retro computing

Retro Game Mechanics Explained shows how the Atari 2600 draws images with almost no video memory, by having the CPU race the CRT beam line by line. It walks through the techniques in detail.

Veritasium explains why analog computing may suit AI workloads, covering old analog computers, The Analog Thing and Mythic's analog chips that use flash memory for neural network inference. It argues digital hardware is hitting limits.

8-Bit Show And Tell walks through the BASIC source code of the original Commodore 64 Sid Meier's Pirates!. It covers bugs, quirks and traces of abandoned features and scenarios left in the code.

Modern Vintage Gamer explains why PlayStation 1 graphics warped and jittered, comparing it with the Nintendo 64. The causes are affine texture mapping and the lack of sub-pixel vertex precision.

Retro Game Mechanics Explained dissects how Atari's Quadrascan vector displays and vector generator hardware drew games like Asteroids and Tempest.

Noodle explores how retro pixel art was designed for CRT displays and why games look different on LCDs, with input from pixel artists and CRT researchers.

An episode of Plogue's chipresearch series on emulating the Yamaha DX7 from the hardware up. It covers the sub CPU and main CPU, address map investigation, cartridges, firmware analysis and a skeleton MAME driver.

Moon Channel, run by a lawyer, explains the legal basis for emulation, including the history of emulation case law and Nintendo's takedown of Dolphin's Steam release. It argues the legality of emulators is more fragile than most people assume.

An Asianometry explainer on why the Soviet Union, once a leading computing power, fell far behind the US in computers by the 1980s. It traces the gap from the 1960s onward despite strong state support for science.

Huygens Optics explains the Fourier transform and shows how a lens performs one optically. A DLP projector is used as a Fourier filter to do simple pattern recognition on lithographic character patterns.

Veritasium traces analog computers from the Antikythera mechanism and Kelvin's tide-predicting machines to fire control and modern analog approaches. It explains how these machines computed continuously rather than digitally.

Sabine Hossenfelder explains the delayed choice quantum eraser and argues it does not rewrite the past, as popular accounts claim. She walks through what the experiment actually shows.

Kaze Emanuar explains how he rewrote and optimized the Super Mario 64 source code so it runs far faster on real N64 hardware. He covers performance bottlenecks and fixes in detail for his ROM hacks.

Dave Plummer tours the IBM z16 mainframe from design through factory assembly, test lab, accelerators and water cooling. He explains why mainframes still exist and what makes them reliable.

A short Coding Secrets episode explaining why hitting a Sonic 3D cartridge triggers a hidden level select. The cause was a custom crash handler that redirected CPU error interrupts to the level select screen.

Modern Vintage Gamer looks at OpenLara, an open source Tomb Raider engine, running on the Game Boy Advance. The video explains how the port achieves playable speeds on the GBA's slow ARM CPU, with input from the developer XProger.

Quanta Magazine explains the 2022 experiment that claimed to create a holographic wormhole on Google's quantum computer. The description now notes that a later independent analysis questioned whether any wormhole was created.

Veritasium's explainer on Godel's incompleteness theorems and the limits of mathematical proof, tracing set theory, Hilbert's program and the road to Turing and modern computing.

Scott Manley explains the thermal balance of spacecraft and how a satellite could be configured to radiate away the heat from datacenter-scale computing in space. His rough numbers suggest it is feasible.
