Realtime cycle exact emulation of the C64 using multiple microcontrollers in parallel. - c1570/Connomore64

Picasso and the Z80 microprocessor are not two things we often think about at the same time. One is a renowned artist born in the 19th century, the other, a popular CPU that helped launch the micro…

: 'We thought it was a really obvious way to build a processor and everybody would be doing it'

When was the last time you saw a computer actually outlast your weekend trip – and then some? Enter the Evertop, a portable IBM XT emulator powered by an ESP32 that doesn’t just flirt w…

Building a Commodore 64 is among the easier projects for retrocomputing fans to tackle. That’s because the C64’s core chipset does most of the heavy lifting; source those and you’…

Long before the Java Virtual Machine (JVM) was said to take the world by storm, the p-System  (pseudo-system, or virtual machine) developed at the University of California, San Diego (UCSD) provide…

In the dark ages, before iOS and Android phones became ubiquitous, there was the PDA. These handheld computers acted as simple companions to a computer and could often handle calendars, email, note…

Emulate the original Macintosh for around $20 (or less) on Raspberry Pi Pico hardware.

Forth is popular on small computers because it is simple to implement, yet quite powerful. But what happens when you really need to shrink it? Well, if your target is the 6502, there’s milliF…

Will a 486 run Crysis? No, of course not. Will it run a large language model (LLM)? Given the huge buildout of compute power to do just that, many people would scoff at the very notion. But [Yeo Kh…
