A Python Serial Terminal to Get You Out of a Jam

When fiddling around with old computers, you can occasionally find yourself in a sticky situation. What may be a simple task with today’s hardware and software can be nearly impossible given the limited resources available to machines with 20 or 30 years on the clock. That’s where [bison] recently found …read more

The Golden Age of Ever-Changing Computer Architecture

Given the accuracy of Moore’s Law to the development of integrated circuits over the years, one would think that our present day period is no different from the past decades in terms of computer architecture design. However, during the 2017 ACM Turing Award acceptance speech, John L. Hennessy and David …read more

3D Print Your Very Own Mechanical Computer

Most Hackaday readers are familiar with computers from the 70s and 80s, but what about ones even older than that? The Digi Comp 1 was a commercially available computer from the 1960s that actually cost less than a modern-day microcontroller. The catch? It was mechanical rather than electrical. Thanks to …read more

Proprietary Fan Blows, Gets PWM Upgrade

Proprietary components are the bane of anyone who dares to try and repair their own hardware. Nonstandard sizes, lack of labeling or documentation, and unavailable spare parts are all par for the course. [Jason] was unlucky enough to have an older Dell computer with a broken, and proprietary, cooling fan …read more

A DIY Retrocomputer Programmed in Pure Rust

Can you generate VGA and handle a PS/2 keyboard with a Cortex-M4 in Rust? That’s precisely what [theJPster] wanted to find out with Monotron, a 1980s style home computer programmed in pure Rust.

In order to run embedded Rust without a working operating system, some tools are necessary: an LLVM …read more

Dual Screen Laptop Is A Slick DIY Build

Laptops are great for portable productivity, but ergonomically they can leave something to be desired. They tend to force the user to look down, creating neck strain over extended periods. Rather than invest in expensive massages, [DIY Perks] decided what he really wanted was a dual screen laptop. So he …read more

An Arduino Enhances This 7400 CPU

How quickly could you make an entire computer from 74 series logic, from scratch? [Richard Grafton had only 30 days until the UK’s Retro Computer Festival and set out to design and build his Cambridge-1 computer in that time. The result is a machine spread across several breadboards, with neatly …read more
