a PDP-1 implementation in FPGA:

DEC PDP-1 is a computer designed and produced in 1959. Considering the pace of change in computing, that might seem like the prehistoric age. However, it is also surprisingly modern and proves a point that the basic concepts still withstand the test of time.

This project is trying to re-create this computer in FPGA and enable running the first real computer game, SpaceWar!, on a modern display and gamepad. It is designed to run on the MiSTer platform, a retro gaming system based on the Terasic DE10-Nano FPGA board.

The implementation is done in Verilog, a hardware description language specifying the structure and behavior of digital logic circuits. This is not a software emulation because there is no CPU executing it.

Since this is my first Verilog project ever and its purpose was to teach myself about FPGA, don't expect too much. Beginners often make mistakes or break best practice. Please keep this in mind. Advice and suggestions are welcome!

A programming language for E. coli
Mind = blown.
MIT biological engineers have created a programming language that allows them to rapidly design complex, DNA-encoded circuits that give new functions to living cells. Using this language, anyone can write a program for the function they want, such as detecting and responding to certain environmental conditions. They can then generate a DNA sequence that will achieve it.
"It is literally a programming language for bacteria," says Christopher Voigt, an MIT professor of biological engineering. "You use a text-based language, just like you're programming a computer. Then you take that text and you compile it and it turns it into a DNA sequence that you put into the cell, and the circuit runs inside the cell."
