calculator is idle, without entering the bank number first.
• The card list opens without a library module, and a card appears in the card slot after it has been read or written.
• The save dialog explains which program steps each bank covers.
ALSO
• LED display with a diffuser-glass texture and an LED Glow option.
• Bug fixes and refinements throughout.
