Getting started
Getting started with Calc-U 59
Install the app, load a state file, drive the printer and card reader, and find your way around the debugger.
Calc-U 59 runs the original Texas Instruments ROM, so the calculator in front of you behaves the way a TI-59, TI-58 or TI-58C did in 1977 — the same AOS arithmetic, the same 480 program steps traded against 60 data registers, the same Solid State Software modules.
Most people need three things: get the app installed, open a state file, and know where the printer and the debugger live. Each is a short page.
01Setup
Installing on iPhone and iPad
Install from the App Store, pick the calculator model, and open .ti59 files from the file picker.
02Setup
Installing on Mac
Download the release from GitHub, drag it to Applications, and get past the first-launch Gatekeeper prompt.
03Files
Loading a state file
What .ti59, .ti58 and .ti58c files contain, and how each section — partition, program, registers, keystrokes — is applied.
04Hardware
Printer and card reader
The PC-100C panel in dot and text view, printing and advancing paper, copying the strip, and where card files are kept.
05Debug
Using the debugger
The CALCULATOR, CPU and LOG tabs, freeze and step, F.START, and binary trace files for offline analysis.
