Blumoto vs 8086 Trainer Plus

A Heathkit ET-3400 Simulator. The app simulates a Heathkit ET-3400. This was an inexpensive computer from 1977 for people to learn about computing and programming. With the app you can enter programs in machine code using the keypad and see the result on the 6 LED digits. It emulates the Motorola 6800 8 bit processor and contains the original ROM and 256 bytes of RAM

8086 Trainer Plus turns your iPhone and iPad into a hands-on microprocessor learning kit — the classic 8086 board every engineering student remembers, now in your pocket. WHAT'S INSIDE • Hex keypad + LED display, exactly like a physical 8086 trainer. • Tap-to-insert instructions: MOV, ADD, SUB, INC, DEC, MUL, DIV, CMP, AND, OR, XOR, PUSH, POP, JMP, LOOP, HLT and many more. • Real assembler that parses your code and executes it step by step. • Live registers (AX, BX, CX, DX, SP, BP, SI, DI, CS, DS, SS, ES, IP) with high/low byte views in hex, decimal and binary. • All nine flags (CF, PF, AF, ZF, SF, TF, IF, DF, OF) shown with plain-English descriptions. • 1 MB simulated memory with a scrollable hex viewer. • Execution log — every instruction with before/after state. LEARN BY DOING • "TRY IT" button loads the SUM loop demo (AX = 1+2+3+4+5). • Guided step-by-step tutorial for writing your first loop. • Numbers work in decimal, hex (33H, 0x33), binary (1010b) or character ('A'). • Sample programs: factorial, Fibonacci, memory copy, stack demos, compare & branch, bit shifting. • In-app "how to" cards explain every mnemonic in plain English. BUILT FOR STUDENTS • BTech / BCA / Diploma / Polytechnic microprocessor courses. • GATE, PSU and university semester exam preparation. • College labs and self-study. NO INTERNET NEEDED The full simulator runs on-device. Practice at home, in class, or on the metro. FEATURES • Editor with syntax highlighting and current-line marker. • Multi-line Program Builder — queue instructions with ADD, run with STEP or RUN. • Auto-detected labels (SUM:, LOOP1: …) shown as tappable chips. • Portrait mode on both iPhone and iPad. WHY 8086? The Intel 8086 is the foundation of every modern PC processor. It's the first 16-bit CPU most engineering programs teach — and understanding it makes x86, x86-64 and every debugger you'll ever open make sense.
