Relive the classic 1977 Programmable 57 pocket calculator — faithfully recreated for iPhone, iPad, and Mac. my57 is a cycle-accurate emulator running the same ROM microcode as the original hardware. Every function, every keystroke, and every quirk — including its number formatting and error-blinking display — is reproduced exactly, not reimplemented. AUTHENTIC HARDWARE • 12-digit red LED display with a diffuser-glass texture and optional LED Glow • Real Speed mode runs at the original ~5,000 cycles/second, or switch to Turbo for instant results • Two documented factory ROM revisions (rev0/rev1) to choose from • Algebraic Operating System (AOS) entry, exactly like the original FULL PROGRAMMING SUPPORT • 50 program steps with LRN (Learn) mode • 8 addressable memory registers • GTO, subroutines (SBR), conditional branches (x=t, x≥t), and Dsz counting loops • Scientific notation, trigonometric functions, logarithms, and statistics (mean, variance, standard deviation) BEYOND THE ORIGINAL • Program & Memory panel — see every step's code and mnemonic, edit registers directly, insert/delete steps with undo • Saved program library — save, rename, and organize your programs • Share programs as .my57 files via Mail, Messages, AirDrop, or any app • iCloud Sync keeps your programs, registers, and library current across every device BUILT-IN USER'S GUIDE A complete guide is right inside the app — covering the interface for newcomers, plus a full programming tutorial with worked examples (loops, subroutines, factorials, linear regression, and more) for anyone who wants to actually learn to program it. DESIGNED FOR EVERY DEVICE • iPhone: portrait, full-screen • iPad: side-by-side program panel in landscape • Mac: resizable window with full physical keyboard support
