8086 Trainer Plus

The 8086 microprocessor trainer, right on your iPhone & iPad. Type MOV, ADD, LOOP — watch registers, flags, memory update live. Perfect for BTech, BCA, GATE.

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.
