Open Source Universal ROM Programmer Grows Up

When we first looked at [Anders Nielsen’s] EEPROM programmer project, it was nice but needed some software and manual intervention and had some limitations on the parts you could program. But…

PicoROM, A DIP-32 8-Bit ROM Emulator

As we all know, when developing software for any platform or simply hacking a bit of code to probe how something works, the ability to deploy code rapidly is a huge help. [Martin Donlon], aka [wick…

Using EPROMS And EEPROMs As Programmable Logic With Lisp

That EPROMs, EEPROMs and kin can be used as programmable logic should probably not come as a major surprise, but [Jimmy] has created a Lisp-based project that makes using these chips as a logic arr…

Working With Old High-Voltage EPROMs Is Fussy

EPROMs, those UV-erasable memory chips of the 80s and 90s, once played a crucial role in countless electronic devices. They’ve become relics of a bygone era, but for enthusiasts of vintage el…

EPROM Does VGA

If you wanted to create a VGA card, you might think about using an FPGA. But there are simpler ways to generate patterns, including an old-fashioned EPROM, as [DrMattRegan] points out in a recent v…

Exploring The History Of EPROM In The Soviet Union

An article on the history of EPROMs in the Soviet Union by [Vladimir Yakovlev] over at The CPU Shack Museum caught our attention. It is part one of a series on the topic, and walks you through the …

It’s Bad Apple, But On A 32K EPROM

The Bad Apple!! video with its silhouette animation style has long been a staple graphics demo for low-end hardware, a more stylish alternative to the question “Will it run DOOM?”. It&#…

Pi Pico Emulates ROM For Speedy Retro Hacking

If you’ve ever worked on a system that loads its software from a ROM or EPROM, you know how much of a hassle it can be to make frequent changes to the code. Pulling the chip, flashing it, and…

Proto-PDA Regains Its Memory With The Help Of A Raspberry Pi Pico

Remember the Psion Organiser? If you do, chances are you were an early adopter, as the 8-bit pocket computer had its heyday in the mid-1980s. Things have come a long way since then, of course, but …

Build A Barebones 68000

The 68000 chip was ubiquitous in the computing world well past its heyday in the 1980s. It was used as the basis for many PCs and video game consoles, and even in embedded microcontrollers. Now, on…

Just How Vulnerable To Accidental Erasure Are EPROMs Anyway?

On the scale of things worth worrying about, having to consider whether your EPROMs will be accidentally erased by some stray light in the shop is probably pretty low on the list. Still, losing irr…
