A computer made completely out of logic gates. Version 2. V1 can be found here: https://circuitverse.org/users/13948/projects/49969
Because of the limitations of the circuitverse.org simulator, and for easier use, some inbuilt components are used (like the 256-byte RAM module), but most of it is made up of OR, AND, NOT, XOR, NOR and NAND.
This project was originally made for my profile project. This is (or will be) version 2 of the 8-bit computer.
I finally did it.
I made my own 8-bit CPU! With a bit of inspiration from other CircuitVerse projects and from a book called, Digital Computer Electronics.
The premade program does this: 12 + 6 - 3 + 2 (which equals 17)
program the computer by typing in the opcodes in the ROM
Opcodes: (X = address)
0X = Load X's value to Accumulator
1X = Add X's value to Accumulator
2x = Subtract X's value from Accumulator
ee = Take Accumulator's value and put it in the Output
ff = Halt/stop everything
Versions (Date format: DD/MM)
9/11 v1.0 - Finally finished it!
BRWD: BINARY READER AND WRITER DEVICE
How to use:
1. To start writing, set your clock speed, and turn on the "Writer" switch.
2. To scroll through the memory, turn on the "Scroll" switch. Press "Reset" if you are ready to read.
3. Turn the "Writer" switch off, and turn on "Scroll" to start reading the binary.
4. Then when you're done, press "Reset RAM" to reset your writing.
