Read full description

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

Digital Simulator bitGateLab

Read full description

bitGateLab Digital is a digital electronics lab on your PC, phone or tablet: design a circuit with logic gates, watch it run live, get its truth table and Karnaugh map, check the timing diagram and build it on a 3D breadboard with step-by-step wiring. Everything works offline, with no account. DESIGN AND SIMULATE • AND, OR, NOT, NAND, NOR, XOR, XNOR and buffer gates; inputs, switches, push buttons, DIP banks, LEDs, LED strips and bar graphs, 7- and 16-segment displays, buzzer. • Sequential logic: D, T, JK and SR flip-flops, clock, crystal, counters, 555 timer, word generator, serial monitor. • Components: multiplexers, buses, ROM and RAM, H-bridge, motor, optocoupler, registers. • Group any part of the circuit into a reusable block with its own pins. • Undo and redo, copy and paste, named and colored wires, grid and automatic fit. TRUTH TABLE AND KARNAUGH • Type a boolean equation or fill in the truth table and turn it into a circuit with one tap. • Karnaugh maps from 2 to 8 variables, with groupings, canonical form, minterms or maxterms. • Step-by-step simplification naming each law applied, NAND form and Verilog export. • From the circuit back to the truth table or the Karnaugh map. TIMING DIAGRAM • Every input combination as a binary counter, with the hex value of each cycle. • A and B probes to measure intervals, X and Z levels, slopes and propagation delay per logic family (TTL, CMOS...). • Export to PDF. 3D BREADBOARD • Your circuit becomes a real build on its own: 74-series chips, resistors, LEDs, switches and wires on one or more breadboards. • Step-by-step guide hole by hole (for example 44i → 12i), bill of materials and net list. • Move chips, LEDs and switches where you like, recolor wires, isolate a net or a single wire, undo and redo. • Labels on every input and LED, free rotation, zoom and image capture. MICROCONTROLLERS AND PROGRAMMABLE LOGIC • MCU51 (8051-compatible) and MCU14 (14-bit): program in C or assembly, assemble and single-step with registers, ports, timers, interrupts and UART. • 16V8, 20V8 and 22V10 PLDs: equations, fuse map and JEDEC file. • Ready-made examples: counters, blinkers, traffic lights, serial communication and more. SHARE AND SAVE • Save your circuits with version history; share them as a file, a link or a QR code. • Export images as SVG, PNG, JPEG, WebP or PDF, and code as Verilog. • Number systems calculator, two's complement and binary operations with flags. FOR LEARNING AND TEACHING • Reference of boolean algebra laws and theorems. • State table and state diagram of your sequential circuits. • Large-button interface, comfortable on PCs, phones and tablets; light and dark themes. • 16 languages: Spanish, English, Portuguese (Brazil and Portugal), French, German, Italian, Russian, Polish, Dutch, Turkish, Chinese, Japanese, Korean, Arabic and Hindi.
